Subject: ocfs2: fix oops when writing cloned file
Writing a cloned file triggers a kernel oops and the user-space command
process is also killed by the system. The bug can be reproduced stably
via:
1) create a file under ocfs2 file system directory.
journalctl -b > aa.txt
2) create a cloned file for this file.
reflink aa.txt bb.txt
3) write the cloned file with dd command.
dd if=/dev/zero of=bb.txt bs=512 count=1 conv=notrunc
The dd command is killed by the kernel, then you can see the oops message
via dmesg command.

Subject: mm/page_alloc.c: fix uninitialized memmaps on a partially populated last section
Patch series "mm: fix max_pfn not falling on section boundary", v2.
Playing with different memory sizes for a x86-64 guest, I discovered that
some memmaps (highest section if max_mem does not fall on the section
boundary) are marked as being valid and online, but contain garbage. We
have to properly initialize these memmaps.
Looking at /proc/kpageflags and friends, I found some more issues,
partially related to this.
This patch (of 3):
If max_pfn is not aligned to a section boundary, we can easily run into
BUGs. This can e.g., be triggered on x86-64 under QEMU by specifying a
memory size that is not a multiple of 128MB (e.g., 4097MB, but also
4160MB). I was told that on real HW, we can easily have this scenario
(esp., one of the main reasons sub-section hotadd of devmem was added).
The issue is, that we have a valid memmap (pfn_valid()) for the whole
section, and the whole section will be marked "online".
pfn_to_online_page() will succeed, but the memmap contains garbage.
E.g., doing a "./page-types -r -a 0x144001" when QEMU was started with "-m
4160M" - (see tools/vm/page-types.c):

This patch fixes that by at least zero-ing out that memmap (so e.g.,
page_to_pfn() will not crash). Commit 907ec5fca3dc ("mm: zero remaining
unavailable struct pages") tried to fix a similar issue, but forgot to
consider this special case.
After this patch, there are still problems to solve. E.g., not all of
these pages falling into a memory hole will actually get initialized later
and set PageReserved - they are only zeroed out - but at least the
immediate crashes are gone. A follow-up patch will take care of this.

Subject: fs/proc/page.c: allow inspection of last section and fix end detection
If max_pfn does not fall onto a section boundary, it is possible to
inspect PFNs up to max_pfn, and PFNs above max_pfn, however, max_pfn
itself can't be inspected. We can have a valid (and online) memmap at and
above max_pfn if max_pfn is not aligned to a section boundary. The whole
early section has a memmap and is marked online. Being able to inspect
the state of these PFNs is valuable for debugging, especially because
max_pfn can change on memory hotplug and expose these memmaps.
Also, querying page flags via "./page-types -r -a 0x144001,"
(tools/vm/page-types.c) inside a x86-64 guest with 4160MB under QEMU
results in an (almost) endless loop in user space, because the end is not
detected properly when starting after max_pfn.
Instead, let's allow to inspect all pages in the highest section and
return 0 directly if we try to access pages above that section.
While at it, check the count before adjusting it, to avoid masking user
errors.

Subject: mm/page_alloc.c: initialize memmap of unavailable memory directly
Let's make sure that all memory holes are actually marked PageReserved(),
that page_to_pfn() produces reliable results, and that these pages are not
detected as "mmap" pages due to the mapcount.
E.g., booting a x86-64 QEMU guest with 4160 MB:
[ 0.010585] Early memory node ranges
[ 0.010586] node 0: [mem 0x0000000000001000-0x000000000009efff]
[ 0.010588] node 0: [mem 0x0000000000100000-0x00000000bffdefff]
[ 0.010589] node 0: [mem 0x0000000100000000-0x0000000143ffffff]
max_pfn is 0x144000.
Before this change:
[root@localhost ~]# ./page-types -r -a 0x144000,
flags page-count MB symbolic-flags long-symbolic-flags
0x0000000000000800 16384 64 ___________M_______________________________ mmap
total 16384 64
After this change:
[root@localhost ~]# ./page-types -r -a 0x144000,
flags page-count MB symbolic-flags long-symbolic-flags
0x0000000100000000 16384 64 ___________________________r_______________ reserved
total 16384 64
IOW, especially the unavailable physical memory ("memory hole") in the
last section would not get properly marked PageReserved() and is indicated
to be "mmap" memory.
Drop the trace of that function from include/linux/mm.h - nobody else
needs it, and rename it accordingly.
Note: The fake zone/node might not be covered by the zone/node span. This
is not an urgent issue (for now, we had the same node/zone due to the
zeroing). We'll need a clean way to mark memory holes (e.g., using a page
type PageHole() if possible or a fake ZONE_INVALID) and eventually stop
marking these memory holes PageReserved().

Subject: mm/page_alloc: fix and rework pfn handling in memmap_init_zone()
Let's update the pfn manually whenever we continue the loop. This makes
the code easier to read but also less error prone (and we can directly fix
one issue).
When overlap_memmap_init() returns true, pfn is updated to
"memblock_region_memory_end_pfn(r)". So it already points at the *next*
pfn to process. Incrementing the pfn another time is wrong, we might
leave one uninitialized. I spotted this by inspecting the code, so I have
no idea if this is relevant in practise (with kernelcore=3Dmirror).

Subject: mm: factor out next_present_section_nr()
Let's move it to the header and use the shorter variant from
mm/page_alloc.c (the original one will also check
"__highest_present_section_nr + 1", which is not necessary). While at it,
make the section_nr in next_pfn() const.
In next_pfn(), we now return section_nr_to_pfn(-1) instead of -1 once we
exceed __highest_present_section_nr, which doesn't make a difference i= n
the caller as it is big enough (>=3D all sane end_pfn).

Subject: mm/memmap_init: update variable name in memmap_init_zone
Patch series "mm/memory_hotplug: Shrink zones before removing memory", v6.
This series fixes the access of uninitialized memmaps when shrinking
zones/nodes and when removing memory. Also, it contains all fixes for
crashes that can be triggered when removing certain namespace using
memunmap_pages() - ZONE_DEVICE, reported by Aneesh.
We stop trying to shrink ZONE_DEVICE, as it's buggy, fixing it would be
more involved (we don't have SECTION_IS_ONLINE as an indicator), and
shrinking is only of limited use (set_zone_contiguous() cannot detect the
ZONE_DEVICE as contiguous).
We continue shrinking !ZONE_DEVICE zones, however, I reduced the amount of
code to a minimum. Shrinking is especially necessary to keep
zone->contiguous set where possible, especially, on memory unplug of DIMMs
at zone boundaries.
--------------------------------------------------------------------------
Zones are now properly shrunk when offlining memory blocks or when
onlining failed. This allows to properly shrink zones on memory unplug
even if the separate memory blocks of a DIMM were onlined to different
zones or re-onlined to a different zone after offlining.
Example:
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 0
present 0
managed 0
:/# echo "online_movable" > /sys/devices/system/memory/memory41/state
:/# echo "online_movable" > /sys/devices/system/memory/memory43/state
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 98304
present 65536
managed 65536
:/# echo 0 > /sys/devices/system/memory/memory43/online
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 32768
present 32768
managed 32768
:/# echo 0 > /sys/devices/system/memory/memory41/online
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 0
present 0
managed 0
This patch (of 6):
The third argument is actually number of pages. Change the variable name
from size to nr_pages to indicate this better.
No functional change in this patch.

Let's poison the pages similar to when adding new memory in
sparse_add_section(). Also call remove_pfn_range_from_zone() from
memunmap_pages(), so we can poison the memmap from there as well.

Subject: smp_mb__{before,after}_atomic(): update Documentation
When adding the _{acquire|release|relaxed}() variants of some atomic
operations, it was forgotten to update Documentation/memory_barrier.txt:
smp_mb__{before,after}_atomic() is now intended for all RMW operations
that do not imply a memory barrier.
1)
smp_mb__before_atomic();
atomic_add();
2)
smp_mb__before_atomic();
atomic_xchg_relaxed();
3)
smp_mb__before_atomic();
atomic_fetch_add_relaxed();
Invalid would be:
smp_mb__before_atomic();
atomic_set();
In addition, the patch splits the long sentence into multiple shorter
sentences.

Subject: ipc/mqueue.c: update/document memory barriers
Update and document memory barriers for mqueue.c:
- ewp->state is read without any locks, thus READ_ONCE is required.
- add smp_aquire__after_ctrl_dep() after the READ_ONCE, we need
acquire semantics if the value is STATE_READY.
- use wake_q_add_safe()
- document why __set_current_state() may be used:
Reading task->state cannot happen before the wake_q_add() call,
which happens while holding info->lock. Thus the spin_unlock()
is the RELEASE, and the spin_lock() is the ACQUIRE.
For completeness: there is also a 3 CPU scenario, if the to be woken
up task is already on another wake_q.
Then:
- CPU1: spin_unlock() of the task that goes to sleep is the RELEASE
- CPU2: the spin_lock() of the waker is the ACQUIRE
- CPU2: smp_mb__before_atomic inside wake_q_add() is the RELEASE
- CPU3: smp_mb__after_spinlock() inside try_to_wake_up() is the ACQUIRE

Subject: ipc/msg.c: update and document memory barriers
Transfer findings from ipc/mqueue.c:
- A control barrier was missing for the lockless receive case So in
theory, not yet initialized data may have been copied to user space -
obviously only for architectures where control barriers are not NOP.
- use smp_store_release(). In theory, the refount may have been
decreased to 0 already when wake_q_add() tries to get a reference.

Subject: ipc/msg.c: consolidate all xxxctl_down() functions
A use of uninitialized memory in msgctl_down() because msqid64 in
ksys_msgctl hasn't been initialized. The local | msqid64 | is created in
ksys_msgctl() and then passed into msgctl_down(). Along the way msqid64
is never initialized before msgctl_down() checks msqid64->msg_qbytes.

Since 5.5-rc1 the last user of this function is gone, so remove the
functionality.
See commit

Subject: mm: add generic p?d_leaf() macros
Patch series "Generic page walk and ptdump", v17.
Many architectures current have a debugfs file for dumping the kernel page
tables. Currently each architecture has to implement custom functions for
this because the details of walking the page tables used by the kernel are
different between architectures.
This series extends the capabilities of walk_page_range() so that it can
deal with the page tables of the kernel (which have no VMAs and can
contain larger huge pages than exist for user space). A generic PTDUMP
implementation is the implemented making use of the new functionality of
walk_page_range() and finally arm64 and x86 are switch to using it,
removing the custom table walkers.
To enable a generic page table walker to walk the unusual mappings of the
kernel we need to implement a set of functions which let us know when the
walker has reached the leaf entry. After a suggestion from Will Deacon
I've chosen the name p?d_leaf() as this (hopefully) describes the purpose
(and is a new name so has no historic baggage). Some architectures have
p?d_large macros but this is easily confused with "large pages".
This series ends with a generic PTDUMP implemention for arm64 and x86.
Mostly this is a clean up and there should be very little functional
change. The exceptions are:
* arm64 PTDUMP debugfs now displays pages which aren't present (patch 22).
* arm64 has the ability to efficiently process KASAN pages (which
previously only x86 implemented). This means that the combination of
KASAN and DEBUG_WX is now useable.
This patch (of 23):
Exposing the pud/pgd levels of the page tables to walk_page_range() means
we may come across the exotic large mappings that come with large areas of
contiguous memory (such as the kernel's linear map).
For architectures that don't provide all p?d_leaf() macros, provide
generic do nothing default that are suitable where there cannot be leaf
pages at that level. Futher patches will add implementations for
individual architectures.
The name p?d_leaf() is chosen to minimize the confusion with existing uses
of "large" pages and "huge" pages which do not necessary mean that the
entry is a leaf (for example it may be a set of contiguous entries that
only take 1 TLB slot). For the purpose of walking the page tables we
don't need to know how it will be represented in the TLB, but we do need
to know for sure if it is a leaf of the tree.

walk_page_range() is going to be allowed to walk page tables other than
those of user space. For this it needs to know when it has reached a
'leaf' entry in the page tables. This information will be provided by the
p?d_leaf() functions/macros.
For arc, we only have two levels, so only pmd_leaf() is needed.

those of user space. For this it needs to know when it has reached a
'leaf' entry in the page tables. This information will be provided by the
p?d_leaf() functions/macros.
For arm64, we already have p?d_sect() macros which we can reuse for
p?d_leaf().
pud_sect() is defined as a dummy function when CONFIG_PGTABLE_LEVELS < 3
or CONFIG_ARM64_64K_PAGES is defined. However when the kernel is
configured this way then architecturally it isn't allowed to have a large
page at this level, and any code using these page walking macros is
implicitly relying on the page size/number of levels being the same as the
kernel. So it is safe to reuse this for p?d_leaf() as it is an
architectural restriction.

Subject: mips: mm: add p?d_leaf() definitions
walk_page_range() is going to be allowed to walk page tables other than
those of user space. For this it needs to know when it has reached a
'leaf' entry in the page tables. This information is provided by the
p?d_leaf() functions/macros.
If _PAGE_HUGE is defined we can simply look for it. When not defined we
can be confident that there are no leaf pages in existence and fall back
on the generic implementation (added in a later patch) which returns 0.

From: Steven Price <steven.price@arm.com>
Subject: mm: pagewalk: add p4d_entry() and pgd_entry()
pgd_entry() and pud_entry() were removed by commit 0b1fbfe50006c410
("mm/pagewalk: remove pgd_entry() and pud_entry()") because there were no
users. We're about to add users so reintroduce them, along with
p4d_entry() as we now have 5 levels of tables.
Note that commit a00cc7d9dd93d66a ("mm, x86: add support for PUD-sized
transparent hugepages") already re-added pud_entry() but with different
semantics to the other callbacks. This commit reverts the semantics back
to match the other callbacks.
To support hmm.c which now uses the new semantics of pud_entry() a new
member ('action') of struct mm_walk is added which allows the callbacks to
either descend (ACTION_SUBTREE, the default), skip (ACTION_CONTINUE) or
repeat the callback (ACTION_AGAIN). hmm.c is then updated to call
pud_trans_huge_lock() itself and make use of the splitting/retry logic of
the core code.
After this change pud_entry() is called for all entries, not just
transparent huge pages.

Subject: mm: pagewalk: allow walking without vma
Since 48684a65b4e3: "mm: pagewalk: fix misbehavior of walk_page_range for
vma(VM_PFNMAP)", page_table_walk() will report any kernel area as a hole,
because it lacks a vma.
This means each arch has re-implemented page table walking when needed,
for example in the per-arch ptdump walker.
Remove the requirement to have a vma in the generic code and add a new
function walk_page_range_novma() which ignores the VMAs and simply walks
the page tables.

Subject: mm: pagewalk: don't lock PTEs for walk_page_range_novma()
walk_page_range_novma() can be used to walk page tables or the kernel or
for firmware. These page tables may contain entries that are not backed
by a struct page and so it isn't (in general) possible to take the PTE
lock for the pte_entry() callback. So update walk_pte_range() to only
take the lock when no_vma==false by splitting out the inner loop to a
separate function and add a comment explaining the difference to
walk_page_range_novma().

Subject: mm: pagewalk: fix termination condition in walk_pte_range()
If walk_pte_range() is called with a 'end' argument that is beyond the
last page of memory (e.g. ~0UL) then the comparison between 'addr' and
'end' will always fail and the loop will be infinite. Instead change the
comparison to >= while accounting for overflow.

From: Steven Price <steven.price@arm.com>
Subject: mm: pagewalk: add 'depth' parameter to pte_hole
The pte_hole() callback is called at multiple levels of the page tables.
Code dumping the kernel page tables needs to know what at what depth the
missing entry is. Add this is an extra parameter to pte_hole(). When the
depth isn't know (e.g. processing a vma) then -1 is passed.
The depth that is reported is the actual level where the entry is missing
(ignoring any folding that is in place), i.e. any levels where
PTRS_PER_P?D is set to 1 are ignored.
Note that depth starts at 0 for a PGD so that PUD/PMD/PTE retain their
natural numbers as levels 2/3/4.

Subject: x86: mm: point to struct seq_file from struct pg_state
mm/dump_pagetables.c passes both struct seq_file and struct pg_state down
the chain of walk_*_level() functions to be passed to note_page().
Instead place the struct seq_file in struct pg_state and access it from

Subject: x86: mm+efi: convert ptdump_walk_pgd_level() to take a mm_struct
To enable x86 to use the generic walk_page_range() function, the callers
of ptdump_walk_pgd_level() need to pass an mm_struct rather than the raw
pgd_t pointer. Luckily since commit 7e904a91bf60 ("efi: Use efi_mm in x86
as well as ARM") we now have an mm_struct for EFI on x86.

To enable x86 to use the generic walk_page_range() function, the callers
of ptdump_walk_pgd_level_debugfs() need to pass in the mm_struct.
This means that ptdump_walk_pgd_level_core() is now always passed a valid
pgd, so drop the support for pgd==NULL.

Subject: x86: mm: convert ptdump_walk_pgd_level_debugfs() to take an mm_struct
To enable x86 to use the generic walk_page_range() function, the callers
of ptdump_walk_pgd_level_debugfs() need to pass in the mm_struct.
This means that ptdump_walk_pgd_level_core() is now always passed a valid
pgd, so drop the support for pgd==NULL.

Subject: x86: mm: convert dump_pagetables to use walk_page_range
Make use of the new functionality in walk_page_range to remove the arch
page walking code and use the generic code to walk the page tables.
The effective permissions are passed down the chain using new fields in
struct pg_state.
The KASAN optimisation is implemented by setting action=CONTINUE in the
callbacks to skip an entire tree of entries.

Subject: arm64: mm: convert mm/dump.c to use walk_page_range()
Now walk_page_range() can walk kernel page tables, we can switch the arm64
ptdump code over to using it, simplifying the code.

Subject: arm64: mm: display non-present entries in ptdump
Previously the /sys/kernel/debug/kernel_page_tables file would only show
lines for entries present in the page tables. However it is useful to
also show non-present entries as this makes the size and level of the
holes more visible. This aligns the behaviour with x86 which also shows
holes.

Subject: mm: ptdump: reduce level numbers by 1 in note_page()
Rather than having to increment the 'depth' number by 1 in ptdump_hole(),
let's change the meaning of 'level' in note_page() since that makes the
code simplier.
Note that for x86, the level numbers were previously increased by 1 in
commit 45dcd2091363 ("x86/mm/dump_pagetables: Fix printout of p4d level")
and the comment "Bit 7 has a different meaning" was not updated, so this
change also makes the code match the comment again.

From: Steven Price <steven.price@arm.com>
Subject: x86: mm: avoid allocating struct mm_struct on the stack
struct mm_struct is quite large (~1664 bytes) and so allocating on the
stack may cause problems as the kernel stack size is small.
Since ptdump_walk_pgd_level_core() was only allocating the structure so
that it could modify the pgd argument we can instead introduce a pgd
override in struct mm_walk and pass this down the call stack to where it
is needed.
Since the correct mm_struct is now being passed down, it is now also
unnecessary to take the mmap_sem semaphore because ptdump_walk_pgd() will
now take the semaphore on the real mm.

From: Steven Price <steven.price@arm.com>
Subject: x86: mm: avoid allocating struct mm_struct on the stack
struct mm_struct is quite large (~1664 bytes) and so allocating on the
stack may cause problems as the kernel stack size is small.
Since ptdump_walk_pgd_level_core() was only allocating the structure so
that it could modify the pgd argument we can instead introduce a pgd
override in struct mm_walk and pass this down the call stack to where it
is needed.
Since the correct mm_struct is now being passed down, it is now also
unnecessary to take the mmap_sem semaphore because ptdump_walk_pgd() will
now take the semaphore on the real mm.

From: "Aneesh Kumar K.V" <aneesh.kumar@linux.ibm.com>
Subject: powerpc/mmu_gather: enable RCU_TABLE_FREE even for !SMP case
Patch series "Fixup page directory freeing", v4.
This is a repost of patch series from Peter with the arch specific changes
except ppc64 dropped. ppc64 changes are added here because we are redoing
the patch series on top of ppc64 changes. This makes it easy to backport
these changes. Only the first 2 patches need to be backported to stable.
The thing is, on anything SMP, freeing page directories should observe the
exact same order as normal page freeing:
1) unhook page/directory
2) TLB invalidate
3) free page/directory
Without this, any concurrent page-table walk could end up with a
Use-after-Free. This is esp. trivial for anything that has software
page-table walkers (HAVE_FAST_GUP / software TLB fill) or the hardware
caches partial page-walks (ie. caches page directories).
Even on UP this might give issues since mmu_gather is preemptible these
days. An interrupt or preempted task accessing user pages might stumble
into the free page if the hardware caches page directories.
This patch series fixes ppc64 and add generic MMU_GATHER changes to
support the conversion of other architectures. I haven't added patches
w.r.t other architecture because they are yet to be acked.
This patch (of 9):
A followup patch is going to make sure we correctly invalidate page walk
cache before we free page table pages. In order to keep things simple
enable RCU_TABLE_FREE even for !SMP so that we don't have to fixup the
!SMP case differently in the followup patch
!SMP case is right now broken for radix translation w.r.t page walk
cache flush. We can get interrupted in between page table free and
that would imply we have page walk cache entries pointing to tables
which got freed already. Michael said "both our platforms that run on
Power9 force SMP on in Kconfig, so the !SMP case is unlikely to be a
problem for anyone in practice, unless they've hacked their kernel to
build it !SMP."

Subject: mm/mmu_gather: invalidate TLB correctly on batch allocation failure and flush
Architectures for which we have hardware walkers of Linux page table
should flush TLB on mmu gather batch allocation failures and batch flush.
Some architectures like POWER supports multiple translation modes (hash
and radix) and in the case of POWER only radix translation mode needs the
above TLBI. This is because for hash translation mode kernel wants to
avoid this extra flush since there are no hardware walkers of linux page
table. With radix translation, the hardware also walks linux page table
and with that, kernel needs to make sure to TLB invalidate page walk cache
before page table pages are freed.
More details in commit d86564a2f085 ("mm/tlb, x86/mm: Support invalidating
TLB caches for RCU_TABLE_FREE")
The changes to sparc are to make sure we keep the old behavior since we
are now removing HAVE_RCU_TABLE_NO_INVALIDATE. The default value for
tlb_needs_table_invalidate is to always force an invalidate and sparc can
avoid the table invalidate. Hence we define tlb_needs_table_invalidate to
false for sparc architecture.

Subject: asm-generic/tlb: avoid potential double flush
Aneesh reported that:
tlb_flush_mmu()
tlb_flush_mmu_tlbonly()
tlb_flush() <-- #1
tlb_flush_mmu_free()
tlb_table_flush()
tlb_table_invalidate()
tlb_flush_mmu_tlbonly()
tlb_flush() <-- #2
does two TLBIs when tlb->fullmm, because __tlb_reset_range() will not
clear tlb->end in that case.
Observe that any caller to __tlb_adjust_range() also sets at least one of
the tlb->freed_tables || tlb->cleared_p* bits, and those are
unconditionally cleared by __tlb_reset_range().
Change the condition for actually issuing TLBI to having one of those bits
set, as opposed to having tlb->end != 0.

Subject: asm-generic/tlb: provide MMU_GATHER_TABLE_FREE
As described in the comment, the correct order for freeing pages is:
1) unhook page
2) TLB invalidate page
3) free page
This order equally applies to page directories.
Currently there are two correct options:
- use tlb_remove_page(), when all page directores are full pages and
there are no futher contraints placed by things like software
walkers (HAVE_FAST_GUP).
- use MMU_GATHER_RCU_TABLE_FREE and tlb_remove_table() when the
architecture does not do IPI based TLB invalidate and has
HAVE_FAST_GUP (or software TLB fill).
This however leaves architectures that don't have page based directories
but don't need RCU in a bind. For those, provide MMU_GATHER_TABLE_FREE,
which provides the independent batching for directories without the
additional RCU freeing.

From: Alexey Dobriyan <adobriyan@gmail.com>
Subject: proc: decouple proc from VFS with "struct proc_ops"
Currently core /proc code uses "struct file_operations" for custom hooks,
however, VFS doesn't directly call them. Every time VFS expands
file_operations hook set, /proc code bloats for no reason.
Introduce "struct proc_ops" which contains only those hooks which /proc
allows to call into (open, release, read, write, ioctl, mmap, poll). It
doesn't contain module pointer as well.

To: adobriyan, akpm, linux-mm, mm-commits, sfr, torvalds
From: Alexey Dobriyan <adobriyan@gmail.com>
Subject: proc: convert everything to "struct proc_ops"
The most notable change is DEFINE_SHOW_ATTRIBUTE macro split in
seq_file.h.
Conversion rule is:
llseek => proc_lseek
unlocked_ioctl => proc_ioctl
xxx => proc_xxx
delete ".owner = THIS_MODULE" line

From: Yury Norov <yury.norov@gmail.com>
Subject: lib/string: add strnchrnul()
Patch series "lib: rework bitmap_parse", v5.
Similarl to the recently revisited bitmap_parselist(), bitmap_parse() is
ineffective and overcomplicated. This series reworks it, aligns its
interface with bitmap_parselist() and makes it simpler to use.
The series also adds a test for the function and fixes usage of it in
cpumask_parse() according to the new design - drops the calculating of
length of an input string.
bitmap_parse() takes the array of numbers to be put into the map in the BE
order which is reversed to the natural LE order for bitmaps. For example,
to construct bitmap containing a bit on the position 42, we have to put a
line '400,0'. Current implementation reads chunk one by one from the
beginning ('400' before '0') and makes bitmap shift after each successful
parse. It makes the complexity of the whole process as O(n^2). We can do
it in reverse direction ('0' before '400') and avoid shifting, but it
requires reverse parsing helpers.
This patch (of 7):
New function works like strchrnul() with a length limited string.

Subject: bitops: more BITS_TO_* macros
Introduce BITS_TO_U64, BITS_TO_U32 and BITS_TO_BYTES as they are handy in
the following patches (BITS_TO_U32 specifically). Reimplement tools/
version of the macros according to the kernel implementation.
Also fix indentation for BITS_PER_TYPE definition.

Subject: lib: make bitmap_parse_user a wrapper on bitmap_parse
Currently we parse user data byte after byte which leads to
overcomplicating of parsing algorithm. There are no performance critical
users of bitmap_parse_user(), and so we can duplicate user data to kernel
buffer and simply call bitmap_parselist(). This rework lets us unify and
simplify bitmap_parse() and bitmap_parse_user(), which is done in the
following patch.

From: Yury Norov <yury.norov@gmail.com>
Subject: lib: rework bitmap_parse()
bitmap_parse() is ineffective and full of opaque variables and opencoded
parts. It leads to hard understanding and usage of it. This rework
includes:
- remove bitmap_shift_left() call from the cycle. Now it makes the
complexity of the algorithm as O(nbits^2). In the suggested approach
the input string is parsed in reverse direction, so no shifts needed;
- relax requirement on a single comma and no white spaces between
chunks. It is considered useful in scripting, and it aligns with
bitmap_parselist();
- split bitmap_parse() to small readable helpers;
- make an explicit calculation of the end of input line at the
beginning, so users of the bitmap_parse() won't bother doing this.

From: Yury Norov <yury.norov@gmail.com>
Subject: lib: new testcases for bitmap_parse{_user}
New version of bitmap_parse() is unified with bitmap_parse_list(),
and therefore:
- weakens rules on whitespaces and commas between hex chunks;
- in addition to
- allows passing UINT_MAX or any other big number as the length of input
string instead of actual string length.
The patch covers the cases.

Subject: treewide: remove redundant IS_ERR() before error code check
'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p).
Hence, IS_ERR(p) is unneeded.
The semantic patch that generates this commit is as follows:
// <smpl>
@@
expression ptr;
constant error_code;
@@
-IS_ERR(ptr) && (PTR_ERR(ptr) == - error_code)
+PTR_ERR(ptr) == - error_code

From: Chen-Yu Tsai <wens@csie.org>
Subject: ARM: dma-api: fix max_pfn off-by-one error in __dma_supported()
max_pfn, as set in arch/arm/mm/init.c:
static void __init find_limits(unsigned long *min,
unsigned long *max_low,
unsigned long *max_high)
{
*max_low = PFN_DOWN(memblock_get_current_limit());
*min = PFN_UP(memblock_start_of_DRAM());
*max_high = PFN_DOWN(memblock_end_of_DRAM());
}
with memblock_end_of_DRAM() pointing to the next byte after DRAM. As
such, max_pfn points to the PFN after the end of DRAM.
Thus when using max_pfn to check DMA masks, we should subtract one when
checking DMA ranges against it.
Commit 8bf1268f48ad ("ARM: dma-api: fix off-by-one error in
__dma_supported()") fixed the same issue, but missed this spot.
This issue was found while working on the sun4i-csi v4l2 driver on the
Allwinner R40 SoC. On Allwinner SoCs, DRAM is offset at 0x40000000, and
we are starting to use of_dma_configure() with the "dma-ranges" property
in the device tree to have the DMA API handle the offset.
In this particular instance, dma-ranges was set to the same range as the
actual available (2 GiB) DRAM. The following error appeared when the
driver attempted to allocate a buffer:
sun4i-csi 1c09000.csi: Coherent DMA mask 0x7fffffff (pfn 0x40000-0xc0000)
covers a smaller range of system memory than the DMA zone pfn 0x0-0xc0001
sun4i-csi 1c09000.csi: dma_alloc_coherent of size 307200 failed
Fixing the off-by-one error makes things work.

Subject: MIPS: kdb: remove old workaround for backtracing on other CPUs
Patch series "kdb: Don't implicitly change tasks; plus misc fixups".
This patch (of 5):
As of commit 2277b492582d ("kdb: Fix stack crawling on 'running' CPUs that
aren't the master") we no longer need any special case for doing stack
dumps on CPUs that are not the kdb master. Let's remove.

has been removed from the -mm tree. Its filename was

------------------------------------------------------
From: Douglas Anderson <dianders@chromium.org>
Subject: kdb: kdb_current_task shouldn't be exported
The kdb_current_task variable has been declared in
"kernel/debug/kdb/kdb_private.h" since 2010 when kdb was added to the
mainline kernel. This is not a public header. There should be no reason
that kdb_current_task should be exported and there are no in-kernel users
that need it. Remove the export.

Subject: kdb: get rid of implicit setting of the current task/regs
Some (but not all?) of the kdb backtrace paths would cause the
kdb_current_task and kdb_current_regs to remain changed. As discussed in
a review of a previous patch [1], this doesn't seem intuitive, so let's
fix that.
...but, it turns out that there's actually no longer any reason to set the
current task / current regs while backtracing anymore anyway. As of
commit 2277b492582d ("kdb: Fix stack crawling on 'running' CPUs that
aren't the master") if we're backtracing on a task running on a CPU we ask
that CPU to do the backtrace itself. Linux can do that without anything
fancy. If we're doing backtrace on a sleeping task we can also do that
fine without updating globals. So this patch mostly just turns into
deleting a bunch of code.

From: Douglas Anderson <dianders@chromium.org>
Subject: kdb: get rid of confusing diag msg from "rd" if current task has no regs
If you switch to a sleeping task with the "pid" command and then type
"rd", kdb tells you this:
No current kdb registers. You may need to select another task
diag: -17: Invalid register name
The first message makes sense, but not the second. Fix it by just
returning 0 after commands accessing the current registers finish if we've
already printed the "No current kdb registers" error.
While fixing kdb_rd(), change the function to use "if" rather than
"ifdef". It cleans the function up a bit and any modern compiler will
have no trouble handling still producing good code.

Anxdrew,
this whole patch-series seems to be corrupt. Not only was the
"incoming" cover emal missing the base to apply it to, but the patches
themselves are broken too.
See for example this one:

Note that "=3D". That's some MIME stuff that you haven't decoded, and
then sent out as an email as-is.

Same here. That "=\n" shouldn't be in the email, it comes from some
original MIME data that wasn't ever properly decoded.
The *patch* itself seems fine, and the "=" signs are not mime:
> - for (pfn = start_pfn; pfn < end_pfn; pfn++) {
> + for (pfn = start_pfn; pfn < end_pfn; ) {
so it seems that only the actual explanations have gotten corrupted somehow.
Cut-and-paste from some MIME source in a MUA that doesn't know mime?
Or directly from some mbox file without any MIME decoding?

Here, look at that "i= n". It looks like it was a MIME line-break (so
"in" was MIME-encoded and turned into "i=\nn") followed by you or
David re-flowing the text without MIME-decoding it.
And note the ">=3D" thing. It should be just ">=" but again there is
left-over crud from using MIME-encoded data without decoding it.
I am noticing that this has apparently happened before too. And maybe
it's not you. Maybe it's David Hildenbrand that has sent you already
corrupted data.
Doing a
git log --grep="=3D"
shows that this mistake has been done by others before. But it's not
_that_ common. I find 25 occurrences of that "=3D" thing in the logs
over the whole history of the kernel.
The "=\n" thing is much harder to grep for quite that trivially, or
the other "random utf8 encoded as MIME and never decoded properly"
stuff.
But the fact that I found at least _two_ of these cases in just this
series, and it had that broken coverletter too, makes me go "Hmm".
I tried to look for other cases, but those two emails (both from David
Hildenbrand, soo...) were the only ones I found in this series of 67.
I can fix them up, of course, but I really hate how somebody has some
workflow that generates this corruption.
MIME corruption in the patches themselves tends to be much more
obvious ("it doesn't apply" or "it no longer builds"). But in the
commit message it's not always clear. So please be *careful*.
I'm jetlagged in Cambridge UK and was going to apply this series since
I was awake anyway, but now I'm not sure I should do that.
At a minimum I want to know what the base commit was supposed to be..

Ok, I've tentatively applied it with the MIME decoding fixes I found,
and I'll guess I'll let it build and sit for a while before merging it
into my tree.
I didn't find anything else odd in there. But...

Yes, my MUA is not good about converting all input. I have tools to fix
up the patches post-facto but changelogs have been a challenge.
I have updated my nightly check-patches-for-crap-and-email-it-to-andrew
script to check for this.

I'm a simple man - I use vim+git with barely any custom scripts (well,
only a cc-cmd script shared my Michal once). I've been sending patches
from the same machine for years without any such glitches.
The only thing I do manually is copying the cover letter from
Thunderbird + adapting it when resending a version. But as the patch
descriptions themselves are messed up, that doesn't explain the story.
I *suspect* this is the result of (one of many) temporary mail server
issues we had at Red Hat when switching providers (although a weird one
- but I remember there were weird ones).

Subject: mm: don't prepare anon_vma if vma has VM_WIPEONFORK
Patch series "mm: Fix misuse of parent anon_vma in dup_mmap path".
This patchset fixes the misuse of parenet anon_vma, which mainly caused by
child vma's vm_next and vm_prev are left same as its parent after
duplicate vma. Finally, code reached parent vma's neighbor by referring
pointer of child vma and executed wrong logic.
The first two patches fix relevant issues, and the third patch sets
vm_next and vm_prev to NULL when duplicate vma to prevent potential misuse
in future.
This patch (of 3):
In dup_mmap(), anon_vma_prepare() is called for vma has VM_WIPEONFORK, and
parameter 'tmp' (i.e., the new vma of child) has same ->vm_next and
->vm_prev as its parent vma. That allows anon_vma used by parent been
mistakenly shared by child (find_mergeable_anon_vma() will do this reuse
work).
Besides this issue, call anon_vma_prepare() should be avoided because we
don't copy page for this vma. Preparing anon_vma will be handled during
fault.

From: Li Xinhai <lixinhai.lxh@gmail.com>
Subject: Revert "mm/rmap.c: reuse mergeable anon_vma as parent when fork"
This reverts commit 4e4a9eb921332b9d1 ("mm/rmap.c: reuse mergeable
anon_vma as parent when fork").
In dup_mmap(), anon_vma_fork() is called for attaching anon_vma and
parameter 'tmp' (i.e., the new vma of child) has same ->vm_next and
->vm_prev as its parent vma. That causes the anon_vma used by parent been
mistakenly shared by child (In anon_vma_clone(), the code added by that
commit will do this reuse work).
Besides this issue, the design of reusing anon_vma from vma which has gone
through fork should be avoided ([1]). So, this patch reverts that commit
and maintains the consistent logic of reusing anon_vma for
fork/split/merge vma.
[1] commit d0e9fe1758f2 ("Simplify and comment on anon_vma re-use for
anon_vma_prepare()") explains the test of "list_is_singular()".

A shattered l.nr_items could affect the shrinker behaviour due to a data
race. Fix it by adding READ_ONCE() for the read. Since the writes are
aligned and up to word-size, assume those are safe from data races to
avoid readability issues of writing WRITE_ONCE(var, var + val).

From: Brian Geffon <bgeffon@google.com>
Subject: mm/mremap: add MREMAP_DONTUNMAP to mremap()
When remapping an anonymous, private mapping, if MREMAP_DONTUNMAP is set,
the source mapping will not be removed. Instead it will be cleared as if
a brand new anonymous, private mapping had been created atomically as part
of the mremap() call. If a userfaultfd was watching the source, it will
continue to watch the new mapping. For a mapping that is shared or not
anonymous, MREMAP_DONTUNMAP will cause the mremap() call to fail. Because
MREMAP_DONTUNMAP always results in moving a VMA you MUST use the
MREMAP_MAYMOVE flag. The final result is two equally sized VMAs where the
destination contains the PTEs of the source.
We hope to use this in Chrome OS where with userfaultfd we could write an
anonymous mapping to disk without having to STOP the process or worry
about VMA permission changes.
This feature also has a use case in Android, Lokesh Gidra has said that
"As part of using userfaultfd for GC, We'll have to move the physical
pages of the java heap to a separate location. For this purpose mremap
will be used. Without the MREMAP_DONTUNMAP flag, when I mremap the java
heap, its virtual mapping will be removed as well. Therefore, we'll
require performing mmap immediately after. This is not only time
consuming but also opens a time window where a native thread may call mmap
and reserve the java heap's address range for its own usage. This flag
solves the problem."

Subject: mm/sparsemem: get address to page struct instead of address to pfn
memmap should be the address to page struct instead of address to pfn.
As mentioned by David, if system memory and devmem sit within a section,
the mismatch address would lead kdump to dump unexpected memory.
Since sub-section only works for SPARSEMEM_VMEMMAP, pfn_to_page() is valid
to get the page struct address at this point.

The writes are under si->lock but the reads are not. For si.highest_bit
and si.swap_map[offset], data race could trigger logic bugs, so fix them
by having WRITE_ONCE() for the writes and READ_ONCE() for the reads
except those isolated reads where they compare against zero which a data
race would cause no harm. Thus, annotate them as intentional data races
using the data_race() macro.
For si.flags, the readers are only interested in a single bit where a
data race there would cause no issue there.

The write is under &si->lock, but the reads are done as lockless. Since
the reads only check for a specific bit in the flag, it is harmless even
if load tearing happens. Thus, just mark them as intentional data races
using the data_race() macro.

missed a few incremental due to data races, it will be harmless, so just
mark it as an intentional data race using the data_race() macro.

From: Naohiro Aota <naohiro.aota@wdc.com>
Subject: mm/swapfile.c: move inode_lock out of claim_swapfile
claim_swapfile() currently keeps the inode locked when it is successful,
or the file is already swapfile (with -EBUSY). And, on the other error
cases, it does not lock the inode.
This inconsistency of the lock state and return value is quite confusing
and actually causing a bad unlock balance as below in the "bad_swap"
section of __do_sys_swapon().
This commit fixes this issue by moving the inode_lock() and IS_SWAPFILE
check out of claim_swapfile(). The inode is unlocked in
"bad_swap_unlock_inode" section, so that the inode is ensured to be
unlocked at "bad_swap". Thus, error handling codes after the locking now
jumps to "bad_swap_unlock_inode" instead of "bad_swap".
=====================================
WARNING: bad unlock balance detected!
5.5.0-rc7+ #176 Not tainted
-------------------------------------
swapon/4294 is trying to release lock (&sb->s_type->i_mutex_key) at:
[<ffffffff8173a6eb>] __do_sys_swapon+0x94b/0x3550
but there are no more locks to release!

Subject: selftests/vm: add missed tests in run_vmtests
The commits introducing 'mlock-random-test'[1], 'map_fiex_noreplace'[2],
and 'thuge-gen'[3] have not added those in the 'run_vmtests' script and
thus the 'run_tests' command of kselftests doesn't run those. This commit
adds those in the script.
'gup_benchmark' and 'transhuge-stress' are also not included in the
'run_vmtests', but this commit does not add those because those are for
performance measurement rather than pass/fail tests.
[1] commit 26b4224d9961 ("selftests: expanding more mlock selftest")
[2] commit 91cbacc34512 ("tools/testing/selftests/vm/map_fixed_noreplace.c: add test for MAP_FIXED_NOREPLACE")
[3] commit fcc1f2d5dd34 ("selftests: add a test program for variable huge page sizes in mmap/shmget")

Subject: mm, memcg: fix build error around the usage of kmem_caches
When I manually set default n to MEMCG_KMEM in init/Kconfig, bellow error
occurs,
mm/slab_common.c: In function 'memcg_slab_start':
mm/slab_common.c:1530:30: error: 'struct mem_cgroup' has no member named
'kmem_caches'
return seq_list_start(&memcg->kmem_caches, *pos);
^
mm/slab_common.c: In function 'memcg_slab_next':
mm/slab_common.c:1537:32: error: 'struct mem_cgroup' has no member named
'kmem_caches'
return seq_list_next(p, &memcg->kmem_caches, pos);
^
mm/slab_common.c: In function 'memcg_slab_show':
mm/slab_common.c:1551:16: error: 'struct mem_cgroup' has no member named
'kmem_caches'
if (p == memcg->kmem_caches.next)
^
CC arch/x86/xen/smp.o
mm/slab_common.c: In function 'memcg_slab_start':
mm/slab_common.c:1531:1: warning: control reaches end of non-void function
[-Wreturn-type]
}
^
mm/slab_common.c: In function 'memcg_slab_next':
mm/slab_common.c:1538:1: warning: control reaches end of non-void function
[-Wreturn-type]
}
^
That's because kmem_caches is defined only when CONFIG_MEMCG_KMEM is set,
while memcg_slab_start() will use it no matter CONFIG_MEMCG_KMEM is defined
or not.
By the way, the reason I mannuly undefined CONFIG_MEMCG_KMEM is to verify
whether my some other code change is still stable when CONFIG_MEMCG_KMEM is
not set. Unfortunately, the existing code has been already unstable since
v4.11.

The write is under lru_lock, but the read is done as lockless. The scan
count is used to determine how aggressively the anon and file LRU lists
should be scanned. Load tearing could generate an inefficient heuristic,
so fix it by adding READ_ONCE() for the read.

Subject: get_maintainer: Remove uses of P: for maintainer name
commit 1ca84ed6425f ("MAINTAINERS: Reclaim the P: tag for Maintainer Entry
Profile") changed the use of the "P:" tag from "Person" to "Profile (ie:
special subsystem coding styles and characteristics)"
Change how get_maintainer.pl parses the "P:" tag to match.

From: Douglas Anderson <dianders@chromium.org>
Subject: scripts/get_maintainer.pl: deprioritize old Fixes: addresses
Recently, I found that get_maintainer was causing me to send emails to the
old addresses for maintainers. Since I usually just trust the output of
get_maintainer to know the right email address, I didn't even look
carefully and fired off two patch series that went to the wrong place.
Oops.
The problem was introduced recently when trying to add signatures from
Fixes. The problem was that these email addresses were added too early in
the process of compiling our list of places to send. Things added to the
list earlier are considered more canonical and when we later added
maintainer entries we ended up deduplicating to the old address.
Here are two examples using mainline commits (to make it easier to
replicate) for the two maintainers that I messed up recently:
$ git format-patch d8549bcd0529~..d8549bcd0529
$ ./scripts/get_maintainer.pl 0001-clk-Add-clk_hw*.patch | grep Boyd
Stephen Boyd <sboyd@codeaurora.org>...
$ git format-patch 6d1238aa3395~..6d1238aa3395
$ ./scripts/get_maintainer.pl 0001-arm64-dts-qcom-qcs404*.patch | grep Andy
Andy Gross <andy.gross@linaro.org>
Let's move the adding of addresses from Fixes: to the end since the
email addresses from these are much more likely to be older.
After this patch the above examples get the right addresses for the
two examples.

ra.mmap_miss is used to contribute the readahead decisions, a data race
could be undesirable. Both the read and write is only under non-exclusive
mmap_sem, two concurrent writers could even underflow the counter. Fix
the underflow by writing to a local variable before committing a final
store to ra.mmap_miss given a small inaccuracy of the counter should be
acceptable.

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup: split get_user_pages_remote() into two routines
Patch series "mm/gup: track FOLL_PIN pages", v6.
This activates tracking of FOLL_PIN pages. This is in support of fixing
the get_user_pages()+DMA problem described in [1]-[4].
FOLL_PIN support is now in the main linux tree. However, the patch to use
FOLL_PIN to track pages was *not* submitted, because Leon saw an RDMA test
suite failure that involved (I think) page refcount overflows when huge
pages were used.
This patch definitively solves that kind of overflow problem, by adding an
exact pincount, for compound pages (of order > 1), in the 3rd struct page
of a compound page. If available, that form of pincounting is used,
instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara
for that idea.
Other interesting changes:
* dump_page(): added one, or two new things to report for compound
pages: head refcount (for all compound pages), and map_pincount (for
compound pages of order > 1).
* Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the
huge page refcount upper limit problems, and added notes about how it
works now. Also added a note about the dump_page() enhancements.
* Added some comments in gup.c and mm.h, to explain that there are two
ways to count pinned pages: exact (for compound pages of order > 1) and
fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages).
============================================================
General notes about the tracking patch:
This is a prerequisite to solving the problem of proper interactions
between file-backed pages, and [R]DMA activities, as discussed in [1],
[2], [3], [4] and in a remarkable number of email threads since about
2017. :)
In contrast to earlier approaches, the page tracking can be incrementally
applied to the kernel call sites that, until now, have been simply calling
get_user_pages() ("gup"). In other words, opt-in by changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
unpin_user_page()
============================================================
Future steps:
* Convert more subsystems from get_user_pages() to pin_user_pages().
The first probably needs to be bio/biovecs, because any filesystem
testing is too difficult without those in place.
* Change VFS and filesystems to respond appropriately when encountering
dma-pinned pages.
* Work with Ira and others to connect this all up with file system

[4] LWN kernel index: get_user_pages()
https://lwn.net/Kernel/Index/#Memory_management-get_user_pages
This patch (of 12):
An upcoming patch requires reusing the implementation of
get_user_pages_remote(). Split up get_user_pages_remote() into an outer
routine that checks flags, and an implementation routine that will be
reused. This makes subsequent changes much easier to understand.
There should be no change in behavior due to this patch.

argument through to the __gup_device_* functions.

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm: introduce page_ref_sub_return()
An upcoming patch requires subtracting a large chunk of refcounts from a
page, and checking what the resulting refcount is. This is a little
different than the usual "check for zero refcount" that many of the page
ref functions already do. However, it is similar to a few other routines
that (like this one) are generally useful for things such as 1-based
refcounting.
Add page_ref_sub_return(), that subtracts a chunk of refcounts atomically,
and returns an atomic snapshot of the result.

Subject: mm/gup: require FOLL_GET for get_user_pages_fast()
Internal to mm/gup.c, require that get_user_pages_fast() and
__get_user_pages_fast() identify themselves, by setting FOLL_GET. This is
required in order to be able to make decisions based on "FOLL_PIN, or
FOLL_GET, or both or neither are set", in upcoming patches.

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup: track FOLL_PIN pages
Add tracking of pages that were pinned via FOLL_PIN. This tracking is
implemented via overloading of page->_refcount: pins are added by adding
GUP_PIN_COUNTING_BIAS (1024) to the refcount. This provides a fuzzy
indication of pinning, and it can have false positives (and that's OK).
Please see the pre-existing Documentation/core-api/pin_user_pages.rst for
details.
As mentioned in pin_user_pages.rst, callers who effectively set FOLL_PIN
(typically via pin_user_pages*()) are required to ultimately free such
pages via unpin_user_page().
Please also note the limitation, discussed in pin_user_pages.rst under the
"TODO: for 1GB and larger huge pages" section. (That limitation will be
removed in a following patch.)
The effect of a FOLL_PIN flag is similar to that of FOLL_GET, and may be
thought of as "FOLL_GET for DIO and/or RDMA use".
Pages that have been pinned via FOLL_PIN are identifiable via a new
function call:
bool page_maybe_dma_pinned(struct page *page);
What to do in response to encountering such a page, is left to later
patchsets. There is discussion about this in [1], [2], [3], and [4].
This also changes a BUG_ON(), to a WARN_ON(), in follow_page_mask().

+ * GUP_PIN_COUNTING_BIAS, and the associated functions that use it, overload
+ * the page's refcount so that two separate items are tracked: the original page
+ * reference count, and also a new count of how many pin_user_pages() calls were
+ * made against the page. ("gup-pinned" is another term for the latter).
+ *
+ * With this scheme, pin_user_pages() becomes special: such pages are marked as
+ * distinct from normal pages. As such, the unpin_user_page() call (and its
+ * variants) must be used in order to release gup-pinned pages.
+ *
+ * Choice of value:
+ *
+ * By making GUP_PIN_COUNTING_BIAS a power of two, debugging of page reference
+ * counts with respect to pin_user_pages() and unpin_user_page() becomes
+ * simpler, due to the fact that adding an even power of two to the page
+ * refcount has the effect of using only the upper N bits, for the code that
+ * counts up using the bias value. This means that the lower bits are left for
+ * the exclusive use of the original code that increments and decrements by one
+ * (or at least, by much smaller values than the bias value).
+ *
+ * Of course, once the lower bits overflow into the upper bits (and this is
+ * OK, because subtraction recovers the original values), then visual inspection
+ * no longer suffices to directly view the separate counts. However, for normal
+ * applications that don't have huge page reference counts, this won't be an
+ * issue.

- * unpin_user_page(), or one of the unpin_user_pages*() routines. This is so
- * that eventually such pages can be separately tracked and uniquely handled. In
- * particular, interactions with RDMA and filesystems need special handling.
- *
- * unpin_user_page() and put_page() are not interchangeable, despite this early
- * implementation that makes them look the same. unpin_user_page() calls must
- * be perfectly matched up with pin*() calls.
+ * Locking: the lockless algorithm described in page_cache_get_speculative()

Subject: mm/gup: page->hpage_pinned_refcount: exact pin counts for huge pages
For huge pages (and in fact, any compound page), the GUP_PIN_COUNTING_BIAS
scheme tends to overflow too easily, each tail page increments the head
page->_refcount by GUP_PIN_COUNTING_BIAS (1024). That limits the number
of huge pages that can be pinned.
This patch removes that limitation, by using an exact form of pin counting
for compound pages of order > 1. The "order > 1" is required because this
approach uses the 3rd struct page in the compound page, and order 1
compound pages only have two pages, so that won't work there.
A new struct page field, hpage_pinned_refcount, has been added, replacing
a padding field in the union (so no new space is used).
This enhancement also has a useful side effect: huge pages and compound
pages (of order > 1) do not suffer from the "potential false positives"
problem that is discussed in the page_dma_pinned() comment block. That is
because these compound pages have extra space for tracking things, so they
get exact pin counts instead of overloading page->_refcount.
Documentation/core-api/pin_user_pages.rst is updated accordingly.

For these pin_user_pages*() functions, FOLL_PIN is OR'd in with whatever gup
flags the caller provides. The caller is required to pass in a non-null struct
-pages* array, and the function then pin pages by incrementing each by a special
-value. For now, that value is +1, just like get_user_pages*().::
+pages* array, and the function then pins pages by incrementing each by a special
+value: GUP_PIN_COUNTING_BIAS.
+
+For huge pages (and in fact, any compound page of more than 2 pages), the
+GUP_PIN_COUNTING_BIAS scheme is not used. Instead, an exact form of pin counting
+is achieved, by using the 3rd struct page in the compound page. A new struct
+page field, hpage_pinned_refcount, has been added in order to support this.
+
+This approach for compound pages avoids the counting upper limit problems that
+are discussed below. Those limitations would have been aggravated severely by
+huge pages, because each tail page adds a refcount to the head page. And in
+fact, testing revealed that, without a separate hpage_pinned_refcount field,
+page overflows were seen in some huge page stress tests.
+
+This also means that huge pages and compound pages (of order > 1) do not suffer

-when pin_user_pages() follows such pages, it increments the head page by "1"

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup: /proc/vmstat: pin_user_pages (FOLL_PIN) reporting
Now that pages are "DMA-pinned" via pin_user_page*(), and unpinned via
unpin_user_pages*(), we need some visibility into whether all of this is
working correctly.
Add two new fields to /proc/vmstat:
nr_foll_pin_acquired
nr_foll_pin_released
These are documented in Documentation/core-api/pin_user_pages.rst. They
represent the number of pages (since boot time) that have been pinned
("nr_foll_pin_acquired") and unpinned ("nr_foll_pin_released"), via
pin_user_pages*() and unpin_user_pages*().
In the absence of long-running DMA or RDMA operations that hold pages
pinned, the above two fields will normally be equal to each other.
Also: update Documentation/core-api/pin_user_pages.rst, to remove an
earlier (now confirmed untrue) claim about a performance problem with
/proc/vmstat.
Also: update Documentation/core-api/pin_user_pages.rst to rename the new
/proc/vmstat entries, to the names listed here.

@@ -208,12 +208,35 @@ has the following new calls to exercise
You can monitor how many total dma-pinned pages have been acquired and released
since the system was booted, via two new /proc/vmstat entries: ::
- /proc/vmstat/nr_foll_pin_requested
- /proc/vmstat/nr_foll_pin_requested
+ /proc/vmstat/nr_foll_pin_acquired
+ /proc/vmstat/nr_foll_pin_released
-Those are both going to show zero, unless CONFIG_DEBUG_VM is set. This is
-because there is a noticeable performance drop in unpin_user_page(), when they
-are activated.
+Under normal conditions, these two values will be equal unless there are any
+long-term [R]DMA pins in place, or during pin/unpin transitions.
+
+* nr_foll_pin_acquired: This is the number of logical pins that have been
+ acquired since the system was powered on. For huge pages, the head page is
+ pinned once for each page (head page and each tail page) within the huge page.
+ This follows the same sort of behavior that get_user_pages() uses for huge
+ pages: the head page is refcounted once for each tail or head page in the huge
+ page, when get_user_pages() is applied to a huge page.
+
+* nr_foll_pin_released: The number of logical pins that have been released since
+ the system was powered on. Note that pages are released (unpinned) on a
+ PAGE_SIZE granularity, even if the original pin was applied to a huge page.
+ Becaused of the pin count behavior described above in "nr_foll_pin_acquired",
+ the accounting balances out, so that after doing this::
+
+ pin_user_pages(huge_page);
+ for (each page in huge_page)
+ unpin_user_page(page);
+
+...the following is expected::
+
+ nr_foll_pin_released == nr_foll_pin_acquired
+
+(...unless it was already out of balance due to a long-term RDMA pin being in
+place.)

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup_benchmark: support pin_user_pages() and related calls
Up until now, gup_benchmark supported testing of the following kernel
functions:
* get_user_pages(): via the '-U' command line option
* get_user_pages_longterm(): via the '-L' command line option
* get_user_pages_fast(): as the default (no options required)
Add test coverage for the new corresponding pin_*() functions:
* pin_user_pages_fast(): via the '-a' command line option
* pin_user_pages(): via the '-b' command line option
Also, add an option for clarity: '-u' for what is now (still) the default
choice: get_user_pages_fast().
Also, for the commands that set FOLL_PIN, verify that the pages really are
dma-pinned, via the new is_dma_pinned() routine. Those commands are:
PIN_FAST_BENCHMARK : calls pin_user_pages_fast()
PIN_BENCHMARK : calls pin_user_pages()
In between the calls to pin_*() and unpin_user_pages(), check each page:
if page_maybe_dma_pinned() returns false, then WARN and return.
Do this outside of the benchmark timestamps, so that it doesn't affect
reported times.

From: John Hubbard <jhubbard@nvidia.com>
Subject: selftests/vm: run_vmtests: invoke gup_benchmark with basic FOLL_PIN coverage
It's good to have basic unit test coverage of the new FOLL_PIN behavior.
Fortunately, the gup_benchmark unit test is extremely fast (a few
milliseconds), so adding it the the run_vmtests suite is going to cause no
noticeable change in running time.
So, add two new invocations to run_vmtests:
1) Run gup_benchmark with normal get_user_pages().
2) Run gup_benchmark with pin_user_pages(). This is much like the
first call, except that it sets FOLL_PIN.
Running these two in quick succession also provide a visual comparison of
the running times, which is convenient.
The new invocations are fairly early in the run_vmtests script, because
with test suites, it's usually preferable to put the shorter, faster tests
first, all other things being equal.

From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
Subject: mm: improve dump_page() for compound pages
There was no protection against a corrupted struct page having an
implausible compound_head(). Sanity check that a compound page has a head
within reach of the maximum allocatable page (this will need to be
adjusted if one of the plans to allocate 1GB pages comes to fruition). In
addition,
- Print the mapping pointer using %p insted of %px. The actual value of
the pointer can be read out of the raw page dump and using %p gives a
chance to correlate it with an earlier printk of the mapping pointer
- Print the mapping pointer from the head page, not the tail page
(the tail ->mapping pointer may be in use for other purposes, eg part
of a list_head)
- Print the order of the page for compound pages
- Dump the raw head page as well as the raw page
- Print the refcount from the head page, not the tail page

Subject: mm: dump_page(): additional diagnostics for huge pinned pages
As part of pin_user_pages() and related API calls, pages are "dma-pinned".
For the case of compound pages of order > 1, the per-page accounting of
dma pins is accomplished via the 3rd struct page in the compound page. In
order to support debugging of any pin_user_pages()- related problems,
enhance dump_page() so as to report the pin count in that case.
Documentation/core-api/pin_user_pages.rst is also updated accordingly.

Subject: mm/zswap: allow setting default status, compressor and allocator in Kconfig
The compressed cache for swap pages (zswap) currently needs from 1 to 3
extra kernel command line parameters in order to make it work: it has to
be enabled by adding a "zswap.enabled=1" command line parameter and if one
wants a different compressor or pool allocator than the default lzo / zbud
combination then these choices also need to be specified on the kernel
command line in additional parameters.
Using a different compressor and allocator for zswap is actually pretty
common as guides often recommend using the lz4 / z3fold pair instead of
the default one. In such case it is also necessary to remember to enable
the appropriate compression algorithm and pool allocator in the kernel
config manually.
Let's avoid the need for adding these kernel command line parameters and
automatically pull in the dependencies for the selected compressor
algorithm and pool allocator by adding an appropriate default switches to
Kconfig.
The default values for these options match what the code was using
previously as its defaults.

Subject: hugetlb_cgroup: add hugetlb_cgroup reservation counter
These counters will track hugetlb reservations rather than hugetlb memory
faulted in. This patch only adds the counter, following patches add the
charging and uncharging of the counter.
This is patch 1 of an 9 patch series.
Problem:
Currently tasks attempting to reserve more hugetlb memory than is
available get a failure at mmap/shmget time. This is thanks to Hugetlbfs
Reservations [1]. However, if a task attempts to reserve more hugetlb
memory than its hugetlb_cgroup limit allows, the kernel will allow the
mmap/shmget call, but will SIGBUS the task when it attempts to fault in
the excess memory.
We have users hitting their hugetlb_cgroup limits and thus we've been
looking at this failure mode. We'd like to improve this behavior such
that users violating the hugetlb_cgroup limits get an error on mmap/shmget
time, rather than getting SIGBUS'd when they try to fault the excess
memory in. This gives the user an opportunity to fallback more gracefully
to non-hugetlbfs memory for example.
The underlying problem is that today's hugetlb_cgroup accounting happens
at hugetlb memory *fault* time, rather than at *reservation* time. Thus,
enforcing the hugetlb_cgroup limit only happens at fault time, and the
offending task gets SIGBUS'd.
Proposed Solution:
A new page counter named
'hugetlb.xMB.rsvd.[limit|usage|max_usage]_in_bytes'. This counter has
slightly different semantics than
'hugetlb.xMB.[limit|usage|max_usage]_in_bytes':
- While usage_in_bytes tracks all *faulted* hugetlb memory,
rsvd.usage_in_bytes tracks all *reserved* hugetlb memory and hugetlb
memory faulted in without a prior reservation.
- If a task attempts to reserve more memory than limit_in_bytes allows,
the kernel will allow it to do so. But if a task attempts to reserve
more memory than rsvd.limit_in_bytes, the kernel will fail this
reservation.
This proposal is implemented in this patch series, with tests to verify
functionality and show the usage.
Alternatives considered:
1. A new cgroup, instead of only a new page_counter attached to the
existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code
duplication with hugetlb_cgroup. Keeping hugetlb related page counters
under hugetlb_cgroup seemed cleaner as well.
2. Instead of adding a new counter, we considered adding a sysctl that
modifies the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do
accounting at reservation time rather than fault time. Adding a new
page_counter seems better as userspace could, if it wants, choose to
enforce different cgroups differently: one via limit_in_bytes, and
another via rsvd.limit_in_bytes. This could be very useful if you're
transitioning how hugetlb memory is partitioned on your system one
cgroup at a time, for example. Also, someone may find usage for both
limit_in_bytes and rsvd.limit_in_bytes concurrently, and this approach
gives them the option to do so.
Testing:
- Added tests passing.
- Used libhugetlbfs for regression testing.

Subject: hugetlb_cgroup: add interface for charge/uncharge hugetlb reservations
Augments hugetlb_cgroup_charge_cgroup to be able to charge hugetlb usage
or hugetlb reservation counter.
Adds a new interface to uncharge a hugetlb_cgroup counter via
hugetlb_cgroup_uncharge_counter.
Integrates the counter with hugetlb_cgroup, via hugetlb_cgroup_init,
hugetlb_cgroup_have_usage, and hugetlb_cgroup_css_offline.

Subject: hugetlb_cgroup: add reservation accounting for private mappings
Normally the pointer to the cgroup to uncharge hangs off the struct page,
and gets queried when it's time to free the page. With hugetlb_cgroup
reservations, this is not possible. Because it's possible for a page to
be reserved by one task and actually faulted in by another task.
The best place to put the hugetlb_cgroup pointer to uncharge for
reservations is in the resv_map. But, because the resv_map has different
semantics for private and shared mappings, the code patch to
charge/uncharge shared and private mappings is different. This patch
implements charging and uncharging for private mappings.
For private mappings, the counter to uncharge is in
resv_map->reservation_counter. On initializing the resv_map this is set
to NULL. On reservation of a region in private mapping, the tasks
hugetlb_cgroup is charged and the hugetlb_cgroup is placed is
resv_map->reservation_counter.
On hugetlb_vm_op_close, we uncharge resv_map->reservation_counter.

Subject: hugetlb: disable region_add file_region coalescing
A follow up patch in this series adds hugetlb cgroup uncharge info the
file_region entries in resv->regions. The cgroup uncharge info may differ
for different regions, so they can no longer be coalesced at region_add
time. So, disable region coalescing in region_add in this patch.
Behavior change:
Say a resv_map exists like this [0->1], [2->3], and [5->6].
Then a region_chg/add call comes in region_chg/add(f=0, t=5).
Old code would generate resv->regions: [0->5], [5->6].
New code would generate resv->regions: [0->1], [1->2], [2->3], [3->5],
[5->6].
Special care needs to be taken to handle the resv->adds_in_progress
variable correctly. In the past, only 1 region would be added for every
region_chg and region_add call. But now, each call may add multiple
regions, so we can no longer increment adds_in_progress by 1 in
region_chg, or decrement adds_in_progress by 1 after region_add or
region_abort. Instead, region_chg calls add_reservation_in_range() to
count the number of regions needed and allocates those, and that info is
passed to region_add and region_abort to decrement adds_in_progress
correctly.
We've also modified the assumption that region_add after region_chg never
fails. region_chg now pre-allocates at least 1 region for region_add. If
region_add needs more regions than region_chg has allocated for it, then
it may fail.

From: Mina Almasry <almasrymina@google.com>
Subject: hugetlb_cgroup: add accounting for shared mappings
For shared mappings, the pointer to the hugetlb_cgroup to uncharge lives
in the resv_map entries, in file_region->reservation_counter.
After a call to region_chg, we charge the approprate hugetlb_cgroup, and
if successful, we pass on the hugetlb_cgroup info to a follow up
region_add call. When a file_region entry is added to the resv_map via
region_add, we put the pointer to that cgroup in
file_region->reservation_counter. If charging doesn't succeed, we report
the error to the caller, so that the kernel fails the reservation.
On region_del, which is when the hugetlb memory is unreserved, we also
uncharge the file_region->reservation_counter.

Subject: hugetlb_cgroup: support noreserve mappings
Support MAP_NORESERVE accounting as part of the new counter.
For each hugepage allocation, at allocation time we check if there is a
reservation for this allocation or not. If there is a reservation for
this allocation, then this allocation was charged at reservation time, and
we don't re-account it. If there is no reserevation for this allocation,
we charge the appropriate hugetlb_cgroup.
The hugetlb_cgroup to uncharge for this allocation is stored in
page[3].private. We use new APIs added in an earlier patch to set this
pointer.

From: Mina Almasry <almasrymina@google.com>
Subject: hugetlb: support file_region coalescing again
An earlier patch in this series disabled file_region coalescing in order
to hang the hugetlb_cgroup uncharge info on the file_region entries.
This patch re-adds support for coalescing of file_region entries.
Essentially everytime we add an entry, we call a recursive function that
tries to coalesce the added region with the regions next to it. The worst
case call depth for this function is 3: one to coalesce with the region
next to it, one to coalesce to the region prev, and one to reach the base
case.
This is an important performance optimization as private mappings add
their entries page by page, and we could incur big performance costs for
large mappings with lots of file_region entries in their resv_map.

Subject: hugetlb_cgroup: add hugetlb_cgroup reservation tests
The tests use both shared and private mapped hugetlb memory, and monitors
the hugetlb usage counter as well as the hugetlb reservation counter.
They test different configurations such as hugetlb memory usage via
hugetlbfs, or MAP_HUGETLB, or shmget/shmat, and with and without
MAP_POPULATE.
Also add test for hugetlb reservation reparenting, since this is a subtle
issue.

+1. Page fault accounting
+
+hugetlb.<hugepagesize>.limit_in_bytes
+hugetlb.<hugepagesize>.max_usage_in_bytes
+hugetlb.<hugepagesize>.usage_in_bytes
+hugetlb.<hugepagesize>.failcnt
+
+The HugeTLB controller allows users to limit the HugeTLB usage (page fault) per
+control group and enforces the limit during page fault. Since HugeTLB
+doesn't support page reclaim, enforcing the limit at page fault time implies
+that, the application will get SIGBUS signal if it tries to fault in HugeTLB
+pages beyond its limit. Therefore the application needs to know exactly how many
+HugeTLB pages it uses before hand, and the sysadmin needs to make sure that
+there are enough available on the machine for all the users to avoid processes
+getting SIGBUS.
+
+
+2. Reservation accounting
+
+hugetlb.<hugepagesize>.rsvd.limit_in_bytes
+hugetlb.<hugepagesize>.rsvd.max_usage_in_bytes
+hugetlb.<hugepagesize>.rsvd.usage_in_bytes
+hugetlb.<hugepagesize>.rsvd.failcnt
+
+The HugeTLB controller allows to limit the HugeTLB reservations per control
+group and enforces the controller limit at reservation time and at the fault of
+HugeTLB memory for which no reservation exists. Since reservation limits are
+enforced at reservation time (on mmap or shget), reservation limits never causes
+the application to get SIGBUS signal if the memory was reserved before hand. For
+MAP_NORESERVE allocations, the reservation limit behaves the same as the fault
+limit, enforcing memory usage at fault time and causing the application to
+receive a SIGBUS if it's crossing its limit.
+
+Reservation limits are superior to page fault limits described above, since
+reservation limits are enforced at reservation time (on mmap or shget), and
+never causes the application to get SIGBUS signal if the memory was reserved
+before hand. This allows for easier fallback to alternatives such as
+non-HugeTLB memory for example. In the case of page fault accounting, it's very
+hard to avoid processes getting SIGBUS since the sysadmin needs precisely know
+the HugeTLB usage of all the tasks in the system and make sure there is enough
+pages to satisfy all requests. Avoiding tasks getting SIGBUS on overcommited
+systems is practically impossible with page fault accounting.
+
+
+3. Caveats with shared memory
+
+For shared HugeTLB memory, both HugeTLB reservation and page faults are charged
+to the first task that causes the memory to be reserved or faulted, and all
+subsequent uses of this reserved or faulted memory is done without charging.
+
+Shared HugeTLB memory is only uncharged when it is unreserved or deallocated.
+This is usually when the HugeTLB file is deleted, and not when the task that
+caused the reservation or fault has exited.
+
+
+4. Caveats with HugeTLB cgroup offline.
+
+When a HugeTLB cgroup goes offline with some reservations or faults still
+charged to it, the behavior is as follows:
+
+- The fault charges are charged to the parent HugeTLB cgroup (reparented),
+- the reservation charges remain on the offline HugeTLB cgroup.
+
+This means that if a HugeTLB cgroup gets offlined while there is still HugeTLB
+reservations charged to it, that cgroup persists as a zombie until all HugeTLB
+reservations are uncharged. HugeTLB reservations behave in this manner to match
+the memory controller whose cgroups also persist as zombie until all charged
+memory is uncharged. Also, the tracking of HugeTLB reservations is a bit more
+complex compared to the tracking of HugeTLB faults, so it is significantly

Subject: lib/bch.c: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language extension
to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning in
case the flexible array does not occur last in the structure, which will
help us prevent some kind of undefined behavior bugs from being
inadvertenly introduced[3] to the codebase from now on.
This issue was found with the help of Coccinelle.

flush_tlb_batched_pending() is under PTL but the write is not, but
mm->tlb_flush_batched is only a bool type, so the value is unlikely to be
shattered. Thus, mark it as an intentional data race by using the data
race macro.

Since the write is under pool->lock but the read is done as lockless.
Even though the commit 5b990546e334 ("mempool: fix and document
synchronization and memory barrier usage") introduced the smp_wmb() and
smp_rmb() pair to improve the situation, it is adequate to protect it
from data races which could lead to a logic bug, so fix it by adding
READ_ONCE() for the read.

crc32() will dereference object->pointer. If a shattered value was
returned due to a data race, it will be corrected in the next scan. Thus,
annotate it as an intentional data race using the data_race() macro.

Subject: mm: adjust shuffle code to allow for future coalescing
Patch series "mm / virtio: Provide support for free page reporting", v17.
This series provides an asynchronous means of reporting free guest pages
to a hypervisor so that the memory associated with those pages can be
dropped and reused by other processes and/or guests on the host. Using
this it is possible to avoid unnecessary I/O to disk and greatly improve
performance in the case of memory overcommit on the host.
When enabled we will be performing a scan of free memory every 2 seconds
while pages of sufficiently high order are being freed. In each pass at
least one sixteenth of each free list will be reported. By doing this we
avoid racing against other threads that may be causing a high amount of
memory churn.
The lowest page order currently scanned when reporting pages is
pageblock_order so that this feature will not interfere with the use of
Transparent Huge Pages in the case of virtualization.
Currently this is only in use by virtio-balloon however there is the hope
that at some point in the future other hypervisors might be able to make
use of it. In the virtio-balloon/QEMU implementation the hypervisor is
currently using MADV_DONTNEED to indicate to the host kernel that the page
is currently free. It will be zeroed and faulted back into the guest the
next time the page is accessed.
To track if a page is reported or not the Uptodate flag was repurposed and
used as a Reported flag for Buddy pages. We walk though the free list
isolating pages and adding them to the scatterlist until we either
encounter the end of the list or have processed at least one sixteenth of
the pages that were listed in nr_free prior to us starting. If we fill
the scatterlist before we reach the end of the list we rotate the list so
that the first unreported page we encounter is moved to the head of the
list as that is where we will resume after we have freed the reported
pages back into the tail of the list.
Below are the results from various benchmarks. I primarily focused on two
tests. The first is the will-it-scale/page_fault2 test, and the other is
a modified version of will-it-scale/page_fault1 that was enabled to use
THP. I did this as it allows for better visibility into different parts
of the memory subsystem. The guest is running with 32G for RAM on one
node of a E5-2630 v3. The host has had some features such as CPU turbo
disabled in the BIOS.

shuffle w/ RFC 16 8767010.50 0.32% 3199874.00 0.71%
The results above are for a baseline with a linux-next-20191219 kernel,
that kernel with this patch set applied but page reporting disabled in
virtio-balloon, the patches applied and page reporting fully enabled, the
patches enabled with page shuffling enabled, and the patches applied with
page shuffling enabled and an RFC patch that makes used of MADV_FREE in
QEMU. These results include the deviation seen between the average value
reported here versus the high and/or low value. I observed that during
the test memory usage for the first three tests never dropped whereas with
the patches fully enabled the VM would drop to using only a few GB of the
host's memory when switching from memhog to page fault tests.
Any of the overhead visible with this patch set enabled seems due to page
faults caused by accessing the reported pages and the host zeroing the
page before giving it back to the guest. This overhead is much more
visible when using THP than with standard 4K pages. In addition page
shuffling seemed to increase the amount of faults generated due to an
increase in memory churn. The overehad is reduced when using MADV_FREE as
we can avoid the extra zeroing of the pages when they are reintroduced to
the host, as can be seen when the RFC is applied with shuffling enabled.
The overall guest size is kept fairly small to only a few GB while the
test is running. If the host memory were oversubscribed this patch set
should result in a performance improvement as swapping memory in the host
can be avoided.
A brief history on the background of free page reporting can be found at:
https://lore.kernel.org/lkml/29f43d5796feed0dec8e8bb98b187d9dac03b900.camel@linux.intel.com/
This patch (of 9):
Move the head/tail adding logic out of the shuffle code and into the
__free_one_page function since ultimately that is where it is really
needed anyway. By doing this we should be able to reduce the overhead and
can consolidate all of the list addition bits in one spot.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>
Subject: mm: use zone and order instead of free area in free_list manipulators
In order to enable the use of the zone from the list manipulator functions
I will need access to the zone pointer. As it turns out most of the
accessors were always just being directly passed &zone->free_area[order]
anyway so it would make sense to just fold that into the function itself
and pass the zone and order as arguments instead of the free area.
In order to be able to reference the zone we need to move the declaration
of the functions down so that we have the zone defined before we define
the list manipulation functions. Since the functions are only used in the
file mm/page_alloc.c we can just move them there to reduce noise in the
header.

Subject: mm: add function __putback_isolated_page
There are cases where we would benefit from avoiding having to go through
the allocation and free cycle to return an isolated page.
Examples for this might include page poisoning in which we isolate a page
and then put it back in the free list without ever having actually
allocated it.
This will enable us to also avoid notifiers for the future free page
reporting which will need to avoid retriggering page reporting when
returning pages that have been reported on.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>
Subject: mm: introduce Reported pages
In order to pave the way for free page reporting in virtualized
environments we will need a way to get pages out of the free lists and
identify those pages after they have been returned. To accomplish this,
this patch adds the concept of a Reported Buddy, which is essentially
meant to just be the Uptodate flag used in conjunction with the Buddy page
type.
To prevent the reported pages from leaking outside of the buddy lists I
added a check to clear the PageReported bit in the del_page_from_free_list
function. As a result any reported page that is split, merged, or
allocated will have the flag cleared prior to the PageBuddy value being
cleared.
The process for reporting pages is fairly simple. Once we free a page
that meets the minimum order for page reporting we will schedule a worker
thread to start 2s or more in the future. That worker thread will begin
working from the lowest supported page reporting order up to MAX_ORDER - 1
pulling unreported pages from the free list and storing them in the
scatterlist.
When processing each individual free list it is necessary for the worker
thread to release the zone lock when it needs to stop and report the full
scatterlist of pages. To reduce the work of the next iteration the worker
thread will rotate the free list so that the first unreported page in the
free list becomes the first entry in the list.
It will then call a reporting function providing information on how many
entries are in the scatterlist. Once the function completes it will
return the pages to the free area from which they were allocated and start
over pulling more pages from the free areas until there are no longer
enough pages to report on to keep the worker busy, or we have processed as
many pages as were contained in the free area when we started processing
the list.
The worker thread will work in a round-robin fashion making its way though
each zone requesting reporting, and through each reportable free list
within that zone. Once all free areas within the zone have been processed
it will check to see if there have been any requests for reporting while
it was processing. If so it will reschedule the worker thread to start up
again in roughly 2s and exit.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>
Subject: virtio-balloon: pull page poisoning config out of free page hinting
Currently the page poisoning setting wasn't being enabled unless free page
hinting was enabled. However we will need the page poisoning tracking
logic as well for free page reporting. As such pull it out and make it a
separate bit of config in the probe function.
In addition we need to add support for the more recent init_on_free
feature which expects a behavior similar to page poisoning in that we
expect the page to be pre-zeroed.

Subject: virtio-balloon: add support for providing free page reports to host
Add support for the page reporting feature provided by virtio-balloon.
Reporting differs from the regular balloon functionality in that is is
much less durable than a standard memory balloon. Instead of creating a
list of pages that cannot be accessed the pages are only inaccessible
while they are being indicated to the virtio interface. Once the
interface has acknowledged them they are placed back into their respective
free lists and are once again accessible by the guest system.
Unlike a standard balloon we don't inflate and deflate the pages. Instead
we perform the reporting, and once the reporting is completed it is
assumed that the page has been dropped from the guest and will be faulted
back in the next time the page is accessed.

Subject: mm/page_reporting: rotate reported pages to the tail of the list
Rather than walking over the same pages again and again to get to the
pages that have yet to be reported we can save ourselves a significant
amount of time by simply rotating the list so that when we have a full
list of reported pages the head of the list is pointing to the next
non-reported page. Doing this should save us some significant time when
processing each free list.
This doesn't gain us much in the standard case as all of the non-reported
pages should be near the top of the list already. However in the case of
page shuffling this results in a noticeable improvement. Below are the
will-it-scale page_fault1 w/ THP numbers for 16 tasks with and without
this patch.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>
Subject: mm/page_reporting: add budget limit on how many pages can be reported per pass
In order to keep ourselves from reporting pages that are just going to be
reused again in the case of heavy churn we can put a limit on how many
total pages we will process per pass. Doing this will allow the worker
thread to go into idle much more quickly so that we avoid competing with
other threads that might be allocating or freeing pages.
The logic added here will limit the worker thread to no more than one
sixteenth of the total free pages in a given area per list. Once that
limit is reached it will update the state so that at the end of the pass
we will reschedule the worker to try again in 2 seconds when the memory
churn has hopefully settled down.
Again this optimization doesn't show much of a benefit in the standard
case as the memory churn is minmal. However with page allocator shuffling
enabled the gain is quite noticeable. Below are the results with a THP
enabled version of the will-it-scale page_fault1 test showing the
improvement in iterations for 16 processes or threads.

Subject: mm/page_reporting: add free page reporting documentation
Add documentation for free page reporting. Currently the only consumer is
virtio-balloon, however it is possible that other drivers might make use
of this so it is best to add a bit of documetation explaining at a high
level how to use the API.

+
+=====================
+Free Page Reporting
+=====================
+
+Free page reporting is an API by which a device can register to receive
+lists of pages that are currently unused by the system. This is useful in
+the case of virtualization where a guest is then able to use this data to
+notify the hypervisor that it is no longer using certain pages in memory.
+
+For the driver, typically a balloon driver, to use of this functionality
+it will allocate and initialize a page_reporting_dev_info structure. The
+field within the structure it will populate is the "report" function
+pointer used to process the scatterlist. It must also guarantee that it can
+handle at least PAGE_REPORTING_CAPACITY worth of scatterlist entries per
+call to the function. A call to page_reporting_register will register the
+page reporting interface with the reporting framework assuming no other
+page reporting devices are already registered.
+
+Once registered the page reporting API will begin reporting batches of
+pages to the driver. The API will start reporting pages 2 seconds after
+the interface is registered and will continue to do so 2 seconds after any
+page of a sufficiently high order is freed.
+
+Pages reported will be stored in the scatterlist passed to the reporting
+function with the final entry having the end bit set in entry nent - 1.
+While pages are being processed by the report function they will not be
+accessible to the allocator. Once the report function has been completed
+the pages will be returned to the free area from which they were obtained.
+
+Prior to removing a driver that is making use of free page reporting it
+is necessary to call page_reporting_unregister to have the
+page_reporting_dev_info structure that is currently in use by free page
+reporting removed. Doing this will prevent further reports from being
+issued via the interface. If another driver or the same driver is
+registered it is possible for it to resume where the previous driver had
+left off in terms of reporting free pages.

Since watermark could be compared or set to garbage due to a data race
which would change the code logic, fix it by adding a pair of READ_ONCE()
and WRITE_ONCE() in those places.
The "failcnt" counter is tolerant of some degree of inaccuracy and is only
used to report stats, a data race will not be harmful, thus mark it as an
intentional data race using the data_race() macro.

had memcg->memsw->watermark been accessed concurrently as reported by
KCSAN,

Since watermark could be compared or set to garbage due to load or store
tearing which would change the code logic, fix it by adding a pair of
READ_ONCE() and WRITE_ONCE() in those places.

The warning is almost impossible to trigger according to the commit
82f71ae4a2b8 ("mm: catch memory commitment underflow") but leave it for
now to catch any possible unbalanced vm_unacct_memory() in the future.
Since only the read is operating as lockless, mark it as an intentional
data race using the data_race() macro to avoid modifying
percpu_counter_read() and still catch unintended races elsewhere.

Generated files are also checked by sparse that's why add newline to
remove sparse (C=1) warning.
The issue was found on Microblaze and reported like this:
./arch/microblaze/include/generated/uapi/asm/unistd_32.h:438:45: warning:
no newline at end of file
Mips and PowerPC have it already but let's align with style used by m68k.

Subject: mm/filemap.c: don't bother dropping mmap_sem for zero size readahead
When handling a page fault, we drop mmap_sem to start async readahead so
that we don't block on IO submission with mmap_sem held. However there's
no point to drop mmap_sem in case readahead is disabled. Handle that case
to avoid pointless dropping of mmap_sem and retrying the fault. This was
actually reported to block mlockall(MCL_CURRENT) indefinitely.

Subject: mm/memcontrol.c: allocate shrinker_map on appropriate NUMA node
The shrinker_map may be touched from any cpu (e.g., a bit there may be set
by a task running everywhere) but kswapd is always bound to specific node.
So allocate shrinker_map from the related NUMA node to respect its NUMA
locality. Also, this follows generic way we use for allocation of memcg's
per-node data.

------------------------------------------------------
From: David Hildenbrand <david@redhat.com>
Subject: drivers/base/memory.c: indicate all memory blocks as removable
We see multiple issues with the implementation/interface to compute
whether a memory block can be offlined (exposed via
/sys/devices/system/memory/memoryX/removable) and would like to simplify
it (remove the implementation).
1. It runs basically lockless. While this might be good for performance,
we see possible races with memory offlining that will require at least
some sort of locking to fix.
2. Nowadays, more false positives are possible. No arch-specific checks
are performed that validate if memory offlining will not be denied
right away (and such check will require locking). For example, arm64
won't allow to offline any memory block that was added during boot -
which will imply a very high error rate. Other archs have other
constraints.
3. The interface is inherently racy. E.g., if a memory block is
detected to be removable (and was not a false positive at that time),
there is still no guarantee that offlining will actually succeed. So
any caller already has to deal with false positives.
4. It is unclear which performance benefit this interface actually
provides. The introducing commit 5c755e9fd813 ("memory-hotplug: add
sysfs removable attribute for hotplug memory remove") mentioned
"A user-level agent must be able to identify which sections of
memory are likely to be removable before attempting the
potentially expensive operation."
However, no actual performance comparison was included.
Known users:
- lsmem: Will group memory blocks based on the "removable" property. [1]
- chmem: Indirect user. It has a RANGE mode where one can specify
removable ranges identified via lsmem to be offlined. However, it
also has a "SIZE" mode, which allows a sysadmin to skip the manual
"identify removable blocks" step. [2]
- powerpc-utils: Uses the "removable" attribute to skip some memory
blocks right away when trying to find some to
offline+remove. However, with ballooning enabled, it
already skips this information completely (because it
once resulted in many false negatives). Therefore, the
implementation can deal with false positives properly
already. [3]
According to Nathan Fontenot, DLPAR on powerpc is nowadays no longer
driven from userspace via the drmgr command (powerpc-utils). Nowadays
it's managed in the kernel - including onlining/offlining of memory
blocks - triggered by drmgr writing to /sys/kernel/dlpar. So the
affected legacy userspace handling is only active on old kernels. Only ve=
ry
old versions of drmgr on a new kernel (unlikely) might execute slower -
totally acceptable.
With CONFIG_MEMORY_HOTREMOVE, always indicating "removable" should not
break any user space tool. We implement a very bad heuristic now. Withou=
t
CONFIG_MEMORY_HOTREMOVE we cannot offline anything, so report
"not removable" as before.
Original discussion can be found in [4] ("[PATCH RFC v1] mm:
is_mem_section_removable() overhaul").
Other users of is_mem_section_removable() will be removed next, so that
we can remove is_mem_section_removable() completely.

Subject: mm/memory.c: refactor insert_page to prepare for batched-lock insert
Add helper methods for vm_insert_page()/insert_page() to prepare for
vm_insert_pages(), which batch-inserts pages to reduce spinlock operations
when inserting multiple consecutive pages into the user page table.
The intention of this patch-set is to reduce atomic ops for tcp zerocopy
receives, which normally hits the same spinlock multiple times
consecutively.

From: Arjun Roy <arjunroy@google.com>
Subject: net-zerocopy: use vm_insert_pages() for tcp rcv zerocopy
Use vm_insert_pages() for tcp receive zerocopy. Spin lock cycles (as
reported by perf) drop from a couple of percentage points to a fraction of
a percent. This results in a roughly 6% increase in efficiency, measured
roughly as zerocopy receive count divided by CPU utilization.
The intention of this patchset is to reduce atomic ops for tcp zerocopy
receives, which normally hits the same spinlock multiple times
consecutively.

Subject: add missing page_count() check to vm_insert_pages().
Add missing page_count() check to vm_insert_pages(), specifically inside
insert_page_in_batch_locked(). This was accidentally forgotten in the
original patchset.
See: https://marc.info/?l=linux-mm&m=158156166403807&w=2
The intention of this patch-set is to reduce atomic ops for tcp zerocopy
receives, which normally hits the same spinlock multiple times
consecutively.

Subject: mm/migrate.c: no need to check for i > start in do_pages_move()
Patch series "cleanup on do_pages_move()", v5.
The logic in do_pages_move() is a little mess for audience to read and has
some potential error on handling the return value. Especially there are
three calls on do_move_pages_to_node() and store_status() with almost the
same form.
This patch set tries to make the code a little friendly for audience by
consolidate the calls.
This patch (of 4):
At this point, we always have i >= start. If i == start, store_status()
will return 0. So we can drop the check for i > start.

Subject: mm/migrate.c: wrap do_move_pages_to_node() and store_status()
Usually, do_move_pages_to_node() and store_status() are used in
combination. We have three similar call sites.
Let's provide a wrapper for both function calls -
move_pages_and_store_status - to make the calling code easier to maintain
and fix (as noted by Yang Shi, the return value handling of
do_move_pages_to_node() has a flaw).

From: Wei Yang <richardw.yang@linux.intel.com>
Subject: mm/migrate.c: unify "not queued for migration" handling in do_pages_move()
It can currently happen that we store the status of a page twice:
* Once we detect that it is already on the target node
* Once we moved a bunch of pages, and a page that's already on the
target node is contained in the current interval.
Let's simplify the code and always call do_move_pages_to_node() in case we
did not queue a page for migration. Note that pages that are already on
the target node are not added to the pagelist and are, therefore, ignored
by do_move_pages_to_node() - there is no functional change.
The status of such a page is now only stored once.

From: Yang Shi <yang.shi@linux.alibaba.com>
Subject: mm/migrate.c: migrate PG_readahead flag
Currently the migration code doesn't migrate PG_readahead flag.
Theoretically this would incur slight performance loss as the application
might have to ramp its readahead back up again. Even though such problem
happens, it might be hidden by something else since migration is typically
triggered by compaction and NUMA balancing, any of which should be more
noticeable.
Migrate the flag after end_page_writeback() since it may clear PG_reclaim
flag, which is the same bit as PG_readahead, for the new page.

From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
Subject: include: Remove highmem.h from pagemap.h
pagemap.h doesn't need highmem.h itself. Only two dozen users were
relying on pagemap to pull in highmem (usually for kmap), so fix them all
up and we can remove this header file dependency.

crc32() will dereference object->pointer. If a shattered value was
returned due to a data race, it will be corrected in the next scan.
scan_block() will dereference a range of addresses (e.g., percpu sections)
to search for valid pointers. Even if a data race heppens, it will cause
no issue because the code here does not care about the exact value of a
non-pointer. Thus, mark them as intentional data races using the
data_race() macro.

crc32() will dereference object->pointer. If a shattered value was
returned due to a data race, it will be corrected in the next scan. Thus,
annotate it as an intentional data race using the data_race() macro.

From: John Hubbard <jhubbard@nvidia.com>
Subject: checkpatch: support "base-commit:" format
In order to support the get-lore-mbox.py tool described in [1], I ran:
git format-patch --base=<commit> --cover-letter <revrange>
... which generated a "base-commit: <commit-hash>" tag at the end of the
cover letter. However, checkpatch.pl generated an error upon encounting
"base-commit:" in the cover letter:
"ERROR: Please use git commit description style..."
... because it found the "commit" keyword, and failed to recognize that
it was part of the "base-commit" phrase, and as such, should not be
subjected to the same commit description style rules.
Update checkpatch.pl to include a special case for "base-commit:" (at the
start of the line, possibly with some leading whitespace) so that that tag
no longer generates a checkpatch error.

commit 294f69e662d1 ("compiler_attributes.h: Add 'fallthrough' pseudo
keyword for switch/case use") added the pseudo keyword so add a test for
it to checkpatch.
Warn on a patch or use --strict for files.

From: Alexandru Ardelean <alexandru.ardelean@analog.com>
Subject: lib/string.c: update match_string() doc-strings with correct behavior
There were a few attempts at changing behavior of the match_string()
helpers (i.e. 'match_string()' & 'sysfs_match_string()'), to change &
extend the behavior according to the doc-string.
But the simplest approach is to just fix the doc-strings. The current
behavior is fine as-is, and some bugs were introduced trying to fix it.
As for extending the behavior, new helpers can always be introduced if
needed.
The match_string() helpers behave more like 'strncmp()' in the sense that
they go up to n elements or until the first NULL element in the array of
strings.
This change updates the doc-strings with this info.

------------------------------------------------------
From: Li Xinhai <lixinhai.lxh@gmail.com>
Subject: mm/mempolicy: support MPOL_MF_STRICT for huge page mapping
MPOL_MF_STRICT is used in mbind() for purposes:
(1) MPOL_MF_STRICT is set alone without MPOL_MF_MOVE or
MPOL_MF_MOVE_ALL, to check if there is misplaced page and return -EIO;
(2) MPOL_MF_STRICT is set with MPOL_MF_MOVE or MPOL_MF_MOVE_ALL, to
check if there is misplaced page which is failed to isolate, or page
is success on isolate but failed to move, and return -EIO.
For non hugepage mapping, (1) and (2) are implemented as expectation. For
hugepage mapping, (1) is not implemented. And in (2), the part about
failed to isolate and report -EIO is not implemented.
This patch implements the missed parts for hugepage mapping. Benefits
with it applied:
- User space can apply same code logic to handle mbind() on hugepage and
non hugepage mapping;
- Reliably using MPOL_MF_STRICT alone to check whether there is
misplaced page or not when bind policy on address range, especially for
address range which contains both hugepage and non hugepage mapping.
Analysis of potential impact to existing users:
- If MPOL_MF_STRICT alone was previously used, hugetlb pages not
following the memory policy would not cause an EIO error. After this
change, hugetlb pages are treated like all other pages. If
MPOL_MF_STRICT alone is used and hugetlb pages do not follow memory
policy an EIO error will be returned.
- For users who using MPOL_MF_STRICT with MPOL_MF_MOVE or
MPOL_MF_MOVE_ALL, the semantic about some pages could not be moved will
not be changed by this patch, because failed to isolate and failed to
move have same effects to users, so their existing code will not be
impacted.
In mbind man page, the note about 'MPOL_MF_STRICT is ignored on huge page
mappings' can be removed after this patch is applied.
Mike:
: The current behavior with MPOL_MF_STRICT and hugetlb pages is inconsistent
: and does not match documentation (as described above). The special
: behavior for hugetlb pages ideally should have been removed when hugetlb
: page migration was introduced. It is unlikely that anyone relies on
: today's inconsistent behavior, and removing one more case of special
: handling for hugetlb pages is a good thing.

Subject: mm/vmscan.c: don't round up scan size for online memory cgroup
commit 68600f623d69 ("mm: don't miss the last page because of round-off
error") makes the scan size round up to @denominator regardless of the
memory cgroup's state, online or offline. This affects the overall
reclaiming behavior: The corresponding LRU list is eligible for reclaiming
only when its size logically right shifted by @sc->priority is bigger than
zero in the former formula. For example, the inactive anonymous LRU list
should have at least 0x4000 pages to be eligible for reclaiming when we
have 60/12 for swappiness/priority and without taking scan/rotation ratio
into account. After the roundup is applied, the inactive anonymous LRU
list becomes eligible for reclaiming when its size is bigger than or equal
to 0x1000 in the same condition.
(0x4000 >> 12) * 60 / (60 + 140 + 1) = 1
((0x1000 >> 12) * 60) + 200) / (60 + 140 + 1) = 1
aarch64 has 512MB huge page size when the base page size is 64KB. The
memory cgroup that has a huge page is always eligible for reclaiming in
that case. The reclaiming is likely to stop after the huge page is
reclaimed, meaing the further iteration on @sc->priority and the silbing
and child memory cgroups will be skipped. The overall behaviour has been
changed. This fixes the issue by applying the roundup to offlined memory
cgroups only, to give more preference to reclaim memory from offlined
memory cgroup. It sounds reasonable as those memory is unlikedly to be
used by anyone.
The issue was found by starting up 8 VMs on a Ampere Mustang machine,
which has 8 CPUs and 16 GB memory. Each VM is given with 2 vCPUs and 2GB
memory. It took 264 seconds for all VMs to be completely up and 784MB
swap is consumed after that. With this patch applied, it took 236 seconds
and 60MB swap to do same thing. So there is 10% performance improvement
for my case. Note that KSM is disable while THP is enabled in the
testing.

The VM_BUG_ON() is already used by queue_pages_test_walk(), it sounds
better to dump more debug information by using VM_BUG_ON_VMA() to help
debugging.

Subject: drivers/base/memory.c: drop section_count
Patch series "mm: drop superfluous section checks when onlining/offlining".
Let's drop some superfluous section checks on the onlining/offlining path.
This patch (of 3):
Since commit c5e79ef561b0 ("mm/memory_hotplug.c: don't allow to
online/offline memory blocks with holes") we have a generic check in
offline_pages() that disallows offlining memory blocks with holes.
Memory blocks with missing sections are just another variant of these type
of blocks. We can stop checking (and especially storing) present
sections. A proper error message is now printed why offlining failed.
section_count was initially introduced in commit 07681215975e ("Driver
core: Add section count to memory_block struct") in order to detect when
it is okay to remove a memory block. It was used in commit 26bbe7ef6d5c
("drivers/base/memory.c: prohibit offlining of memory blocks with missing
sections") to disallow offlining memory blocks with missing sections. As
we refactored creation/removal of memory devices and have a proper check
for holes in place, we can drop the section_count.
This also removes a leftover comment regarding the mem_sysfs_mutex, which
was removed in commit 848e19ad3c33 ("drivers/base/memory.c: drop the
mem_sysfs_mutex").

From: David Hildenbrand <david@redhat.com>
Subject: drivers/base/memory.c: drop pages_correctly_probed()
pages_correctly_probed() is a leftover from ancient times. It dates back
to commit 3947be1969a9 ("[PATCH] memory hotplug: sysfs and add/remove
functions"), where Pg_reserved checks were added as a sfety net:
/*
* The probe routines leave the pages reserved, just
* as the bootmem code does. Make sure they're still
* that way.
*/
The checks were refactored quite a bit over the years, especially in
commit b77eab7079d9 ("mm/memory_hotplug: optimize probe routine"), where
checks for present, valid, and online sections were added.
Hotplugged memory is added via add_memory(), which will create the full
memmap for the hotplugged memory, and mark all sections valid and present.
Only full memory blocks are onlined/offlined, so we also cannot have an
inconsistency in that regard (especially, memory blocks with some sections
being online and some being offline).
1. Boot memory always starts online. Since commit c5e79ef561b0
("mm/memory_hotplug.c: don't allow to online/offline memory blocks with
holes") we disallow to offline any memory with holes. Therefore, we
never online memory with holes. Present and validity checks are
superfluous.
2. Only complete memory blocks are onlined/offlined (and especially,
the state - online or offline - is stored for whole memory blocks).
Besides the core, only arch/powerpc/platforms/powernv/memtrace.c
manually calls offline_pages() and fiddels with memory block states.
But it also only offlines complete memory blocks.
3. To make any of these conditions trigger, something would have to be
terribly messed up in the core. (e.g., online/offline only some
sections of a memory block).
4. Memory unplug properly makes sure that all sysfs attributes were
removed (and therefore, that all threads left the sysfs handlers). We
don't have to worry about zombie devices at this point.
5. The valid_section_nr(section_nr) check is actually dead code, as it
would never have been reached due to the WARN_ON_ONCE(!pfn_valid(pfn)).
No wonder we haven't seen any of these errors in a long time (or even
ever, according to my search). Let's just get rid of them. Now, all
checks that could hinder onlining and offlining are completely
contained in online_pages()/offline_pages().

The mm-of-the-moment snapshot 2020-02-13-22-26 has been uploaded to
http://www.ozlabs.org/~akpm/mmotm/
mmotm-readme.txt says
README for mm-of-the-moment:
http://www.ozlabs.org/~akpm/mmotm/
This is a snapshot of my -mm patch queue. Uploaded at random hopefully
more than once a week.
You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY). The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series
The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.
This tree is partially included in linux-next. To see which patches are
included in linux-next, consult the `series' file. Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.
A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release. Individual mmotm releases are tagged. The master branch always
points to the latest release, so it's constantly rebasing.
https://github.com/hnaz/linux-mm
The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree. It is updated more frequently
than mmotm, and is untested.
A git copy of this tree is also available at
https://github.com/hnaz/linux-mm
This mmotm tree contains the following patches against 5.6-rc1:
(patches marked "*" will be included in linux-next)

Andrew, you might want to remove those hugetlb cgroup patches from mmotm
as they are not yet fully reviewed and have some build issues.

Up to you guys but I just sent you a patch ("hugetlb: fix
CONFIG_CGROUP_HUGETLB ifdefs") that should fix this build issue.

Hi Mina,
I don't know if this was supposed to fix the 2 build reports that I made,
but this does not apply cleanly to mmotm (and it's a reply email so it's
more difficult to apply anyway):
Applying patch mm-hugetlb-fix-CONFIG_CGROUP_HUGETLB.patch
patching file mm/hugetlb.c
Hunk #1 succeeded at 289 with fuzz 1.

OK, I applied this patch manually and it does fix most of the reported build problems.
The only one remaining is this:

Hi Randy,
Yes this was supposed to fix the build errors. I'm having trouble
reproducing the one you have pending above. This is my development
environment:
➜ prodkernel2 git:(mm-build-fix) git remote show github-akpm
* remote github-akpm
Fetch URL: https://github.com/hnaz/linux-mm.git
Push URL: https://github.com/hnaz/linux-mm.git
➜ prodkernel2 git:(mm-build-fix) git s
## mm-build-fix...github-akpm/master [ahead 1]
➜ prodkernel2 git:(mm-build-fix) make -j80 mm/migrate.o
(succeeds with no warnings).
➜ prodkernel2 git:(mm-build-fix) make -j80
(succeeds with no warnings)
Is my development environment wrong? Shouldn't I be able to reproduce
this build warning on this tree with my fix?
https://github.com/hnaz/linux-mm.git
I'm using config-r9887 that you sent earlier.
I'm probably supposed to use a different branch since you also say
that my patch doesn't apply cleanily, but the mmotm readme says that
github mirrors Andrew's tree?

Just looking at the build error without being able to reproduce, it
looks like this diff would fix it?
➜ prodkernel2 git:(mm-build-fix) ✗ git diff
diff --git a/include/linux/hugetlb_cgroup.h b/include/linux/hugetlb_cgroup.h
index a09d4164ba910..5f66cdcbe9b10 100644
--- a/include/linux/hugetlb_cgroup.h
+++ b/include/linux/hugetlb_cgroup.h
@@ -15,6 +15,7 @@
#ifndef _LINUX_HUGETLB_CGROUP_H
#define _LINUX_HUGETLB_CGROUP_H
+#include <linux/hugetlb.h>
#include <linux/mmdebug.h>
struct hugetlb_cgroup;
Can you let me know? Or any insight into why I can't reproduce the
warning? Wrong tree perhaps?
I suspect a forward declaration of struct resv_map and struct
file_region in hugetlb_cgroup.h would also fix.

Just looking at the build error without being able to reproduce, it
looks like this diff would fix it?

Can you let me know? Or any insight into why I can't reproduce the
warning? Wrong tree perhaps?
I suspect a forward declaration of struct resv_map and struct
file_region in hugetlb_cgroup.h would also fix.

Hi Mina,
This patch does not fix the build warnings that I reported.
The initial report is here:
https://lore.kernel.org/lkml/97879032-f159-f1c6-9cde-d4e0389b2d7f@infradead.org/
and the kernel .config file is named config-r9883 (not r9887).

Yes, adding struct stubs in that header file does remove the
build warnings.
thanks.

The patch titled
Subject: mm/debug: add tests validating architecture page table helpers
has been added to the -mm tree. Its filename is
mm-debug-add-tests-validating-architecture-page-table-helpers.patch
This patch should soon appear at
http://ozlabs.org/~akpm/mmots/broken-out/mm-debug-add-tests-validating-architecture-page-table-helpers.patch
and later at
http://ozlabs.org/~akpm/mmotm/broken-out/mm-debug-add-tests-validating-architecture-page-table-helpers.patch
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm/debug: add tests validating architecture page table helpers
This adds tests which will validate architecture page table helpers and
other accessors in their compliance with expected generic MM semantics.
This will help various architectures in validating changes to existing
page table helpers or addition of new ones.
This test covers basic page table entry transformations including but not
limited to old, young, dirty, clean, write, write protect etc at various
level along with populating intermediate entries with next page table page
and validating them.
Test page table pages are allocated from system memory with required size
and alignments. The mapped pfns at page table levels are derived from a
real pfn representing a valid kernel text symbol. This test gets called
inside kernel_init() right after async_synchronize_full().
This test gets built and run when CONFIG_DEBUG_VM_PGTABLE is selected.
Any architecture, which is willing to subscribe this test will need to
select ARCH_HAS_DEBUG_VM_PGTABLE. For now this is limited to arc, arm64,
x86, s390 and ppc32 platforms where the test is known to build and run
successfully. Going forward, other architectures too can subscribe the
test after fixing any build or runtime problems with their page table
helpers. Meanwhile for better platform coverage, the test can also be
enabled with CONFIG_EXPERT even without ARCH_HAS_DEBUG_VM_PGTABLE.
Folks interested in making sure that a given platform's page table helpers
conform to expected generic MM semantics should enable the above config
which will just trigger this test during boot. Any non conformity here
will be reported as an warning which would need to be fixed. This test
will help catch any changes to the agreed upon semantics expected from
generic MM and enable platforms to accommodate it thereafter.

The patch titled
Subject: proc: faster open/read/close with "permanent" files
has been added to the -mm tree. Its filename is
proc-faster-open-read-close-with-permanent-files.patch
This patch should soon appear at
http://ozlabs.org/~akpm/mmots/broken-out/proc-faster-open-read-close-with-permanent-files.patch
and later at
http://ozlabs.org/~akpm/mmotm/broken-out/proc-faster-open-read-close-with-permanent-files.patch
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days

Subject: proc: faster open/read/close with "permanent" files
Now that "struct proc_ops" exist we can start putting there stuff which
could not fly with VFS "struct file_operations"...
Most of fs/proc/inode.c file is dedicated to make open/read/.../close
reliable in the event of disappearing /proc entries which usually happens
if module is getting removed. Files like /proc/cpuinfo which never
disappear simply do not need such protection.
Save 2 atomic ops, 1 allocation, 1 free per open/read/close sequence for such
"permanent" files.
Enable "permanent" flag for
/proc/cpuinfo
/proc/kmsg
/proc/modules
/proc/slabinfo
/proc/stat
/proc/sysvipc/*
/proc/swaps
More will come once I figure out foolproof way to prevent out module
authors from marking their stuff "permanent" for performance reasons
when it is not.
This should help with scalability: benchmark is "read /proc/cpuinfo R times
by N threads scattered over the system".

Subject: psi: move PF_MEMSTALL into psi specific psi_flags
The task->flags is a 32-bits flag, in which 31 bits have already been
consumed. So it is hard to introduce other new per process flags. As
there's a psi specific flag psi_flags, move the psi specific per process
flag PF_MEMSTALL into it.

The kernel we used is older, but we think the latest kernel also has this
bug after digging into this problem.
For 1G hugepages, huge_pte_offset() wants to return NULL or pudp, but it
may return a wrong 'pmdp' if there is a race. Please look at the
following code snippet:
...
pud = pud_offset(p4d, addr);
if (sz != PUD_SIZE && pud_none(*pud))
return NULL;
/* hugepage or swap? */
if (pud_huge(*pud) || !pud_present(*pud))
return (pte_t *)pud;
pmd = pmd_offset(pud, addr);
if (sz != PMD_SIZE && pmd_none(*pmd))
return NULL;
/* hugepage or swap? */
if (pmd_huge(*pmd) || !pmd_present(*pmd))
return (pte_t *)pmd;
...
The following sequence would trigger this bug:
1. CPU0: sz = PUD_SIZE and *pud = 0 , continue
1. CPU0: "pud_huge(*pud)" is false
2. CPU1: calling hugetlb_no_page and set *pud to xxxx8e7(PRESENT)
3. CPU0: "!pud_present(*pud)" is false, continue
4. CPU0: pmd = pmd_offset(pud, addr) and maybe return a wrong pmdp
However, we want CPU0 to return NULL or pudp.
We can avoid this race by reading the pud only once. What's more, we also
use READ_ONCE to access the entries for safety (i.e. avoid the compilier
mischief)

From: Mina Almasry <almasrymina@google.com>
Subject: hugetlb: remove check_coalesce_bug debug code
Commit b5f16a533ce8a ("hugetlb: support file_region coalescing again")
made changes to the resv_map code which are hard to test, it so added
debug code guarded by CONFIG_DEBUG_VM which conducts an expensive
operation that loops over the resv_map and checks it for errors.
Unfortunately, some distros have CONFIG_DEBUG_VM on in their default
kernels, and we don't want this debug code behind CONFIG_DEBUG_VM and
called each time a file region is added. This patch removes this debug
code. I may look into making it a test or leave it for my local testing.

When get an error in the middle of reading an inode, some fields in the
inode might be still not initialized. And then the evict_inode path may
access those fields via iput().
To fix, this makes sure that inode fields are initialized.

Don't allow resizing VMA as part of MREMAP_DONTUNMAP. There is no clear
use case at the moment and it can be added later as it simplifies the
implementation for now.

Subject: selftest: Add MREMAP_DONTUNMAP selftest.
Add a few simple self tests for the new flag MREMAP_DONTUNMAP,
they are simple smoke tests which also demonstrate the behavior.

The plain reads in try_to_unuse() are outside si->lock critical section
which result in data races that could be dangerous to be used in a loop.
Fix them by adding READ_ONCE().

The patch titled
Subject: psi: move PF_MEMSTALL into psi specific psi_flags
has been removed from the -mm tree. Its filename was

This patch was dropped because it was nacked

From: Yafang Shao <laoar.shao@gmail.com>
Subject: psi: move PF_MEMSTALL into psi specific psi_flags
The task->flags is a 32-bits flag, in which 31 bits have already been
consumed. So it is hard to introduce other new per process flags. As
there's a psi specific flag psi_flags, move the psi specific per process
flag PF_MEMSTALL into it.

rwlock.h should not be included directly. Instead linux/splinlock.h
should be included. One thing it does is to break the RT build.

From: Vlastimil Babka <vbabka@suse.cz>
Subject: mm, hotplug: fix page online with DEBUG_PAGEALLOC compiled but not enabled
Commit cd02cf1aceea ("mm/hotplug: fix an imbalance with DEBUG_PAGEALLOC")
fixed memory hotplug with debug_pagealloc enabled, where onlining a page
goes through page freeing, which removes the direct mapping. Some arches
don't like when the page is not mapped in the first place, so
generic_online_page() maps it first. This is somewhat wasteful, but
better than special casing page freeing fast paths.
The commit however missed that DEBUG_PAGEALLOC configured doesn't mean
it's actually enabled. One has to test debug_pagealloc_enabled() since
031bc5743f15 ("mm/debug-pagealloc: make debug-pagealloc boottime
configurable"), or alternatively debug_pagealloc_enabled_static() since
8e57f8acbbd1 ("mm, debug_pagealloc: don't rely on static keys too early"),
but this is not done.
As a result, a s390 kernel with DEBUG_PAGEALLOC configured but not enabled
will crash:

Fix this by checking debug_pagealloc_enabled_static() before calling
kernel_map_pages(). Backports for kernel before 5.5 should use
debug_pagealloc_enabled() instead. Also add comments.

Subject: mm/vma: add missing VMA flag readable name for VM_SYNC
Patch series "mm/vma: Use all available wrappers when possible", v2.
Apart from adding a VMA flag readable name for trace purpose, this series
does some open encoding replacements with availabe VMA specific wrappers.
This skips VM_HUGETLB check in vma_migratable() as its already being done
with another patch (https://patchwork.kernel.org/patch/11347831/) which is
yet to be merged.
This patch (of 4):
This just adds the missing readable name for VM_SYNC.

Subject: mm/vma: make vma_is_accessible() available for general use
Lets move vma_is_accessible() helper to include/linux/mm.h which makes it
available for general use. While here, this replaces all remaining open
encodings for VMA access check with vma_is_accessible().

Subject: mm/vma: append unlikely() while testing VMA access permissions
It is unlikely that an inaccessible VMA without required permission flags
will get a page fault. Hence lets just append unlikely() directive to
such checks in order to improve performance while also standardizing it
across various platforms.

From: Will Deacon <will@kernel.org>
Subject: samples/hw_breakpoint: drop HW_BREAKPOINT_R when reporting writes
Patch series "Unexport kallsyms_lookup_name() and kallsyms_on_each_symbol()".
Despite having just a single modular in-tree user that I could spot,
kallsyms_lookup_name() is exported to modules and provides a mechanism
for out-of-tree modules to access and invoke arbitrary, non-exported
kernel symbols when kallsyms is enabled.
This patch series fixes up that one user and unexports the symbol along
with kallsyms_on_each_symbol(), since that could also be abused in a
similar manner.
I would like to avoid out-of-tree modules being easily able to call
functions that are not exported. kallsyms_lookup_name() makes this
trivial to the point that there is very little incentive to rework these
modules to either use upstream interfaces correctly or propose
functionality which may be otherwise missing upstream. Both of these
latter solutions would be pre-requisites to upstreaming these modules, and
the current state of things actively discourages that approach.
The background here is that we are aiming for Android devices to be able
to use a generic binary kernel image closely following upstream, with any
vendor extensions coming in as kernel modules. In this case, we (Google)
end up maintaining the binary module ABI within the scope of a single LTS
kernel. Monitoring and managing the ABI surface is not feasible if it
effectively includes all data and functions via kallsyms_lookup_name().
Of course, we could just carry this patch in the Android kernel tree, but
we're aiming to carry as little as possible (ideally nothing) and I think
it's a sensible change in its own right. I'm surprised you object to it,
in all honesty.
Now, you could turn around and say "that's not upstream's problem", but it
still seems highly undesirable to me to have an upstream bypass for
exported symbols that isn't even used by upstream modules. It's ripe for
abuse and encourages people to work outside of the upstream tree. The
usual rule is that we don't export symbols without a user in the tree and
that seems especially relevant in this case.
This patch (of 3):
Given the name of a kernel symbol, the 'data_breakpoint' test claims to
"report any write operations on the kernel symbol". However, it creates
the breakpoint using both HW_BREAKPOINT_W and HW_BREAKPOINT_R, which menas
it also fires for read access.
Drop HW_BREAKPOINT_R from the breakpoint attributes.

Subject: samples/hw_breakpoint: drop use of kallsyms_lookup_name()
The 'data_breakpoint' test code is the only modular user of
kallsyms_lookup_name(), which was exported as part of fixing the test in
f60d24d2ad04 ("hw-breakpoints: Fix broken hw-breakpoint sample module").
In preparation for un-exporting this symbol, switch the test over to using
__symbol_get(), which can be used to place breakpoints on exported
symbols.

other policy. This patch series fixes this gap in accounting.
A simple script to demonstrate this behavior on cgroupv2 machine:
'''
#!/bin/bash
set -e
CGROUP=/sys/fs/cgroup/test.slice
LOOP_DEV=/dev/loop0
if [[ ! -d $CGROUP ]]
then
sudo mkdir $CGROUP
fi
grep oom_kill $CGROUP/memory.events
# Set a memory limit, write more than that limit to tmpfs -> OOM kill
sudo unshare -m bash -c "
echo \$\$ > $CGROUP/cgroup.procs;
echo 0 > $CGROUP/memory.swap.max;
echo 64M > $CGROUP/memory.max;
mount -t tmpfs -o size=512m tmpfs /tmp;
dd if=/dev/zero of=/tmp/file bs=1M count=256" || true
grep oom_kill $CGROUP/memory.events
# Set a memory limit, write more than that limit through loopback
# device -> no OOM kill
sudo unshare -m bash -c "
echo \$\$ > $CGROUP/cgroup.procs;
echo 0 > $CGROUP/memory.swap.max;
echo 64M > $CGROUP/memory.max;
mount -t tmpfs -o size=512m tmpfs /tmp;
truncate -s 512m /tmp/backing_file
losetup $LOOP_DEV /tmp/backing_file
dd if=/dev/zero of=$LOOP_DEV bs=1M count=256;
losetup -D $LOOP_DEV" || true
grep oom_kill $CGROUP/memory.events
'''
Naively charging cgroups could result in priority inversions through the
single kworker thread in the case where multiple cgroups are
reading/writing to the same loop device. This patch series does some
minor modification to the loop driver so that each cgroup can make forward
progress independently to avoid this inversion.
With this patch series applied, the above script triggers OOM kills when
writing through the loop device as expected.
This patch (of 3):
Existing uses of loop device may have multiple cgroups reading/writing to
the same device. Simply charging resources for I/O to the backing file
could result in priority inversion where one cgroup gets synchronously
blocked, holding up all other I/O to the loop device.
In order to avoid this priority inversion, we use a single workqueue where
each work item is a "struct loop_worker" which contains a queue of struct
loop_cmds to issue. The loop device maintains a tree mapping blk css_id
-> loop_worker. This allows each cgroup to independently make forward
progress issuing I/O to the backing file.
There is also a single queue for I/O associated with the rootcg which can
be used in cases of extreme memory shortage where we cannot allocate a
loop_worker.
The locking for the tree and queues is fairly heavy handed - we acquire
the per-loop-device spinlock any time either is accessed. The existing
implementation serializes all I/O through a single thread anyways, so I
don't believe this is any worse.

Subject: mm: charge active memcg when no mm is set
memalloc_use_memcg() worked for kernel allocations but was silently
ignored for user pages.
This patch establishes a precedence order for who gets charged:
1. If there is a memcg associated with the page already, that memcg is
charged. This happens during swapin.
2. If an explicit mm is passed, mm->memcg is charged. This happens
during page faults, which can be triggered in remote VMs (eg gup).
3. Otherwise consult the current process context. If it has configured
a current->active_memcg, use that. Otherwise, current->mm->memcg.
Previously, if a NULL mm was passed to mem_cgroup_try_charge (case 3) it
would always charge the root cgroup. Now it looks up the current
active_memcg first (falling back to charging the root cgroup if not set).

Subject: loop: charge i/o to mem and blk cg
The current code only associates with the existing blkcg when aio is used
to access the backing file. This patch covers all types of i/o to the
backing file and also associates the memcg so if the backing file is on
tmpfs, memory is charged appropriately.
This patch also exports cgroup_get_e_css so it can be used by the loop
module.

Subject: mm/mempolicy: check hugepage migration is supported by arch in vma_migratable()
vma_migratable() is called to check if pages in vma can be migrated before
go ahead to further actions. Currently it is used in below code path:
- task_numa_work
- mbind
- move_pages
For hugetlb mapping, whether vma is migratable or not is determined by:
- CONFIG_ARCH_ENABLE_HUGEPAGE_MIGRATION
- arch_hugetlb_migration_supported
Issue: current code only checks for CONFIG_ARCH_ENABLE_HUGEPAGE_MIGRATION
alone, and no code should use it directly. (note that current code in
vma_migratable don't cause failure or bug because
unmap_and_move_huge_page() will catch unsupported hugepage and handle it
properly)
This patch checks the two factors by hugepage_migration_supported for
impoving code logic and robustness. It will enable early bail out of
hugepage migration procedure, but because currently all architecture
supporting hugepage migration is able to support all page size, we would
not see performance gain with this patch applied.
vma_migratable() is moved to mm/mempolicy.c, because of the circular
reference of mempolicy.h and hugetlb.h cause defining it as inline not
feasible.

Subject: checkpatch: fix multiple const * types
Commit 1574a29f8e76 ("checkpatch: allow multiple const * types") claims to
support repetition of pattern "const *", but it actually allows only one
extra instance.
Check the following lines
int a(char const * const x[]);
int b(char const * const *x);
int c(char const * const * const x[]);
int d(char const * const * const *x);
with command
./scripts/checkpatch.pl --show-types -f filename
to find that only the first line passes the test, while a warning
is triggered by the other 3 lines:
WARNING:FUNCTION_ARGUMENTS: function definition argument
'char const * const' should also have an identifier name
The reason is that the pattern match halts at the second asterisk in the
line, thus the remaining text starting with asterisk fails to match a
valid name for a variable.
Fixed by replacing "?" (Match 1 or 0 times) with "{0,4}" (Match no more
than 4 times) in the regular expression. Fix also the similar test for
types in unusual order.

Subject: checkpatch: add command-line option for TAB size
Linux kernel coding style requires a size of 8 characters for both TAB and
indentation, and such value is embedded as magic value allover the
checkpatch script.
This makes hard to reuse the script by other projects with different
requirements in their coding style (e.g. OpenOCD [1] requires TAB size of
4 characters [2]).
Replace the magic value 8 with a variable.
Add a command-line option "--tab-size" to let the user select a
TAB size value other than 8.

Commit 30544ed5de43 ("lib/bitmap: introduce bitmap_replace() helper")
introduced some new test cases to the test_bitmap.c module. Among these
it also introduced an (unused) definition. Let's make use of
EXP2_IN_BITS.

From: Roman Gushchin <guro@fb.com>
Subject: mm: memcg/slab: introduce mem_cgroup_from_obj()
Sometimes we need to get a memcg pointer from a charged kernel object.
The right way to get it depends on whether it's a proper slab object or
it's backed by raw pages (e.g. it's a vmalloc alloction). In the first
case the kmem_cache->memcg_params.memcg indirection should be used; in
other cases it's just page->mem_cgroup.
To simplify this task and hide the implementation details let's introduce
a mem_cgroup_from_obj() helper, which takes a pointer to any kernel object
and returns a valid memcg pointer or NULL.
Passing a kernel address rather than a pointer to a page will allow to use
this helper for per-object (rather than per-page) tracked objects in the
future.
The caller is still responsible to ensure that the returned memcg isn't
going away underneath: take the rcu read lock, cgroup mutex etc; depending
on the context.
mem_cgroup_from_kmem() defined in mm/list_lru.c is now obsolete and can be
removed.

Subject: mm: kmem: cleanup (__)memcg_kmem_charge_memcg() arguments
Patch series "mm: memcg: kmem API cleanup", v2.
This patchset aims to clean up the kernel memory charging API. It doesn't
bring any functional changes, just removes unused arguments, renames some
functions and fixes some comments.
Currently it's not obvious which functions are most basic
(memcg_kmem_(un)charge_memcg()) and which are based on them
(memcg_kmem_(un)charge()). The patchset renames these functions and
removes unused arguments:
TL;DR:
was:
memcg_kmem_charge_memcg(page, gfp, order, memcg)
memcg_kmem_uncharge_memcg(memcg, nr_pages)
memcg_kmem_charge(page, gfp, order)
memcg_kmem_uncharge(page, order)
now:
memcg_kmem_charge(memcg, gfp, nr_pages)
memcg_kmem_uncharge(memcg, nr_pages)
memcg_kmem_charge_page(page, gfp, order)
memcg_kmem_uncharge_page(page, order)

The first argument of memcg_kmem_charge_memcg() and
__memcg_kmem_charge_memcg() is the page pointer and it's not used. Let's
drop it.
Memcg pointer is passed as the last argument. Move it to the first place
for consistency with other memcg functions, e.g.
__memcg_kmem_uncharge_memcg() or try_charge().

Subject: mm: kmem: cleanup memcg_kmem_uncharge_memcg() arguments
Drop the unused page argument and put the memcg pointer at the first
place. This make the function consistent with its peers:
__memcg_kmem_uncharge_memcg(), memcg_kmem_charge_memcg(), etc.

Subject: mm: kmem: switch to nr_pages in (__)memcg_kmem_charge_memcg()
These functions are charging the given number of kernel pages to the given
memory cgroup. The number doesn't have to be a power of two. Let's make
them to take the unsigned int nr_pages as an argument instead of the page
order.
It makes them look consistent with the corresponding uncharge functions
and functions like: mem_cgroup_charge_skmem(memcg, nr_pages).

Subject: mm: memcg/slab: cache page number in memcg_(un)charge_slab()
There are many places in memcg_charge_slab() and memcg_uncharge_slab()
which are calculating the number of pages to charge, css references to
grab etc depending on the order of the slab page.
Let's simplify the code by calculating it once and caching in the local
variable.

Subject: mm: kmem: rename (__)memcg_kmem_(un)charge_memcg() to __memcg_kmem_(un)charge()
Drop the _memcg suffix from (__)memcg_kmem_(un)charge functions. It's
shorter and more obvious.
These are the most basic functions which are just (un)charging the given
cgroup with the given amount of pages.
Also fix up the corresponding comments.

Subject: ocfs2: Add missing annotations for ocfs2_refcount_cache_lock() and ocfs2_refcount_cache_unlock()
Sparse reports warnings at ocfs2_refcount_cache_lock()
and ocfs2_refcount_cache_unlock()
warning: context imbalance in ocfs2_refcount_cache_lock()
- wrong count at exit
warning: context imbalance in ocfs2_refcount_cache_unlock()
- unexpected unlock
The root cause is the missing annotation at ocfs2_refcount_cache_lock()
and at ocfs2_refcount_cache_unlock()
Add the missing __acquires(&rf->rf_lock) annotation to
ocfs2_refcount_cache_lock()
Add the missing __releases(&rf->rf_lock) annotation to
ocfs2_refcount_cache_unlock()

The mm-of-the-moment snapshot 2020-02-24-19-53 has been uploaded to
http://www.ozlabs.org/~akpm/mmotm/
mmotm-readme.txt says
README for mm-of-the-moment:
http://www.ozlabs.org/~akpm/mmotm/
This is a snapshot of my -mm patch queue. Uploaded at random hopefully
more than once a week.
You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY). The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series
The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.
This tree is partially included in linux-next. To see which patches are
included in linux-next, consult the `series' file. Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.
A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release. Individual mmotm releases are tagged. The master branch always
points to the latest release, so it's constantly rebasing.
https://github.com/hnaz/linux-mm
The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree. It is updated more frequently
than mmotm, and is untested.
A git copy of this tree is also available at
https://github.com/hnaz/linux-mm
This mmotm tree contains the following patches against 5.6-rc3:

Subject: checkpatch: improve Gerrit Change-Id: test
The Gerrit Change-Id: entry is sometimes placed after a Signed-off-by:
line. When this occurs, the Gerrit warning is not currently emitted as
the first Signed-off-by: signature sets a flag to stop looking.
Change the test to add a test for the --- patch separator and emit the
warning before any before the --- and also before any diff file name.

Subject: dma-buf: free dmabuf->name in dma_buf_release()
dma-buff name can be set via DMA_BUF_SET_NAME ioctl, but once set
it never gets freed.

From: Vasily Averin <vvs@virtuozzo.com>
Subject: fs/seq_file.c: seq_read(): add info message about buggy .next functions
Patch series "seq_file .next functions should increase position index".
In Aug 2018 NeilBrown noticed commit 1f4aace60b0e ("fs/seq_file.c:
simplify seq_file iteration code and interface")
"Some ->next functions do not increment *pos when they return NULL...
Note that such ->next functions are buggy and should be fixed. A simple
demonstration is dd if=/proc/swaps bs=1000 skip=1 Choose any block size
larger than the size of /proc/swaps. This will always show the whole last
line of /proc/swaps"
Described problem is still actual. If you make lseek into middle of last
output line following read will output end of last line and whole last
line once again.
$ dd if=/proc/swaps bs=1 # usual output
Filename Type Size Used Priority
/dev/dm-0 partition 4194812 97536 -2
104+0 records in
104+0 records out
104 bytes copied
$ dd if=/proc/swaps bs=40 skip=1 # last line was generated twice
dd: /proc/swaps: cannot skip to specified offset

/dev/dm-0 partition 4194812 97536 -2
3+1 records in
3+1 records out
131 bytes copied
There are lot of other affected files, I've found 30+ including
/proc/net/ip_tables_matches and /proc/sysvipc/*
I've sent patches into maillists of affected subsystems already, this
patch-set fixes the problem in files related to pstore, tracing, gcov,
sysvipc and other subsystems processed via linux-kernel@ mailing list
directly
https://bugzilla.kernel.org/show_bug.cgi?id=206283
This patch (of 4):
Add debug code to seq_read() to detect missed or out-of-tree incorrect
.next seq_file functions.

Thanks for taking this patch via -mm during my absence (I'm just
returning from a bit of an illness). If there are other dma-buf
patches on your radar that you'd like to take via the mm tree, please
let me know and I can provide the necessary Acks.
Else I will take them in via drm-misc as usual.

I thought at least that for cases like these -mm is the last resort
tree, so proper thing to do here is apply this fix to drm-misc-fixes
and get it out there. -mm rebases, so will fall out again.
Also maybe we should have had some tests for this, plus some
integration with the gem object name instead of duplicating buffer
object names everywhere for different reasons.

From: Arjun Roy <arjunroy@google.com>
Subject: mm: bring sparc pte_index() semantics inline with other platforms
pte_index() on platforms other than sparc return a numerical index. On
sparc, it returns a pte_t*. This presents an issue for vm_insert_pages(),
which relies on pte_index() to find the offset for a pte within a pmd, for
batched inserts.
This patch:
1. Modifies pte_index() for sparc to return a numerical index, like
other platforms,
2. Defines pte_entry() for sparc which returns a pte_t*
(as pte_index() used to),
3. Converts existing sparc callers for pte_index() to use pte_entry().
[sfr@canb.auug.org.au: remove pte_entry and just directly modified pte_offset_kernel instead]

Subject: mm/vmscan.c: fix data races using kswapd_classzone_idx
pgdat->kswapd_classzone_idx could be accessed concurrently in
wakeup_kswapd(). Plain writes and reads without any lock protection
result in data races. Fix them by adding a pair of READ|WRITE_ONCE() as
well as saving a branch (compilers might well optimize the original code
in an unintentional way anyway). While at it, also take care of
pgdat->kswapd_order and non-kswapd threads in allow_direct_reclaim(). The
data races were reported by KCSAN,
BUG: KCSAN: data-race in wakeup_kswapd / wakeup_kswapd

Subject: fs/epoll: make nesting accounting safe for -rt kernel
Davidlohr Bueso pointed out that when CONFIG_DEBUG_LOCK_ALLOC is set
ep_poll_safewake() can take several non-raw spinlocks after disabling
interrupts. Since a spinlock can block in the -rt kernel, we can't take a
spinlock after disabling interrupts. So let's re-work how we determine
the nesting level such that it plays nicely with the -rt kernel.
Let's introduce a 'nests' field in struct eventpoll that records the
current nesting level during ep_poll_callback(). Then, if we nest again
we can find the previous struct eventpoll that we were called from and
increase our count by 1. The 'nests' field is protected by
ep->poll_wait.lock.
I've also moved the visited field to reduce the size of struct eventpoll
from 184 bytes to 176 bytes on x86_64 for !CONFIG_DEBUG_LOCK_ALLOC, which
is typical for a production config.

Subject: lib: optimize cpumask_local_spread()
In multi-processor and NUMA system, I/O driver will find cpu cores that
which shall be bound IRQ. When cpu cores in the local numa have been
used, it is better to find the node closest to the local numa node for
performance, instead of choosing any online cpu immediately.
On Huawei Kunpeng 920 server, there are 4 NUMA node(0 - 3) in the 2-cpu
system(0 - 1). The topology of this server is followed:
available: 4 nodes (0-3)
node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
node 0 size: 63379 MB
node 0 free: 61899 MB
node 1 cpus: 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47
node 1 size: 64509 MB
node 1 free: 63942 MB

node 3 size: 63997 MB

node distances:
node 0 1 2 3
0: 10 16 32 33

2: 32 25 10 16
3: 33 32 16 10
We perform PS (parameter server) business test, the behavior of the
service is that the client initiates a request through the network card,
the server responds to the request after calculation. When two PS
processes run on node2 and node3 separately and the network card is
located on 'node2' which is in cpu1, the performance of node2 (26W QPS)
and node3 (22W QPS) is different.
It is better that the NIC queues are bound to the cpu1 cores in turn, then
XPS will also be properly initialized, while cpumask_local_spread only
considers the local node. When the number of NIC queues exceeds the
number of cores in the local node, it returns to the online core directly.
So when PS runs on node3 sending a calculated request, the performance is
not as good as the node2.
The IRQ from 369-392 will be bound from NUMA node0 to NUMA node3 with this
patch, before the patch:
Euler:/sys/bus/pci # cat /proc/irq/369/smp_affinity_list
0
Euler:/sys/bus/pci # cat /proc/irq/370/smp_affinity_list
1
...
Euler:/sys/bus/pci # cat /proc/irq/391/smp_affinity_list
22
Euler:/sys/bus/pci # cat /proc/irq/392/smp_affinity_list
23
After the patch:
Euler:/sys/bus/pci # cat /proc/irq/369/smp_affinity_list
72
Euler:/sys/bus/pci # cat /proc/irq/370/smp_affinity_list
73
...
Euler:/sys/bus/pci # cat /proc/irq/391/smp_affinity_list
94
Euler:/sys/bus/pci # cat /proc/irq/392/smp_affinity_list
95
So the performance of the node3 is the same as node2 that is 26W QPS when
the network card is still in 'node2' with the patch.
It is considered that the NIC and other I/O devices shall initialize the
interrupt binding, if the cores of the local node are used up, it is
reasonable to return the node closest to it. Let's optimize it and find
the nearest node through NUMA distance for the non-local NUMA nodes.

Subject: mm-debug-add-tests-validating-architecture-page-table-helpers-fix
A warning gets exposed with DEBUG_VIRTUAL due to __pa() on a kernel symbol
i.e 'start_kernel' which might be outside the linear map. This happens
due to kernel mapping position randomization with KASLR.
__pa_symbol() should have been used instead, for accessing the physical
address here. On arm64 __pa() does check for linear address with
__is_lm_address() and switch accordingly if it is a kernel text symbol.
Nevertheless, its much better to use __pa_symbol() here rather than
__pa().

From: "Gustavo A. R. Silva" <gustavo@embeddedor.com>
Subject: gcov: gcc_4_7: replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language extension
to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning in
case the flexible array does not occur last in the structure, which will
help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by this
change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

Yup, go ahead. If a patch pops up in linux-next I'll autodrop by copy.
And please do give some thought to whether this should be cc:stable.

A warning gets exposed with DEBUG_VIRTUAL due to __pa() on a kernel symbol
i.e 'start_kernel' which might be outside the linear map. This happens
due to kernel mapping position randomization with KASLR.
__pa_symbol() should have been used instead, for accessing the physical
address here. On arm64 __pa() does check for linear address with
__is_lm_address() and switch accordingly if it is a kernel text symbol.
Nevertheless, its much better to use __pa_symbol() here rather than
__pa().

Subject: mm: huge tmpfs: try to split_huge_page() when punching hole
Yang Shi writes:
Currently, when truncating a shmem file, if the range is partly in a THP
(start or end is in the middle of THP), the pages actually will just get
cleared rather than being freed, unless the range covers the whole THP.
Even though all the subpages are truncated (randomly or sequentially), the
THP may still be kept in page cache.
This might be fine for some usecases which prefer preserving THP, but
balloon inflation is handled in base page size. So when using shmem THP
as memory backend, QEMU inflation actually doesn't work as expected since
it doesn't free memory. But the inflation usecase really needs to get the
memory freed. (Anonymous THP will also not get freed right away, but will
be freed eventually when all subpages are unmapped: whereas shmem THP
still stays in page cache.)
Split THP right away when doing partial hole punch, and if split fails
just clear the page so that read of the punched area will return zeroes.
Hugh Dickins adds:
Our earlier "team of pages" huge tmpfs implementation worked in the way
that Yang Shi proposes; and we have been using this patch to continue to
split the huge page when hole-punched or truncated, since converting over
to the compound page implementation. Although huge tmpfs gives out huge
pages when available, if the user specifically asks to truncate or punch a
hole (perhaps to free memory, perhaps to reduce the memcg charge), then
the filesystem should do so as best it can, splitting the huge page.
That is not always possible: any additional reference to the huge page
prevents split_huge_page() from succeeding, so the result can be flaky.
But in practice it works successfully enough that we've not seen any
problem from that.
Add shmem_punch_compound() to encapsulate the decision of when a split is
needed, and doing the split if so. Using this simplifies the flow in
shmem_undo_range(); and the first (trylock) pass does not need to do any
page clearing on failure, because the second pass will either succeed or
do that clearing. Following the example of zero_user_segment() when
clearing a partial page, add flush_dcache_page() and set_page_dirty() when
clearing a hole - though I'm not certain that either is needed.
But: split_huge_page() would be sure to fail if shmem_undo_range()'s
pagevec holds further references to the huge page. The easiest way to fix
that is for find_get_entries() to return early, as soon as it has put one
compound head or tail into the pagevec. At first this felt like a hack;
but on examination, this convention better suits all its callers - or will
do, if the slight one-page-per-pagevec slowdown in shmem_unlock_mapping()
and shmem_seek_hole_data() is transformed into a 512-page-per-pagevec
speedup by checking for compound pages there.

- A few misc subsystems
- There is a lot of MM material in Willy's tree. Folio work and
non-folio patches which depended on that work.
Here I send almost all the MM patches which precede the patches in
Willy's tree. The remaining ~100 MM patches are staged on Willy's
tree and I'll send those along once Willy is merged up.
I tried this batch against your current tree (as of
51912904076680281) and a couple need some extra persuasion to apply,
but all looks OK otherwise.

So this *completely* flummoxed 'b4', because you first sent the wrong
series, and then sent the right one in the same thread.
I fetched the emails manually, but honestly, this was confusing even
then, with two "[PATCH x/5]" series where the only way to tell the
right one was basically by date of email. They did arrive in the same
order in my mailbox, but even that wouldn't have been guaranteed if
there had been some mailer delays somewhere..
So next time when you mess up, resend it all as a completely new
series and completely new threading - so with a new header email too.
Please?
And since I'm here, let me just verify that yes, the series you
actually want me to apply is this one (as described by the head
email):

Crap, sorry, ignore all this, shall redo tomorrow.

are identical to the v6 posting [1] and git version [2] that Mel and
Mike tested (replies to [1]).

No, unless my bisection is wrong, the -mm branch is innocent, and was
discarded from the suspects on the very first bisection trial.
So never mind.

I haven't bisected this yet, but with the current -git I'm getting
watchdog: BUG: soft lockup - CPU#41 stuck for 49s!
and the common call chain seems to be in flush_tlb_mm_range ->
on_each_cpu_cond_mask.
Commit e058a84bfddc42ba356a2316f2cf1141974625c9 is good, and looking
at the pulls and merges I've done since, this -mm series looks like
the obvious culprit.
I'll go start bisection, but I thought I'd give a heads-up in case
somebody else has seen TLB-flush-related lockups and already figured
out the guilty party..

Oh, much too late for this release by now.

5.13-rc1 is two days from now, it would be for 5.14-rc1.. How time -
and version numbers - fly.

This is everything else from -mm for this merge window, with the
possible exception of Mike Rapoport's "secretmem" syscall patch series
(https://lkml.kernel.org/r/20210303162209.8609-1-rppt@kernel.org).
I've been wobbly about the secretmem patches due to doubts about
whether the feature is sufficiently useful to justify inclusion, but
developers are now weighing in with helpful information and I've asked Mike
for an extensively updated [0/n] changelog. This will take a few days
to play out so it is possible that I will prevail upon you for a post-rc1
merge. If that's a problem, there's always 5.13-rc1.
91 patches, based on 8ca5297e7e38f2dc8c753d33a5092e7be181fff0, plus
previously sent patches.
Thanks.

Yeah these patches faced problem from the very beginning getting
into the MM/LKML list for some strange reason.

It's weird. They don't turn up on linux-mm either, and that's running
at kvack.org, also majordomo. They don't get through when sent with
either heirloom-mailx or with sylpheed.
Also, it seems that when Anshuman originally sent the patch, linux-mm
and linux-kernel didn't send it back out. So perhaps a spam filter
triggered?
I'm seeing
https://lore.kernel.org/linux-arm-kernel/1615278790-18053-3-git-send-email-anshuman.khandual@arm.com/
which is via linux-arm-kernel@lists.infradead.org but the linux-kernel
server massacred that patch series. Searching
https://lkml.org/lkml/2021/3/9 for "anshuman" only shows 3 of the 7
email series.
One of the emails (as sent my me) is attached, if that helps.

Subject: [patch 103/143] mm: generalize SYS_SUPPORTS_HUGETLBFS (rename as ARCH_SUPPORTS_HUGETLBFS)
Message-ID: <20210505031626.c8o4WL7KE%akpm@linux-foundation.org>
In-Reply-To: <20210504183219.a3cc46aee4013d77402276c5@linux-foundation.org>
User-Agent: s-nail v14.8.16
X-Gm-Original-To: akpm@linux-foundation.org
From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm: generalize SYS_SUPPORTS_HUGETLBFS (rename as ARCH_SUPPORTS_HUGETLBFS)
SYS_SUPPORTS_HUGETLBFS config has duplicate definitions on platforms that
subscribe it. Instead, just make it a generic option which can be
selected on applicable platforms. Also rename it as
ARCH_SUPPORTS_HUGETLBFS instead. This reduces code duplication and makes
it cleaner.

Well, you re-sent it twice, and I have three copies in my own mailbox,
bot they still don't show up on the mm-commits mailing list.
So the list hates them for some odd reason.
I've picked them up locally, but adding Konstantin to the participants
to see if he can see what's up.
Konstantin: patches 103/106/107 are missing on lore out of Andrew's
series of 143. Odd.

Well that's strange. I see all three via cc:me, but not on linux-mm or
mm-commits.
Let me resend right now with the same in-reply-to. Hopefully they will

Hmm. Only 140 seem to have made it to the list, with 103, 106 and 107 missing.
Maybe just some mail delay? But at least right now
https://lore.kernel.org/mm-commits/
doesn't show them (and thus 'b4' doesn't work).
I'll check again later.

Just to clarify: you have nothing else really pending?
I'm hoping to just do -rc1 this weekend after all - despite my late

I'll allow late stragglers with good reason through, but the fewer of
those there are, the better, of course.
Thanks,
Linus

- The rest of MM.
Includes kfence - another runtime memory validator. Not as
thorough as KASAN, but it has unmeasurable overhead and is intended
to be usable in production builds.

I'm not sure why that patch surfaced the bug, but it's worth pointing
out that the underlying problem is asan-stack in combination
with the structleak plugin. This will happen for every user of kunit.
I sent a series[1] out earlier this year to turn off the structleak
plugin as an alternative workaround, but need to follow up on
the remaining patches. Someone suggested adding a more
generic way to turn off the plugin for a file instead of open-coding
the CLFAGS_REMOVE_*.o Makefile bit, which would help.
I am also still hoping that someone can come up with a way
to make kunit work better with the structleak plugin, as there
shouldn't be a fundamental reason why it can't work, just that
it the code pattern triggers a particularly bad case in the compiler.

A quick bisect shoes that this was introduced by "[patch 101/173]
kasan: remove redundant config option".
I didn't check what part of that patch screws up, but it's definitely
doing something bad.
I will drop that patch.

Hmm. I haven't bisected things yet, but I suspect it's something with
the KASAN patches. With this all applied, I get:
lib/crypto/curve25519-hacl64.c: In function ‘ladder_cmult.constprop’:

which is obviously not really acceptable. A 11kB stack frame _will_
cause issues.

Hah. This series shows a small deficiency in your scripting wrt the diffstat:

It actually has 18 files changed, but one of them is a pure rename (no
change to the content), and apparently your diffstat tool can't handle
that case.
It *should* have ended with
...
mm/slub.c | 18 +++++-
.../selftests/vm/{run_vmtests => run_vmtests.sh} | 0
18 files changed, 172 insertions(+), 49 deletions(-)
rename tools/testing/selftests/vm/{run_vmtests => run_vmtests.sh} (100%)
if you'd done a proper "git diff -M --stat --summary" of the series.
[ Ok, by default git would actually have said
18 files changed, 171 insertions(+), 48 deletions(-)
but it looks like you use the patience diff option, which gives that
extra insertion/deletion line because it generates the diff a bit
differently ]
Not a big deal,, but it made me briefly wonder "why doesn't my
diffstat match yours".

Whee. I had completely dropped the ball on this - I had built my usual
"akpm" branch with the patches, but then had completely forgotten
about it after doing my basic build tests.
I tend to leave it for a while to see if people send belated ACK/NAK's
for the patches, but that "for a while" is typically "overnight", not
several days.
So if you ever notice that I haven't merged your patch submission, and
you haven't seen me comment on them, feel free to ping me to remind
me.
Because it might just have gotten lost in the shuffle for some random
reason. Admittedly it's rare - I think this is the first time I just
randomly noticed three days later that I'd never done the actual merge
of the patch-series).

I see that you enabled renaming in the patches. Lovely.
Can you also enable it in the diffstat?
> 74 files changed, 2869 insertions(+), 1553 deletions(-)
With -M in the diffstat, you should have seen
72 files changed, 2775 insertions(+), 1460 deletions(-)
and if you add "--summary", you'll also see the rename part ofthe file
create/delete summary:
rename mm/kasan/{tags_report.c => report_sw_tags.c} (78%)
which is often nice to see in addition to the line stats..

oop, sorry, yes, the "based on" thing was wrong because I had two
series in flight simultaneously. I've never tried that before..

Yes, then it applies cleanly. So apparently we just have different
concepts of what really constitutes a "base" for applying your series.

With your re-send, I get all patches, but they don't actually apply cleanly.
Is that base correct?
I get
error: patch failed: mm/huge_memory.c:2750
error: mm/huge_memory.c: patch does not apply
Patch failed at 0004 mm/thp: narrow lru locking
for that patch "[patch 04/19] mm/thp: narrow lru locking", and that's
definitely true: the patch fragment has
@@ -2750,7 +2751,7 @@ int split_huge_page_to_list(struct page
__dec_lruvec_page_state(head, NR_FILE_THPS);

- __split_huge_page(page, list, end, flags);
+ __split_huge_page(page, list, end);
ret = 0;
} else {
if (IS_ENABLED(CONFIG_DEBUG_VM) && mapcount) {
but that __dec_lruvec_page_state() conversion was done by your
previous commit series.
So I have the feeling that what you actually mean by "base" isn't
actually really the base for that series at all..
I will try to apply it on top of my merge of your previous series instead.

I'm not seeing patch 10/19 at all.
And patch 19/19 is corrupted and has an attachment with a '^P'
character in it. I could fix it up, but with the missing patch in the
middle I'm not going to even try. 'b4' is also very unhappy about that
patch 19/19.
I don't know what went wrong, but I'll ignore this send - please
re-send the series at your leisure, ok?

It's a bug in b4 that I overlooked. Public-inbox emits mboxrd-formatted
.mbox files, while Python's mailbox.mbox consumes mboxo only. The main
distinction between the two is precisely that mboxrd will convert
">From " into ">>From " in an attempt to avoid corruption during
escape/unescape (it didn't end up fixing the problem 100% and mostly
introduced incompatibilities like this one).
I have a fix in master/stable-0.6.y and I'll release a 0.6.2 before the
end of the week.
Thanks for the report.

Hmm. It looks like that patch is the only one in the series with the
">From" marker in the commit message, from the silly "clarify that
this isn't the first line in a new message in mbox format".
And "b4 am" has turned the single ">" into two, making the stupid
marker worse, and actually corrupting the end result.
Coincidence? Or cause?

Hmm. It looks like that patch is the only one in the series with the
">From" marker in the commit message, from the silly "clarify that
this isn't the first line in a new message in mbox format".
And "b4 am" has turned the single ">" into two, making the stupid
marker worse, and actually corrupting the end result.

I haven't actually processed the patches yet, but I have a question
for Konstantin wrt b4.
All the patches except for _one_ get a nice little green check-mark
next to them when I use 'git am' on this series.
The one that did not was [patch 192/200].
I have no idea why - and it doesn't matter a lot to me, it just stood
out as being different. I'm assuming Andrew has started doing patch
attestation, and that patch failed. But if so, maybe Konstantin wants
to know what went wrong.
Konstantin?

Note that I've picked them up the old-fashioned way, so don't re-send them.
So more of a note for "please, next time..."

You didn't cc lkml, so now none of the nice 'b4' automation seems to

been caught that way?

The local_lock merge made rather a mess of all of this. I'm
cooking up a full resend of the same material.

I'm actually used to diffstats not matching 100%/
Usually it's not due to this issue - a "git diff --stat" *will* give
the stat from the actual combined diff result - but with git diffstats
the issue is that I might have gotten a patch from another source.
So the diffstat I see after-the-merge is possibly different from the
pre-merge diffstat simply due to merge issues.
So then I usually take a look at "ok, why did that diffstat differ"
and go "Ahh".
In your case, when I looked at the diffstat, I couldn't for the life
of me see how you would have gotten the diffstat you did, since I only
saw a single patch with no merge issues.
> Thanks for spotting it.

I can also just live with it, knowing what your workflow is. The
diffstat matching exactly just isn't that important - in fact,
different versions of "diff" can give slightly different output anyway
depending on diff algorithms even when they are looking at the exact
same before/after state. There's not necessarily always only one way
to generate a valid diff.
So to me, the diffstat is more of a guide than a hard thing, and I
want to see the rough outline,
In fact, one reason I want to see it in pull requests is actually just
that I want to get a feel for what changes even before I do the pull
or merge, so it's not just a "match against what I get" thing.

Stupid diffstat. Means that basically all my diffstats are very wrong.
Thanks for spotting it.
I can fix that...

Ahh. Yes - given two patches, diffstat just adds up the line number
counts for the individual diffs, it doesn't count some kind of
"combined diff result" line counts.

Bah. I got lazy (didn't want to interrupt an ongoing build) so I
generated the diffstat prior to folding two patches into a single one.
Evidently diffstat isn't as smart as I had assumed!

I wonder how you generate that diffstat.
The change to <linux/mm.h> simply doesn't match what you sent me. The
patch you sent me that changed mm.h had this:
include/linux/mm.h | 15 +++++++++++++--
1 file changed, 13 insertions(+), 2 deletions(-)
(note 15 lines changed: it's +13 and -2) but now suddenly in your

with +15/-4.
So your diffstat simply doesn't match what you are sending. What's going on?

Once/if there is such tool, could it perhaps instead of mass e-mailing create
git commits, push them to korg repo and send a pull request?

Side note: I've obviously picked it up the old-fashioned way, but I
had been looking forward to seeing if I could just automate this more.

This is correct -- each patch is posted without an in-reply-to, so
public-inbox doesn't group them into a thread.
E.g.:

Andrew, I'll be happy to provide you with a helper tool if you can
describe me your workflow. E.g. if you have a quilt directory of patches
plus a series file, it could easily be a tiny wrapper like:
send-patches --base-commit 1234abcd --cover cover.txt patchdir/series

Hmm. Konstantin's nice lore script _used_ to pick up your patches, but
now they don't.
I'm not sure what changed. It worked with your big series of 118 patches.
It doesn't work with this smaller series of fixes.
I think the difference is that you've done something bad to your patch
sending. That big series was properly threaded with each of the
patches being a reply to the 'incoming' message.
This series is not.
Please, Andrew, can you make your email flow more consistent so that I
can actually use the nice new tool to download a patch series?

Sorry about this, I'll try to track down the cause of this and hopefully
resubmit for 5.6.

I've dropped these, and since they clearly weren't ready I don't want
to see them re-sent for 5.5.
If somebody figures out the bug, trying again for 5.6 sounds fine.

Hey, Andrew, would it be at all possible for you to thread these
patches under something like this incoming message? The selfish reason
I'm asking is so I can mark the thread as read instead of having to do
it individually for 158 messages ... my thumb would thank you for this.
Regards,
James

- a small number of updates to scripts/, ocfs2 and fs/buffer.c
- most of MM. I still have quite a lot of material (mostly not MM)
staged after linux-next due to -next dependencies. I'll send thos
across next week as the preprequisites get merged up.

The usual shower of hotfixes.
Chris's memcg patches aren't actually fixes - they're mature but a few
niggling review issues were late to arrive.
The ocfs2 fixes are quite old - those took some time to get
reviewer attention.

All I am saying is that I am not able to wrap my head around this patch
to provide a competent Ack. I also believe that the fix is targetting a
wrong layer of the problem as explained in my review feedback. Appart
from reclaim/compaction interaction mentioned by Vlastimil, it seems
that it is an overly eager fallback to a remote node in the fast path
that is causing a large part of the problem as well. Kcompactd is not
eager enough to keep high order allocations ready for the fast path.
This is not specific to THP we have many other high order allocations
which are going to follow the same pattern, likely not visible in any
counters but still having performance implications.
Let's discuss technical details in the respective email thread

I believe we found a problem when investigating over-reclaim in this
thread [1] where it seems madvised THP allocation attempt can result in
4MB reclaimed, if there is a small zone such as ZONE_DMA on the node. As
it happens, the patch "[patch 090/134] mm, reclaim: make
should_continue_reclaim perform dryrun detection" in Andrew's pile
should change this 4MB to 32 pages reclaimed (as a side-effect), but
that has to be tested. I'm also working on a patch to not reclaim even
those few pages. Of course there might be more fundamental issues with
reclaim/compaction interaction, but this one seems to become hopefully
clear now.

The thing is, that's not an argument when we know that the current
state is garbage and has a lot of these non-trivial side effects that
are bad.
So the patch by David _fixes_ a non-trivial bad side effect.
You can't then say "there may be other non-trivial side effects that I
don't even know about" as an argument for saying it's bad. David at
least has numbers and an argument for his patch.

The patch proposed by David is really non trivial wrt. potential side
effects. I have provided my review feedback [1] and it didn't get
any reaction. I really believe that we need to debug this properly. A
reproducer would be useful for others to work on that.
There is a more fundamental problem here and we need to address it
rather than to duck tape it and whack a mole afterwards.

Confused. I saw a privately emailed patch from David which nobody
seems to have tested yet. I parked that for consideration after -rc1.
Or are you referring to something else?
This thing keeps stalling. It would be nice to push this along and get
something nailed down which we can at least get into 5.4-rc, perhaps
with a backport-this tag?

Thanks for that!
Perhaps now it would be nice if this went also to linux-mm and lkml, as
mm-commits is sort of hidden.

Very much agree, that was also discussed at length in the LSF/MM mm
process session I've linked.

I'll check if the first patch bomb would be more amenable to that, as I
plan to fill in the mm part for 5.3 on LinuxChanges wiki, but for a
merge commit it's too late.

Nevermind the misc stuff that much, but I think mm itself is more
important and deserves what other subsystems have.

I put all pid{fd}/clone{3} which is mostly related to pid.c, exit.c,
fork.c into my tree and try to give it a consistent theme for the prs I
sent. And that at least from my perspective that worked and was pretty
easy to coordinate with Andrew. That should hopefully make it a little
easier to theme the -mm tree overall going forward.

Hi,
as I've mentioned at LSF/MM [1], I think it would be nice if mm pull
requests had summaries similar to other subsystems. I see they are now
more structured (thanks!), but they are now probably hitting the limit
of what scripting can do to produce a high-level summary for human
readers (unless patch authors themselves provide a blurb that can be
extracted later?).
So I've tried now to provide an example what I had in mind, below. Maybe
it's too concise - if there were "larger" features in this pull request,
they would probably benefit from more details. I'm CCing the known (to
me) consumers of these mails to judge :) Note I've only covered mm, and
core stuff that I think will be interesting to wide audience (change in
LIST_POISON2 value? I'm sure as hell glad to know about that one :)
Feel free to include this in the merge commit, if you find it useful.
Thanks,
Vlastimil

- a few misc things
- kexec updates
- DMA-mapping updates to better support networking DMA operations
- IPC updates
- various MM changes to improve DAX fault handling
- lots of radix-tree changes, mainly to the test suite. All leading
up to reimplementing the IDA/IDR code to be a wrapper layer over the
radix-tree. However the final trigger-pulling patch is held off for
4.11.

- Please have a think about Oleg's "wait/ptrace: assume __WALL if the
child is traced". It's a kernel-based workaround for existing
userspace issues and is a form of non-back-compatible change.
- A few hotfixes
- befs cleanups
- nilfs2 updates
- sys_wait() changes
- kexec updates
- kdump
- scripts/gdb updates
- the last of the MM queue
- a few other misc things

[This is going to sound awfully self-glorifying. Oh well.] I did point
that out in another instance (memparse), which I think then got somewhat
fixed in a later version. Since Alexey and I seemed to disagree on what
guiding principles to use when doing the conversions and a number of
other points, I didn't have the energy to go through the entire series,
and the discussion died out.

No.
I'm not taking yet another broken "deprecate old interface, replace it
with new-and-improved one, and screw things up in the process".
The whole "kstrto*()" thing was a mistake. We had real bugs brought in
by the conversion to the "better" interface. The "even betterer" new
parse_integer() interface actually looks lik ea real improvement, and
talks about some of the brokenness of the old code, and I was really
wanting to like it, but then I saw the conversions.
The VERY FIRST conversion patch I looked at was buggy. That makes me
angry. The whole *AND*ONLY* point of this whole thing was to get rid
of bugs, and be a obviously safe interface, and then the first
conversion patch proves it wrong.
Let me show you:
if (isdigit(*str)) {
- io_tlb_nslabs = simple_strtoul(str, &str, 0);
+ str += parse_integer(str, 0, &io_tlb_nslabs);
and obviously nobody spent even a *second* asking themselves "what if
parse_integer returns an error".
The old code didn't fail catastrophically in the error case. The new one does.
And yes, parse_integer() really can return an error, even despite that
"isdigit(*str)" check. Think about it. Or just read the source code.
I really am very tired indeed of these "trivially obvious
improvements" that are buggy and actually introduce whole new ways to
write buggy code. Yes, the old code could miss an error. But the old
code wouldn't then create invalid pointers like the new code does.
I'm not thrilled about going through the rest of this sequence,
looking for other gotcha's. But I am *really* really tired of this
idiotic "let's make up a new interface that gets things right" and
then absolutely doesn't get it right at all. This is not just an issue
for number parseing - we had similar issues with the completely
moronic and misdesigned crap called "strlcpy()", which was introduced
for similar reasons, and also caused nasty bugs where the old code was
actually correct, and the "converted to better and safer interfaces"
code was actually buggy.
Mixing the error handling and the string update was a mistake.
Although *not* mixing it causes its own set of problems.
But whatever the final resolution to this is, I am *not* taking this
series. No way, no how. I liked the automatic type-based templating it
does, but I *don't* like the breakage that seems to be inevitable in
any large-scale conversion from a previously used historical
interface. People who implement new and improved interfaces always
seem to get that wrong.

In fact this is the harmless sort (changes only the error code of a
failure case) that might actually go in if there were any important
reason. But the smiley stands.

ABI changes are not a problem for -stable, so don't let that stop anyone

I would not recommend it for -stable.
It is an ABI change for the case of a security refusal.

Ah. The patch affects security code, but it doesn't actually address any
insecurity. I didn't think it was needed for -stable?
From: Roland McGrath <roland@redhat.com>
wait* syscalls return -ECHILD even when an individual PID of a live child
was requested explicitly, when security_task_wait denies the operation.
This means that something like a broken SELinux policy can produce an
unexpected failure that looks just like a bug with wait or ptrace or
something.
This patch makes do_wait return -EACCES (or other appropriate error returned
from security_task_wait() instead of -ECHILD if some children were ruled out
solely because security_task_wait failed.

Serial drivers? Well you saw me drop a bunch of them. I now have:
serial-driver-pmc-msp71xx.patch
rm9000-serial-driver.patch
serial-define-fixed_port-flag-for-serial_core.patch
mpsc-serial-driver-tx-locking.patch
serial-serial_core-use-pr_debug.patch
I'll also be holding off on MADV_FREE - Nick has some performance things to
share and I'm assuming they're not as good as he'd like.

I have some powerpc bits that depend on that stuff that will go through
Paulus after these show up in git and I've rebased.

So this is what I have lined up for the first mm->2.6.22 batch. I won't be
sending it off for another 12-24 hours yet. To give people time for final
comment and to give me time to see if it actually works.
- A few serial bits.
- A few pcmcia bits.
- Some of the MM queue. Includes:
- An enhancement to /proc/pid/smaps to permit monitoring of a running
program's working set.
There's another patchset which builds on this quite a lot from Matt
Mackall, but it's not quite ready yet.
- The SLUB allocator. It's pretty green but I do want to push ahead
with this pretty aggressively with a view to replacing slab altogether.
If it ends up not working out then we should remove slub altogether
again, but I doubt if that will occur.
If SLUB isn't in good shape by 2.6.22 we should hide it in Kconfig
to prevent people from hitting known problems. It'll remain
EXPERIMENTAL.
- generic pagetable quicklist management. We have x86_64 and ia64
and sparc64 implementations, but I'll only include David's sparc64
implementation here. I'll send the x86_64 and ia64 implementations
through maintainers.
- Various random MM bits

So this is what I have lined up for the first mm->2.6.22 batch. I won't be
sending it off for another 12-24 hours yet. To give people time for final
comment and to give me time to see if it actually works.
- A few serial bits.
- A few pcmcia bits.
- Some of the MM queue. Includes:
- An enhancement to /proc/pid/smaps to permit monitoring of a running
program's working set.
There's another patchset which builds on this quite a lot from Matt
Mackall, but it's not quite ready yet.
- The SLUB allocator. It's pretty green but I do want to push ahead
with this pretty aggressively with a view to replacing slab altogether.
If it ends up not working out then we should remove slub altogether
again, but I doubt if that will occur.
If SLUB isn't in good shape by 2.6.22 we should hide it in Kconfig
to prevent people from hitting known problems. It'll remain
EXPERIMENTAL.
- generic pagetable quicklist management. We have x86_64 and ia64
and sparc64 implementations, but I'll only include David's sparc64
implementation here. I'll send the x86_64 and ia64 implementations
through maintainers.
- Various random MM bits
- Benh's teach-get_unmapped_area-about-MAP_FIXED changes
- madvise(MADV_FREE)
This means I'm holding back Mel's page allocator work, and Andy's
lumpy-reclaim.
A shame in a way - I have high hopes for lumpy reclaim against the
moveable zone, but these things are not to be done lightly.

Looks fine with respect to my bits and Tejun's. Now Tejun's polling
identify is in I'll have a pile of patches next week as most PATA
controllers want to use this.

My sendpatchset tool should be good for this. It sends all but the
first message are sent in "Reference" to, and "In-Reply-To" the first
message.
http://www.speakeasy.org/~pj99/sgi/sendpatchset
I use it when sending out multiple patches in sequence from a quilt
repository.

The patch bombing seems to have really wedged vger. It took up to 24
hours to get all the messages.
Looks like Andrew's patch bomb script needs some rate limiting ;-)

I just double-checked, and I can say that I received all 198 emails from
vger...

I don't see a patch which adds linux/pm.h to linux/sysdev.h, which is
required to fix ARM builds in -rc2 and onwards kernels.
It is my understanding that you have such a patch, and if it isn't
going to be sent, I'd like to send my own fix so that ARM can start
building again in mainline.

Umm, what stops you from letting all the parts refer to part zero,

I'd like to second the idea of having all the patches be replies to this
original posting (ie one level of indenting for all patches). That way
a threaded view will only have one subject line for all 198 patches.

I meant something like this:
[patch 000/100] Foo-ize the baz.
[patch 001/100] Frob the baz
[patch 002/100] baz cleanups
[patch 003/100] apply foo-ization to baz
Rather than
[patch 000/100] Foo-ize the baz.
[patch 001/100] Frob the baz
[patch 002/100] baz cleanups
[patch 003/100] apply foo-ization to baz
Which would (as you rightly pointed out) be ludicrous.
i.e., all the patches are replys to the summary.

Is there any chance that in the future that these patch sets get posted
all to one thread? Perhaps as a reply to a summary? 1 thread to ignore
is preferable to 198.

As the commits list probably isn't working at present I'll cc linux-kernel
on this lot. Fairly cruel, sorry, but I don't like the idea of people not
knowing what's hitting the main tree.
This is the first live test of Linus's git-importing ability. I'm about
to disappear for 1.5 weeks - hope we'll still have a kernel left when I
get back.
- As we're still a fair way from 2.6.12 and things are still backing up,
it's a relatively large update.
- Various arch updates
- Big x86_64 update, as discussed
- decent-sized ppc32, ppc64 updates
- big infiniband update
- very nearly the last batch of u32->pm_message_t conversions. Some
other bits of this will be sitting out in subsystem trees - this is just
the stuff which doesn't overlap.
- the important fixes from the md, nfs4 queues
- other random fixes and things we probably want to have in 2.6.12.
- I'd draw especial Linus attention to:
"fix crash in entry.S restore_all" and
"pci enumeration on ixp2000: overflow in kernel/resource.c"
