[patch 1/5] mm/hugetlb.c: fix pages per hugetlb calculation

[Andrew Morton]

From: Mike Kravetz <mike.kravetz@oracle.com>
Subject: mm/hugetlb.c: fix pages per hugetlb calculation

The routine hpage_nr_pages() was incorrectly used to calculate the number
of base pages in a hugetlb page.  hpage_nr_pages is designed to be called
for THP pages and will return HPAGE_PMD_NR for hugetlb pages of any size.

Due to the context in which hpage_nr_pages was called, it is unlikely to
produce a user visible error.  The routine with the incorrect call is only
exercised in the case of hugetlb memory error or migration.  In addition,
this would need to be on an architecture which supports huge page sizes
less than PMD_SIZE.  And, the vma containing the huge page would also need
to smaller than PMD_SIZE.

[patch 2/5] samples/vfs: avoid warning in statx override

[Andrew Morton]

From: Kees Cook <keescook@chromium.org>
Subject: samples/vfs: avoid warning in statx override

Something changed recently to uncover this warning:

samples/vfs/test-statx.c:24:15: warning: `struct foo' declared inside parameter list will not be visible outside of this definition or declaration
   24 | #define statx foo
      |               ^~~

Which is due the use of "struct statx" (here, "struct foo") in a function
prototype argument list before it has been defined:

 int
 # 56 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h"
    foo
 # 56 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h" 3 4
          (int __dirfd, const char *__restrict __path, int __flags,
            unsigned int __mask, struct
 # 57 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h"
                                       foo
 # 57 "/usr/include/x86_64-linux-gnu/bits/statx-generic.h" 3 4
                                             *__restrict __buf)
   __attribute__ ((__nothrow__ , __leaf__)) __attribute__ ((__nonnull__ (2, 5)));

Add explicit struct before #include to avoid warning.

[patch 3/5] mm/cma.c: use exact_nid true to fix possible per-numa cma leak

[Andrew Morton]

From: Barry Song <song.bao.hua@hisilicon.com>
Subject: mm/cma.c: use exact_nid true to fix possible per-numa cma leak

Calling cma_declare_contiguous_nid() with false exact_nid for per-numa
reservation can easily cause cma leak and various confusion.  For example,
mm/hugetlb.c is trying to reserve per-numa cma for gigantic pages.  But it
can easily leak cma and make users confused when system has memoryless
nodes.

In case the system has 4 numa nodes, and only numa node0 has memory.  if
we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4
different numa nodes.  since exact_nid=false in current code, all 4 numa
nodes will get cma successfully from node0, but hugetlb_cma[1 to 3] will
never be available to hugepage will only allocate memory from
hugetlb_cma[0].

In case the system has 4 numa nodes, both numa node0&2 has memory, other
nodes have no memory.  if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c
will get 4 cma areas for 4 different numa nodes.  since exact_nid=false in
current code, all 4 numa nodes will get cma successfully from node0 or 2,
but hugetlb_cma[1] and [3] will never be available to hugepage as
mm/hugetlb.c will only allocate memory from hugetlb_cma[0] and
hugetlb_cma[2].  This causes permanent leak of the cma areas which are
supposed to be used by memoryless node.

Of cource we can workaround the issue by letting mm/hugetlb.c scan all cma
areas in alloc_gigantic_page() even node_mask includes node0 only.  that
means when node_mask includes node0 only, we can get page from
hugetlb_cma[1] to hugetlb_cma[3].  But this will cause kernel crash in
free_gigantic_page() while it wants to free page by:
cma_release(hugetlb_cma[page_to_nid(page)], page, 1 << order)

On the other hand, exact_nid=false won't consider numa distance, it might
be not that useful to leverage cma areas on remote nodes.  I feel it is
much simpler to make exact_nid true to make everything clear.  After that,
memoryless nodes won't be able to reserve per-numa CMA from other nodes
which have memory.

[patch 5/5] mm/page_alloc: fix documentation error

ee8eb9a5fe863 ("mm/page_alloc: increase default min_free_kbytes bound") I
forgot to tweak the above comment to reflect the new value.  This patch
fixes that mistake.

Subject: kasan: remove kasan_unpoison_stack_above_sp_to()

kasan_unpoison_stack_above_sp_to() is defined in kasan code but never
used.  The function was introduced as part of the commit:

   commit 9f7d416c36124667 ("kprobes: Unpoison stack in jprobe_return() for KASAN")

... where it was necessary because x86's jprobe_return() would leave
stale shadow on the stack, and was an oddity in that regard.

Since then, jprobes were removed entirely, and as of commit:

  commit 80006dbee674f9fa ("kprobes/x86: Remove jprobe implementation")

... there have been no callers of this function.

Remove the declaration and the implementation.

Subject: lib/test_kasan.c
: fix KASAN unit tests for tag-based KASAN

We use tag-based KASAN, then KASAN unit tests don't detect out-of-bounds
memory access. They need to be fixed.

With tag-based KASAN, the state of each 16 aligned bytes of memory is
encoded in one shadow byte and the shadow value is tag of pointer, so
we need to read next shadow byte, the shadow value is not equal to tag
value of pointer, so that tag-based KASAN will detect out-of-bounds
memory access.

From: Geert Uytterhoeven <geert@linux-m68k.org>
Subject: lib/test_bitops: do the full test during module init

Currently, the bitops test consists of two parts: one part is executed
during module load, the second part during module unload.  This is
cumbersome for the user, as he has to perform two steps to execute all
tests, and is different from most (all?) other tests.

Merge the two parts, so both are executed during module load.

has been removed from the -mm tree.  Its filename was
     mm-mremap-format-the-check-in-move_normal_pmd-same-as-move_huge_pmd.patch

This patch was dropped because it was nacked

------------------------------------------------------
From: Wei Yang <richard.weiyang@linux.alibaba.com>
Subject: mm/mremap: format the check in move_normal_pmd() same as move_huge_pmd()

Patch series "mm/mremap: cleanup move_page_tables() a little", v2.

move_page_tables() tries to move page table by PMD or PTE.

The root reason is if it tries to move PMD, both old and new range should
be PMD aligned.  But current code calculate old range and new range
separately.  This leads to some redundant check and calculation.

This cleanup tries to consolidate the range check in one place to reduce
some extra range handling.


This patch (of 4):

No functional change, just improve the readability and prepare for
following cleanup.

From: Wei Yang <richard.weiyang@linux.alibaba.com>
Subject: mm/mremap: it is sure to have enough space when extent meets requirement

old_end is passed to these two function to check whether there is enough
space to do the move, while this check is done before invoking these
functions.

These two functions only would be invoked when extent meets the
requirement and there is one check before invoking these functions:

    if (extent > old_end - old_addr)
        extent = old_end - old_addr;

This implies (old_end - old_addr) won't fail the check in these two
functions.

From: Wei Yang <richard.weiyang@linux.alibaba.com>
Subject: mm/mremap: calculate extent in one place

Page tables are moved on the base of PMD.  This requires both source and
destination range should meet the requirement.

Current code works well since move_huge_pmd() and move_normal_pmd() would
check old_addr and new_addr again.  And then return to move_ptes() if the
either of them is not aligned.

In stead of calculating the extent separately, it is better to calculate
in one place, so we know it is not necessary to try move pmd.  By doing
so, the logic seems a little clear.

destination.  This means when extent is HPAGE_PMD_SIZE or PMD_SIZE,
old_addr and new_addr are properly aligned too.

Since these two functions are only invoked in move_page_tables, it is safe
to remove the check now.

From: Muchun Song <songmuchun@bytedance.com>
Subject: mm/page_alloc.c: skip setting nodemask when we are in interrupt

When we are in the interrupt context, it is irrelevant to the current task
context.  If we use current task's mems_allowed, we can be fair to alloc
pages in the fast path and fall back to slow path memory allocation when
the current node(which is the current task mems_allowed) does not have
enough memory to allocate.  In this case, it slows down the memory
allocation speed of interrupt context.  So we can skip setting the
nodemask to allow any node to allocate memory, so that fast path
allocation can success.

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm/debug_vm_pgtable: add tests validating arch helpers for core MM features

Patch series "mm/debug_vm_pgtable: Add some more tests", v4.

This series adds some more arch page table helper validation tests which
are related to core and advanced memory functions.  This also creates a
documentation, enlisting expected semantics for all page table helpers as
suggested by Mike Rapoport previously
(https://lkml.org/lkml/2020/1/30/40).

There are many TRANSPARENT_HUGEPAGE and ARCH_HAS_TRANSPARENT_HUGEPAGE_PUD
ifdefs scattered across the test.  But consolidating all the fallback
stubs is not very straight forward because
ARCH_HAS_TRANSPARENT_HUGEPAGE_PUD is not explicitly dependent on
ARCH_HAS_TRANSPARENT_HUGEPAGE.

Tested on arm64, x86 platforms but only build tested on all other enabled
platforms through ARCH_HAS_DEBUG_VM_PGTABLE i.e powerpc, arc, s390.  The
following failure on arm64 still exists which was mentioned previously. 
It will be fixed with the upcoming THP migration on arm64 enablement
series.

WARNING .... mm/debug_vm_pgtable.c:860 debug_vm_pgtable+0x940/0xa54
WARN_ON(!pmd_present(pmd_mkinvalid(pmd_mkhuge(pmd))))


This patch (of 4):

This adds new tests validating arch page table helpers for these following
core memory features.  These tests create and test specific mapping types
at various page table levels.

1. SPECIAL mapping
2. PROTNONE mapping
3. DEVMAP mapping
4. SOFTDIRTY mapping
5. SWAP mapping
6. MIGRATION mapping
7. HUGETLB mapping
8. THP mapping

Subject: mm/debug_vm_pgtable: add tests validating advanced arch page table helpers

This adds new tests validating for these following arch advanced page
table helpers.  These tests create and test specific mapping types at
various page table levels.

1. pxxp_set_wrprotect()
2. pxxp_get_and_clear()
3. pxxp_set_access_flags()
4. pxxp_get_and_clear_full()
5. pxxp_test_and_clear_young()
6. pxx_leaf()
7. pxx_set_huge()
8. pxx_(clear|mk)_savedwrite()
9. huge_pxxp_xxx()

Subject: mm/debug_vm_pgtable: add debug prints for individual tests

This adds debug print information that enlists all tests getting executed
on a given platform.  With dynamic debug enabled, the following
information will be splashed during boot.  For compactness purpose,
dropped both time stamp and prefix (i.e debug_vm_pgtable) from this sample
output.

[debug_vm_pgtable      ]: Validating architecture page table helpers
[pte_basic_tests       ]: Validating PTE basic
[pmd_basic_tests       ]: Validating PMD basic
[p4d_basic_tests       ]: Validating P4D basic
[pgd_basic_tests       ]: Validating PGD basic
[pte_clear_tests       ]: Validating PTE clear
[pmd_clear_tests       ]: Validating PMD clear
[pte_advanced_tests    ]: Validating PTE advanced
[pmd_advanced_tests    ]: Validating PMD advanced
[hugetlb_advanced_tests]: Validating HugeTLB advanced
[pmd_leaf_tests        ]: Validating PMD leaf
[pmd_huge_tests        ]: Validating PMD huge
[pte_savedwrite_tests  ]: Validating PTE saved write
[pmd_savedwrite_tests  ]: Validating PMD saved write
[pmd_populate_tests    ]: Validating PMD populate
[pte_special_tests     ]: Validating PTE special
[pte_protnone_tests    ]: Validating PTE protnone

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: Documentation/mm: Add descriptions for arch page table helpers

This adds a specific description file for all arch page table helpers which
is in sync with the semantics being tested via CONFIG_DEBUG_VM_PGTABLE. All
future changes either to these descriptions here or the debug test should
always remain in sync.

+Architecture Page Table Helpers
+===============================
+
+Generic MM expects architectures (with MMU) to provide helpers to create, access
+and modify page table entries at various level for different memory functions.
+These page table helpers need to conform to a common semantics across platforms.
+Following tables describe the expected semantics which can also be tested during
+boot via CONFIG_DEBUG_VM_PGTABLE option. All future changes in here or the debug
+test need to be in sync.

[merged] slub-drop-lockdep_assert_held-from-put_map.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: mm/slub.c: drop lockdep_assert_held() from put_map()
has been removed from the -mm tree.  Its filename was
     slub-drop-lockdep_assert_held-from-put_map.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Subject: mm/slub.c: drop lockdep_assert_held() from put_map()

There is no point in using lockdep_assert_held() unlock that is about to
be unlocked.  It works only with lockdep and lockdep will complain if
spin_unlock() is used on a lock that has not been locked.

Remove superfluous lockdep_assert_held().

Subject: mm/slub.c: drop lockdep_assert_held() from put_map()

There is no point in using lockdep_assert_held() unlock that is about to
be unlocked.  It works only with lockdep and lockdep will complain if
spin_unlock() is used on a lock that has not been locked.

Remove superfluous lockdep_assert_held().

From: Zhen Lei <thunder.leizhen@huawei.com>
Subject: mm/mmap: optimize a branch judgment in ksys_mmap_pgoff()

Look at the pseudo code below.  It's very clear that, the judgement
"!is_file_hugepages(file)" at 3) is duplicated to the one at 1), we can
use "else if" to avoid it.  And the assignment "retval = -EINVAL" at 2) is
only needed by the branch 3), because "retval" will be overwritten at 4).

No functional change, but it can reduce the code size. Maybe more clearer?
Before:
text    data     bss     dec     hex filename
28733    1590       1   30324    7674 mm/mmap.o

After:
text    data     bss     dec     hex filename
28701    1590       1   30292    7654 mm/mmap.o

====pseudo code====:
	if (!(flags & MAP_ANONYMOUS)) {
		...
1)		if (is_file_hugepages(file))
			len = ALIGN(len, huge_page_size(hstate_file(file)));
2)		retval = -EINVAL;
3)		if (unlikely(flags & MAP_HUGETLB && !is_file_hugepages(file)))
			goto out_fput;
	} else if (flags & MAP_HUGETLB) {
		...
	}
	...

4)	retval = vm_mmap_pgoff(file, addr, len, prot, flags, pgoff);
out_fput:
	...
	return retval;

After commit fdc85222d58e ("kernfs: kvmalloc xattr value instead of

kmalloc(), so we should release it with kvfree() instead of kfree().

------------------------------------------------------
From: Long Li <lonuxli.64@gmail.com>
Subject: mm, slab: check GFP_SLAB_BUG_MASK before alloc_pages in kmalloc_order

kmalloc cannot allocate memory from HIGHMEM.  Allocating large amounts of
memory currently bypasses the check and will simply leak the memory when
page_address() returns NULL.  To fix this, factor the GFP_SLAB_BUG_MASK
check out of slab & slub, and call it from kmalloc_order() as well.  In
order to make the code clear, the warning message is put in one place.

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

Hi,
Not my call, but I would go with an incremental patch.

Will add ACPI as dependency in Kconfig for Renoir ACP driver.
Do i need to upload new version of the patch? or should i submit the 
incremental patch as a fix ?

Subject: mm/memory.c: avoid access flag update TLB flush for retried page fault

Recently we found regression when running will_it_scale/page_fault3 test
on ARM64.  Over 70% down for the multi processes cases and over 20% down
for the multi threads cases.  It turns out the regression is caused by
commit 89b15332af7c0 ("mm: drop mmap_sem before calling
balance_dirty_pages() in write fault").

The test mmaps a memory size file then write to the mapping, this would
make all memory dirty and trigger dirty pages throttle, that upstream
commit would release mmap_sem then retry the page fault.  The retried page
fault would see correct PTEs installed by the first try then update access
flags and flush TLBs.  The regression is caused by the excessive TLB
flush.  It is fine on x86 since x86 doesn't need flush TLB for access flag
update.

The page fault would be retried due to:
1. Waiting for page readahead
2. Waiting for page swapped in
3. Waiting for dirty pages throttling

The first two cases don't have PTEs set up at all, so the retried page
fault would install the PTEs, so they don't reach there.  But the #3 case
usually has PTEs installed, the retried page fault would reach the access
flag update.  But it seems not necessary to update access flags for #3
since retried page fault is not real "second access", so it sounds safe to
skip access flag update for retried page fault.

With this fix the test result get back to normal.

charge_slab_page() and uncharge_slab_page() are not related anymore to
memcg charging and uncharging.  In order to make their names less
confusing, let's rename them to account_slab_page() and
unaccount_slab_page() respectively.

Subject: mm: kmem: switch to static_branch_likely() in memcg_kmem_enabled()

Currently memcg_kmem_enabled() is optimized for the kernel memory
accounting being off.  It was so for a long time, and arguably the reason
behind was that the kernel memory accounting was initially an opt-in
feature.  However, now it's on by default on both cgroup v1 and cgroup v2,
and it's on for all cgroups.  So let's switch over to
static_branch_likely() to reflect this fact.

Unlikely there is a significant performance difference, as the cost of a
memory allocation and its accounting significantly exceeds the cost of a
jump.  However, the conversion makes the code look more logically.

Subject: fs/minix: check return value of sb_getblk()

Patch series "fs/minix: fix syzbot bugs and set s_maxbytes".

This series fixes all syzbot bugs in the minix filesystem:

	KASAN: null-ptr-deref Write in get_block
	KASAN: use-after-free Write in get_block
	KASAN: use-after-free Read in get_block
	WARNING in inc_nlink
	KMSAN: uninit-value in get_block
	WARNING in drop_nlink

It also fixes the minix filesystem to set s_maxbytes correctly, so that
userspace sees the correct behavior when exceeding the max file size.


This patch (of 6):

sb_getblk() can fail, so check its return value.

This fixes a NULL pointer dereference.

Originally from Qiujun Huang.

Subject: fs/minix: don't allow getting deleted inodes

If an inode has no links, we need to mark it bad rather than allowing it
to be accessed.  This avoids WARNINGs in inc_nlink() and drop_nlink() when
doing directory operations on a fuzzed filesystem.

Subject: fs/minix: reject too-large maximum file size

If the minix filesystem tries to map a very large logical block number to
its on-disk location, block_to_path() can return offsets that are too
large, causing out-of-bounds memory accesses when accessing indirect index
blocks.  This should be prevented by the check against the maximum file
size, but this doesn't work because the maximum file size is read directly
from the on-disk superblock and isn't validated itself.

Fix this by validating the maximum file size at mount time.

Subject: fs/minix: set s_maxbytes correctly

The minix filesystem leaves super_block::s_maxbytes at MAX_NON_LFS rather
than setting it to the actual filesystem-specific limit.  This is broken
because it means userspace doesn't see the standard behavior like getting
EFBIG and SIGXFSZ when exceeding the maximum file size.

Fix this by setting s_maxbytes correctly.

Subject: fs/minix: fix block limit check for V1 filesystems

The minix filesystem reads its maximum file size from its on-disk
superblock.  This value isn't necessarily a multiple of the block size. 
When it's not, the V1 block mapping code doesn't allow mapping the last
possible block.  Commit 6ed6a722f9ab ("minixfs: fix block limit check")
fixed this in the V2 mapping code.  Fix it in the V1 mapping code too.

From: Eric Biggers <ebiggers@google.com>
Subject: fs/minix: remove expected error message in block_to_path()

When truncating a file to a size within the last allowed logical block,
block_to_path() is called with the *next* block.  This exceeds the limit,
causing the "block %ld too big" error message to be printed.

This case isn't actually an error; there are just no more blocks past that
point.  So, remove this error message.

From: Barry Song <song.bao.hua@hisilicon.com>
Subject: mm/zswap: move to use crypto_acomp API for hardware acceleration

Right now, all new ZIP drivers are using crypto_acomp APIs rather than
legacy crypto_comp APIs.  But zswap.c is still using the old APIs.  That
means zswap won't be able to use any new zip drivers in kernel.

This patch moves to use cryto_acomp APIs to fix the problem.  On the other
hand, tradiontal compressors like lz4,lzo etc have been wrapped into acomp
via scomp backend.  So platforms without async compressors can fallback to
use acomp via scomp backend.

It is probably the first real user to use acomp but perhaps not a good
example to demonstrate how multiple acomp requests can be executed in
parallel in one acomp instance.  frontswap is doing page load and store
page by page.  It doesn't have a queuing or buffering mechinism to permit
multiple pages to do frontswap simultaneously in one thread.  However this
patch creates multiple acomp instances, so multiple threads running on
multiple different cpus can actually do (de)compression parallelly,
leveraging the power of multiple ZIP hardware queues.  This is also
consistent with frontswap's page management model.

On the other hand, the current zswap implementation has some per-cpu
global resource like zswap_dstmem.  So we create acomp instances in number
of CPUs just like before, zswap created comp instances in number of CPUs.

Subject: kthread: remove incorrect comment in kthread_create_on_cpu()

Originally kthread_create_on_cpu() parked and woke up the new thread. 
However, since commit a65d40961dc7 ("kthread/smpboot: do not park in
kthread_create_on_cpu()") this is no longer the case.  This patch removes
the comment that has been left behind and is now incorrect / stale.

From: Zhang Qiang <qiang.zhang@windriver.com>
Subject: kthread: work could not be queued when worker being destroyed

The "queuing_blocked" func should print warning message and returns true
when the worker being destroyed.

Before the work is put into the queue of the worker thread, the state of
the worker thread needs to be detected,because the worker thread may be in
the destruction state at this time.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/page_isolation: prefer the node of the source page

Patch series "clean-up the migration target allocation functions", v3.

This patchset clean-up the migration target allocation functions.

Contributions of this patchset are:
1. unify two hugetlb alloc functions. As a result, one is remained.
2. make one external hugetlb alloc function to internal one.
3. unify three functions for migration target allocation.


This patch (of 8):

For locality, it's better to migrate the page to the same node rather than
the node of the current caller's cpu.

[Andrew Morton]

The patch titled
     Subject: mm/hugetlb: unify migration callbacks
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-unify-migration-callbacks.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/hugetlb: unify migration callbacks

There is no difference between two migration callback functions,
alloc_huge_page_node() and alloc_huge_page_nodemask(), except
__GFP_THISNODE handling.

This patch adds an argument, gfp_mask, on alloc_huge_page_nodemask() and
replaces the callsite for alloc_huge_page_node() with the call to
alloc_huge_page_nodemask(..., __GFP_THISNODE).

It's safe to remove a node id check in alloc_huge_page_node() since
there is no caller passing NUMA_NO_NODE as a node id.

[Andrew Morton]

The patch titled
     Subject: mm/hugetlb: make hugetlb migration callback CMA aware
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-make-hugetlb-migration-callback-cma-aware.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/hugetlb: make hugetlb migration callback CMA aware

new_non_cma_page() in gup.c which try to allocate migration target page
requires to allocate the new page that is not on the CMA area. 
new_non_cma_page() implements it by removing __GFP_MOVABLE flag.  This way
works well for THP page or normal page but not for hugetlb page.

hugetlb page allocation process consists of two steps.  First is dequeing
from the pool.  Second is, if there is no available page on the queue,
allocating from the page allocator.

new_non_cma_page() can control allocation from the page allocator by
specifying correct gfp flag.  However, dequeing cannot be controlled until
now, so, new_non_cma_page() skips dequeing completely.  It is a suboptimal
since new_non_cma_page() cannot utilize hugetlb pages on the queue so this
patch tries to fix this situation.

This patch makes the deque function on hugetlb CMA aware and skip CMA
pages if newly added skip_cma argument is passed as true.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/migrate: make a standard migration target allocation function

There are some similar functions for migration target allocation.  Since
there is no fundamental difference, it's better to keep just one rather
than keeping all variants.  This patch implements base migration target
allocation function.  In the following patches, variants will be converted
to use this function.

Note that PageHighmem() call in previous function is changed to open-code
"is_highmem_idx()" since it provides more readability.

Subject: mm/gup: use a standard migration target allocation callback

There is a well-defined migration target allocation callback.  It's mostly
similar with new_non_cma_page() except considering CMA pages.

This patch adds a CMA consideration to the standard migration target
allocation callback and use it on gup.c.

Subject: mm/hugetlb: avoid hardcoding while checking if cma is enable

hugetlb_cma[0] can be NULL due to various reasons, for example, node0 has
no memory.  so NULL hugetlb_cma[0] doesn't necessarily mean cma is not
enabled.  gigantic pages might have been reserved on other nodes.

Fix 5.7-rc6-mm1 page migration crash in unmap_and_move(): when the
page to be migrated has been freed from under us, that is considered
a MIGRATEPAGE_SUCCESS, but no newpage has been allocated (and I don't
think it would ever need to be counted as a successful THP migration).

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm/vmstat: add events for THP migration without split

Add following new vmstat events which will help in validating THP
migration without split.  Statistics reported through these new VM events
will help in performance debugging.

1. THP_MIGRATION_SUCCESS
2. THP_MIGRATION_FAILURE
3. THP_MIGRATION_SPLIT

In addition, these new events also update normal page migration statistics
appropriately via PGMIGRATE_SUCCESS and PGMIGRATE_FAILURE.  While here,
this updates current trace event 'mm_migrate_pages' to accommodate now
available THP statistics.

+Quantifying Migration
+=====================
+Following events can be used to quantify page migration.
+
+1. PGMIGRATE_SUCCESS       /* Normal page migration success */
+2. PGMIGRATE_FAIL          /* Normal page migration failure */
+3. THP_MIGRATION_SUCCESS   /* Transparent huge page migration success */
+4. THP_MIGRATION_FAILURE   /* Transparent huge page migration failure */
+5. THP_MIGRATION_SPLIT     /* Transparent huge page got split, retried */
+
+THP_MIGRATION_SUCCESS is when THP is migrated successfully without getting
+split into it's subpages. THP_MIGRATION_FAILURE is when THP could neither
+be migrated nor be split. THP_MIGRATION_SPLIT is when THP could not
+just be migrated as is but instead get split into it's subpages and later
+retried as normal pages. THP events would also update normal page migration
+statistics PGMIGRATE_SUCCESS and PGMIGRATE_FAILURE. These events will help
+in quantifying and analyzing various THP migration events including both
+success and failure cases.

From: Hugh Dickins <hughd@google.com>
Subject: mm/memcg: fix refcount error while moving and swapping

It was hard to keep a test running, moving tasks between memcgs with
move_charge_at_immigrate, while swapping: mem_cgroup_id_get_many()'s
refcount is discovered to be 0 (supposedly impossible), so it is then
forced to REFCOUNT_SATURATED, and after thousands of warnings in quick
succession, the test is at last put out of misery by being OOM killed.

This is because of the way moved_swap accounting was saved up until the
task move gets completed in __mem_cgroup_clear_mc(), deferred from when
mem_cgroup_move_swap_account() actually exchanged old and new ids. 
Concurrent activity can free up swap quicker than the task is scanned,
bringing id refcount down 0 (which should only be possible when
offlining).

Just skip that optimization: do that part of the accounting immediately.

-Wtype-limits is included in -Wextra which is added at W=1.  It warns
(among other things) that 'comparison of an unsigned variable `< 0` is
always false.  This causes noisy warnings, especially when used in macros,
hence it is more suitable for W=2.

------------------------------------------------------
From: Barry Song <song.bao.hua@hisilicon.com>
Subject: mm/zswap: move to use crypto_acomp API for hardware acceleration

Right now, all new ZIP drivers are using crypto_acomp APIs rather than
legacy crypto_comp APIs.  But zswap.c is still using the old APIs.  That
means zswap won't be able to use any new zip drivers in kernel.

This patch moves to use cryto_acomp APIs to fix the problem.  On the other
hand, tradiontal compressors like lz4,lzo etc have been wrapped into acomp
via scomp backend.  So platforms without async compressors can fallback to
use acomp via scomp backend.

It is probably the first real user to use acomp but perhaps not a good
example to demonstrate how multiple acomp requests can be executed in
parallel in one acomp instance.  frontswap is doing page load and store
page by page.  It doesn't have a queuing or buffering mechinism to permit
multiple pages to do frontswap simultaneously in one thread.  However this
patch creates multiple acomp instances, so multiple threads running on
multiple different cpus can actually do (de)compression parallelly,
leveraging the power of multiple ZIP hardware queues.  This is also
consistent with frontswap's page management model.

On the other hand, the current zswap implementation has some per-cpu
global resource like zswap_dstmem.  So we create acomp instances in number
of CPUs just like before, zswap created comp instances in number of CPUs.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: powerpc: fix compilation warning caused by missing include of asm/pgalloc.h

Recent rework of asm/pgalloc.h caused a compilation warning reported by
kbuild bot:

All warnings (new ones prefixed by >>):

>> arch/powerpc/mm/nohash/tlb.c:409:6: warning: no previous prototype for
>> 'tlb_flush_pgtable' [-Wmissing-prototypes]
     409 | void tlb_flush_pgtable(struct mmu_gather *tlb, unsigned long address)
         |      ^~~~~~~~~~~~~~~~~

Add missing include of asm/pgtable.h to arch/powerpc/mm/nohash/tlb.c to
make tlb_flush_pgtable() prototype visible there.

Subject: mm/mremap: it is sure to have enough space when extent meets requirement

Patch series "mm/mremap: cleanup move_page_tables() a little".

move_page_tables() tries to move page table by PMD or PTE.

The root reason is if it tries to move PMD, both old and new range should
be PMD aligned.  But current code calculate old range and new range
separately.  This leads to some redundant check and calculation.

This cleanup tries to consolidate the range check in one place to reduce
some extra range handling.


This patch (of 4):

old_end is passed to these two functions to check whether there is enough
space to do the move, while this check is done before invoking these
functions.

These two functions only would be invoked when extent meets the
requirement and there is one check before invoking these functions:

    if (extent > old_end - old_addr)
        extent = old_end - old_addr;

This implies (old_end - old_addr) won't fail the check in these two
functions.

Subject: mm/mremap: calculate extent in one place

Page tables is moved on the base of PMD.  This requires both source and
destination range should meet the requirement.

Current code works well since move_huge_pmd() and move_normal_pmd() would
check old_addr and new_addr again.  And then return to move_ptes() if the
either of them is not aligned.

Instead of calculating the extent separately, it is better to calculate in
one place, so we know it is not necessary to try move pmd.  By doing so,
the logic seems a little clear.

Subject: mm/mremap: start addresses are properly aligned

After previous cleanup, extent is the minimal step for both source and
destination.  This means when extent is HPAGE_PMD_SIZE or PMD_SIZE,
old_addr and new_addr are properly aligned too.

Since these two functions are only invoked in move_page_tables, it is safe
to remove the check now.

Subject: mm/mremap: use pmd_addr_end to simplify the calculate of extent

The purpose of this code is to calculate the smaller extent in old and new
range.  Let's leverage pmd_addr_end() to do the calculation.

Hope this would make the code easier to read.

Subject: mm/swap_slots.c: simplify alloc_swap_slot_cache()

Patch series "clean up some functions in mm/swap_slots.c".

When I studied the code of mm/swap_slots.c, I found some places can be
improved.


This patch (of 3):

Both "slots" and "slots_ret" are only need to be freed when cache already
allocated.  Make them closer, seems more clear.

No functional change.

Subject: mm/swap_slots.c: simplify enable_swap_slots_cache()

Whether swap_slot_cache_initialized is true or false,
__reenable_swap_slots_cache() is always called.  To make this meaning
clear, leave only one call to __reenable_swap_slots_cache().  This also
make it clearer what extra needs be done when swap_slot_cache_initialized
is false.

No functional change.

From: Zhen Lei <thunder.leizhen@huawei.com>
Subject: mm/swap_slots.c: remove redundant check for swap_slot_cache_initialized

Because enable_swap_slots_cache can only become true in
enable_swap_slots_cache(), and depends on swap_slot_cache_initialized is
true before.  That means, when enable_swap_slots_cache is true,
swap_slot_cache_initialized is true also.

So the condition:
"swap_slot_cache_enabled && swap_slot_cache_initialized"
can be reduced to "swap_slot_cache_enabled"

And in mathematics:
"!swap_slot_cache_enabled || !swap_slot_cache_initialized"
is equal to "!(swap_slot_cache_enabled && swap_slot_cache_initialized)"

So no functional change.

From: Peter Xu <peterx@redhat.com>
Subject: mm: do page fault accounting in handle_mm_fault

Patch series "mm: Page fault accounting cleanups", v5.

This is v5 of the pf accounting cleanup series.  It originates from Gerald
Schaefer's report on an issue a week ago regarding to incorrect page fault
accountings for retried page fault after commit 4064b9827063 ("mm: allow
VM_FAULT_RETRY for multiple times"):

  https://lore.kernel.org/lkml/20200610174811.44b94525@thinkpad/

What this series did:

  - Correct page fault accounting: we do accounting for a page fault
    (no matter whether it's from #PF handling, or gup, or anything else)
    only with the one that completed the fault.  For example, page fault
    retries should not be counted in page fault counters.  Same to the
    perf events.

  - Unify definition of PERF_COUNT_SW_PAGE_FAULTS: currently this perf
    event is used in an adhoc way across different archs.

    Case (1): for many archs it's done at the entry of a page fault
    handler, so that it will also cover e.g.  errornous faults.

    Case (2): for some other archs, it is only accounted when the page
    fault is resolved successfully.

    Case (3): there're still quite some archs that have not enabled
    this perf event.

    Since this series will touch merely all the archs, we unify this
    perf event to always follow case (1), which is the one that makes most
    sense.  And since we moved the accounting into handle_mm_fault, the
    other two MAJ/MIN perf events are well taken care of naturally.

  - Unify definition of "major faults": the definition of "major
    fault" is slightly changed when used in accounting (not
    VM_FAULT_MAJOR).  More information in patch 1.

  - Always account the page fault onto the one that triggered the page
    fault.  This does not matter much for #PF handlings, but mostly for
    gup.  More information on this in patch 25.

Patchset layout:

Patch 1:     Introduced the accounting in handle_mm_fault(), not enabled.
Patch 2-23:  Enable the new accounting for arch #PF handlers one by one.
Patch 24:    Enable the new accounting for the rest outliers (gup, iommu, etc.)
Patch 25:    Cleanup GUP task_struct pointer since it's not needed any more


This patch (of 25):

This is a preparation patch to move page fault accountings into the
general code in handle_mm_fault().  This includes both the per task
flt_maj/flt_min counters, and the major/minor page fault perf events.  To
do this, the pt_regs pointer is passed into handle_mm_fault().

PERF_COUNT_SW_PAGE_FAULTS should still be kept in per-arch page fault
handlers.

So far, all the pt_regs pointer that passed into handle_mm_fault() is
NULL, which means this patch should have no intented functional change.

From: Peter Xu <peterx@redhat.com>
Subject: mm: do page fault accounting in handle_mm_fault

Patch series "mm: Page fault accounting cleanups", v5.

This is v5 of the pf accounting cleanup series.  It originates from Gerald
Schaefer's report on an issue a week ago regarding to incorrect page fault
accountings for retried page fault after commit 4064b9827063 ("mm: allow
VM_FAULT_RETRY for multiple times"):

  https://lore.kernel.org/lkml/20200610174811.44b94525@thinkpad/

What this series did:

  - Correct page fault accounting: we do accounting for a page fault
    (no matter whether it's from #PF handling, or gup, or anything else)
    only with the one that completed the fault.  For example, page fault
    retries should not be counted in page fault counters.  Same to the
    perf events.

  - Unify definition of PERF_COUNT_SW_PAGE_FAULTS: currently this perf
    event is used in an adhoc way across different archs.

    Case (1): for many archs it's done at the entry of a page fault
    handler, so that it will also cover e.g.  errornous faults.

    Case (2): for some other archs, it is only accounted when the page
    fault is resolved successfully.

    Case (3): there're still quite some archs that have not enabled
    this perf event.

    Since this series will touch merely all the archs, we unify this
    perf event to always follow case (1), which is the one that makes most
    sense.  And since we moved the accounting into handle_mm_fault, the
    other two MAJ/MIN perf events are well taken care of naturally.

  - Unify definition of "major faults": the definition of "major
    fault" is slightly changed when used in accounting (not
    VM_FAULT_MAJOR).  More information in patch 1.

  - Always account the page fault onto the one that triggered the page
    fault.  This does not matter much for #PF handlings, but mostly for
    gup.  More information on this in patch 25.

Patchset layout:

Patch 1:     Introduced the accounting in handle_mm_fault(), not enabled.
Patch 2-23:  Enable the new accounting for arch #PF handlers one by one.
Patch 24:    Enable the new accounting for the rest outliers (gup, iommu, etc.)
Patch 25:    Cleanup GUP task_struct pointer since it's not needed any more


This patch (of 25):

This is a preparation patch to move page fault accountings into the
general code in handle_mm_fault().  This includes both the per task
flt_maj/flt_min counters, and the major/minor page fault perf events.  To
do this, the pt_regs pointer is passed into handle_mm_fault().

PERF_COUNT_SW_PAGE_FAULTS should still be kept in per-arch page fault
handlers.

So far, all the pt_regs pointer that passed into handle_mm_fault() is
NULL, which means this patch should have no intented functional change.

From: Peter Xu <peterx@redhat.com>
Subject: mm/alpha: use general page fault accounting

Use the general page fault accounting by passing regs into
handle_mm_fault().

Add the missing PERF_COUNT_SW_PAGE_FAULTS perf events too.  Note, the

Subject: mm/arc: use general page fault accounting

Use the general page fault accounting by passing regs into
handle_mm_fault().  It naturally solve the issue of multiple page fault
accounting when page fault retry happened.

Fix PERF_COUNT_SW_PAGE_FAULTS perf event manually for page fault retries,
by moving it before taking mmap_sem.

Subject: mm/hexagon: use general page fault accounting

Use the general page fault accounting by passing regs into
handle_mm_fault().  It naturally solve the issue of multiple page fault
accounting when page fault retry happened.

Add the missing PERF_COUNT_SW_PAGE_FAULTS perf events too.  Note, the
other two perf events (PERF_COUNT_SW_PAGE_FAULTS_[MAJ|MIN]) were done in
handle_mm_fault().

Fix PERF_COUNT_SW_PAGE_FAULTS perf event manually for page fault retries,

handle_mm_fault().  It naturally solve the issue of multiple page fault
accounting when page fault retry happened.

Fix PERF_COUNT_SW_PAGE_FAULTS perf event manually for page fault retries,
by moving it before taking mmap_sem.

Subject: mm/xtensa: use general page fault accounting

Use the general page fault accounting by passing regs into
handle_mm_fault().  It naturally solve the issue of multiple page fault
accounting when page fault retry happened.

Remove the PERF_COUNT_SW_PAGE_FAULTS_[MAJ|MIN] perf events because it's
now also done in handle_mm_fault().

Move the PERF_COUNT_SW_PAGE_FAULTS event higher before taking mmap_sem for
the fault, then it'll match with the rest of the archs.

From: Peter Xu <peterx@redhat.com>
Subject: mm: clean up the last pieces of page fault accountings

Here're the last pieces of page fault accounting that were still done
outside handle_mm_fault() where we still have regs==NULL when calling
handle_mm_fault():

arch/powerpc/mm/copro_fault.c:   copro_handle_mm_fault
arch/sparc/mm/fault_32.c:        force_user_fault
arch/um/kernel/trap.c:           handle_page_fault
mm/gup.c:                        faultin_page
                                 fixup_user_fault
mm/hmm.c:                        hmm_vma_fault
mm/ksm.c:                        break_ksm

Some of them has the issue of duplicated accounting for page fault
retries.  Some of them didn't do the accounting at all.

This patch cleans all these up by letting handle_mm_fault() to do per-task
page fault accounting even if regs==NULL (though we'll still skip the perf
event accountings).  With that, we can safely remove all the outliers now.

There's another functional change in that now we account the page faults
to the caller of gup, rather than the task_struct that passed into the gup
code.  More information of this can be found at [1].

After this patch, below things should never be touched again outside
handle_mm_fault():

  - task_struct.[maj|min]_flt
  - PERF_COUNT_SW_PAGE_FAULTS_[MAJ|MIN]

[Andrew Morton]

The patch titled
     Subject: mm/gup: remove task_struct pointer for all gup code
has been added to the -mm tree.  Its filename is
     mm-gup-remove-task_struct-pointer-for-all-gup-code.patch

This patch should soon appear at
    http://ozlabs.org/~akpm/mmots/broken-out/mm-gup-remove-task_struct-pointer-for-all-gup-code.patch
and later at
    http://ozlabs.org/~akpm/mmotm/broken-out/mm-gup-remove-task_struct-pointer-for-all-gup-code.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: Peter Xu <peterx@redhat.com>
Subject: mm/gup: remove task_struct pointer for all gup code

After the cleanup of page fault accounting, gup does not need to pass
task_struct around any more.  Remove that parameter in the whole gup
stack.

mmotm 2020-07-08-19-28 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-07-08-19-28 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

mmotm 2020-07-08-19-28 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-07-08-19-28 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

From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
Subject: mm/debug: print head flags in dump_page

Tail page flags contain very little useful information.  Print the head
page's flags instead.  While the flags will contain "head" for tail pages,
this should not be too confusing as the previous line starts with the word
"head:" and so the flags should be interpreted as belonging to the head
page.

From: Roman Gushchin <guro@fb.com>
Subject: mm: memcontrol: avoid workload stalls when lowering memory.high

Memory.high limit is implemented in a way such that the kernel penalizes
all threads which are allocating a memory over the limit.  Forcing all
threads into the synchronous reclaim and adding some artificial delays
allows to slow down the memory consumption and potentially give some time
for userspace oom handlers/resource control agents to react.

It works nicely if the memory usage is hitting the limit from below,
however it works sub-optimal if a user adjusts memory.high to a value way
below the current memory usage.  It basically forces all workload threads
(doing any memory allocations) into the synchronous reclaim and sleep. 
This makes the workload completely unresponsive for a long period of time
and can also lead to a system-wide contention on lru locks.  It can happen
even if the workload is not actually tight on memory and has, for example,
a ton of cold pagecache.

In the current implementation writing to memory.high causes an atomic
update of page counter's high value followed by an attempt to reclaim
enough memory to fit into the new limit.  To fix the problem described
above, all we need is to change the order of execution: try to push the
memory usage under the limit first, and only then set the new high limit.

From: Ralph Campbell <rcampbell@nvidia.com>
Subject: mm/migrate: optimize migrate_vma_setup() for holes

Patch series "mm/migrate: optimize migrate_vma_setup() for holes".

A simple optimization for migrate_vma_*() when the source vma is not an
anonymous vma and a new test case to exercise it.


This patch (of 2):

When migrating system memory to device private memory, if the source
address range is a valid VMA range and there is no memory or a zero page,
the source PFN array is marked as valid but with no PFN.

This lets the device driver allocate private memory and clear it, then
insert the new device private struct page into the CPU's page tables when
migrate_vma_pages() is called.  migrate_vma_pages() only inserts the new
page if the VMA is an anonymous range.

There is no point in telling the device driver to allocate device private

entries as not migrating to avoid this overhead.

Subject: mm, oom: make the calculation of oom badness more accurate

Recently we found an issue on our production environment that when memcg
oom is triggered the oom killer doesn't chose the process with largest
resident memory but chose the first scanned process.  Note that all
processes in this memcg have the same oom_score_adj, so the oom killer
should chose the process with largest resident memory.

Bellow is part of the oom info, which is enough to analyze this issue.

[7516988.092344] oom_reaper: reaped process 5740 (pause), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

We can find that the first scanned process 5740 (pause) was killed, but
its rss is only one page.  That is because, when we calculate the oom
badness in oom_badness(), we always ignore the negtive point and convert
all of these negtive points to 1.  Now as oom_score_adj of all the
processes in this targeted memcg have the same value -998, the points of
these processes are all negtive value.  As a result, the first scanned
process will be killed.

The oom_socre_adj (-998) in this memcg is set by kubelet, because it is a
a Guaranteed pod, which has higher priority to prevent from being killed
by system oom.

To fix this issue, we should make the calculation of oom point more
accurate.  We can achieve it by convert the chosen_point from 'unsigned
long' to 'long'.

From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>
Subject: mm/mmap.c: close race between munmap() and expand_upwards()/downwards()

VMA with VM_GROWSDOWN or VM_GROWSUP flag set can change their size under
mmap_read_lock().  It can lead to race with __do_munmap():

	Thread A			Thread B
__do_munmap()
  detach_vmas_to_be_unmapped()
  mmap_write_downgrade()
				expand_downwards()
				  vma->vm_start = address;
				  // The VMA now overlaps with
				  // VMAs detached by the Thread A
				// page fault populates expanded part
				// of the VMA
  unmap_region()
    // Zaps pagetables partly
    // populated by Thread B

Similar race exists for expand_upwards().

The fix is to avoid downgrading mmap_lock in __do_munmap() if detached
VMAs are next to VM_GROWSDOWN or VM_GROWSUP VMA.

-Quantifying Migration
+Monitoring Migration
 =====================
-Following events can be used to quantify page migration.
 
-1. PGMIGRATE_SUCCESS       /* Normal page migration success */
-2. PGMIGRATE_FAIL          /* Normal page migration failure */
-3. THP_MIGRATION_SUCCESS   /* Transparent huge page migration success */
-4. THP_MIGRATION_FAILURE   /* Transparent huge page migration failure */
-5. THP_MIGRATION_SPLIT     /* Transparent huge page got split, retried */
-
-THP_MIGRATION_SUCCESS is when THP is migrated successfully without getting
-split into it's subpages. THP_MIGRATION_FAILURE is when THP could neither
-be migrated nor be split. THP_MIGRATION_SPLIT is when THP could not
-just be migrated as is but instead get split into it's subpages and later
-retried as normal pages. THP events would also update normal page migration
-statistics PGMIGRATE_SUCCESS and PGMIGRATE_FAILURE. These events will help
-in quantifying and analyzing various THP migration events including both
-success and failure cases.
+The following events (counters) can be used to monitor page migration.
+
+1. PGMIGRATE_SUCCESS: Normal page migration success. Each count means that a
+   page was migrated. If the page was a non-THP page, then this counter is
+   increased by one. If the page was a THP, then this counter is increased by
+   the number of THP subpages. For example, migration of a single 2MB THP that
+   has 4KB-size base pages (subpages) will cause this counter to increase by
+   512.
+
+2. PGMIGRATE_FAIL: Normal page migration failure. Same counting rules as for
+   _SUCCESS, above: this will be increased by the number of subpages, if it was
+   a THP.
+
+3. THP_MIGRATION_SUCCESS: A THP was migrated without being split.
+
+4. THP_MIGRATION_FAIL: A THP could not be migrated nor it could be split.
+
+5. THP_MIGRATION_SPLIT: A THP was migrated, but not as such: first, the THP had
+   to be split. After splitting, a migration retry was used for it's sub-pages.
+
+THP_MIGRATION_* events also update the appropriate PGMIGRATE_SUCCESS or
+PGMIGRATE_FAIL events. For example, a THP migration failure will cause both
+THP_MIGRATION_FAIL and PGMIGRATE_FAIL to increase.

From: Krzysztof Kozlowski <krzk@kernel.org>
Subject: iomap: constify ioreadX() iomem argument (as in generic implementation)

Patch series "iomap: Constify ioreadX() iomem argument", v3.

The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.

It seems there is nothing really stopping all of them to take pointer to
const.


This patch (of 4):

The ioreadX() and ioreadX_rep() helpers have inconsistent interface.  On
some architectures void *__iomem address argument is a pointer to const,
on some not.

Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

Subject: rtl818x: constify ioreadX() iomem argument (as in generic implementation)

The ioreadX() helpers have inconsistent interface.  On some architectures
void *__iomem address argument is a pointer to const, on some not.

Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

Subject: virtio: pci: constify ioreadX() iomem argument (as in generic implementation)

The ioreadX() helpers have inconsistent interface.  On some architectures
void *__iomem address argument is a pointer to const, on some not.

Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

------------------------------------------------------
From: Feng Tang <feng.tang@intel.com>
Subject: proc/meminfo: avoid open coded reading of vm_committed_as

Patch series "make vm_committed_as_batch aware of vm overcommit policy", v5.

When checking a performance change for will-it-scale scalability mmap test
[1], we found very high lock contention for spinlock of percpu counter
'vm_committed_as':

    94.14%     0.35%  [kernel.kallsyms]         [k] _raw_spin_lock_irqsave
    48.21% _raw_spin_lock_irqsave;percpu_counter_add_batch;__vm_enough_memory;mmap_region;do_mmap;
    45.91% _raw_spin_lock_irqsave;percpu_counter_add_batch;__do_munmap;

Actually this heavy lock contention is not always necessary.  The
'vm_committed_as' needs to be very precise when the strict
OVERCOMMIT_NEVER policy is set, which requires a rather small batch number
for the percpu counter.

So keep 'batch' number unchanged for strict OVERCOMMIT_NEVER policy, and
enlarge it for not-so-strict OVERCOMMIT_ALWAYS and OVERCOMMIT_GUESS
policies.

Benchmark with the same testcase in [1] shows 53% improvement on a 8C/16T
desktop, and 2097%(20X) on a 4S/72C/144T server.  And for that case,
whether it shows improvements depends on if the test mmap size is bigger
than the batch number computed.

We tested 10+ platforms in 0day (server, desktop and laptop).  If we lift
it to 64X, 80%+ platforms show improvements, and for 16X lift, 1/3 of the
platforms will show improvements.

And generally it should help the mmap/unmap usage,as Michal Hocko
mentioned:

: I believe that there are non-synthetic worklaods which would benefit
: from a larger batch. E.g. large in memory databases which do large
: mmaps during startups from multiple threads.

Note: There are some style complain from checkpatch for patch 3, as sysctl
handler declaration follows the similar format of sibling functions

[1] https://lore.kernel.org/lkml/20200305062138.GI5972@shao2-debian/

patch1: a cleanup for /proc/meminfo
patch2: a preparation patch which also improve the accuracy of
        vm_memory_committed
patch3: main change


This patch (of 3):

Use the existing vm_memory_committed() instead, which is also convenient
for future change.

From: Feng Tang <feng.tang@intel.com>
Subject: mm/util.c: make vm_memory_committed() more accurate

percpu_counter_sum_positive() will provide more accurate info.

As with percpu_counter_read_positive(), in worst case the deviation could
be 'batch * nr_cpus', which is totalram_pages/256 for now, and will be
more when the batch gets enlarged.

Its time cost is about 800 nanoseconds on a 2C/4T platform and 2~3
microseconds on a 2S/36C/72T Skylake server in normal case, and in worst
case where vm_committed_as's spinlock is under severe contention, it costs
30~40 microseconds for the 2S/36C/72T Skylake sever, which should be fine
for its only two users: /proc/meminfo and HyperV balloon driver's status
trace per second.

------------------------------------------------------
From: Feng Tang <feng.tang@intel.com>
Subject: mm: adjust vm_committed_as_batch according to vm overcommit policy

When checking a performance change for will-it-scale scalability mmap test
[1], we found very high lock contention for spinlock of percpu counter
'vm_committed_as':

    94.14%     0.35%  [kernel.kallsyms]         [k] _raw_spin_lock_irqsave
    48.21% _raw_spin_lock_irqsave;percpu_counter_add_batch;__vm_enough_memory;mmap_region;do_mmap;
    45.91% _raw_spin_lock_irqsave;percpu_counter_add_batch;__do_munmap;

Actually this heavy lock contention is not always necessary.  The
'vm_committed_as' needs to be very precise when the strict
OVERCOMMIT_NEVER policy is set, which requires a rather small batch number
for the percpu counter.

So keep 'batch' number unchanged for strict OVERCOMMIT_NEVER policy, and
lift it to 64X for OVERCOMMIT_ALWAYS and OVERCOMMIT_GUESS policies.  Also
add a sysctl handler to adjust it when the policy is reconfigured.

Benchmark with the same testcase in [1] shows 53% improvement on a 8C/16T
desktop, and 2097%(20X) on a 4S/72C/144T server.  We tested with test
platforms in 0day (server, desktop and laptop), and 80%+ platforms shows
improvements with that test.  And whether it shows improvements depends on
if the test mmap size is bigger than the batch number computed.

And if the lift is 16X, 1/3 of the platforms will show improvements,
though it should help the mmap/unmap usage generally, as Michal Hocko
mentioned:

: I believe that there are non-synthetic worklaods which would benefit from
: a larger batch.  E.g.  large in memory databases which do large mmaps
: during startups from multiple threads.

[Andrew Morton]

The mm-of-the-moment snapshot 2020-07-09-21-00 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

[to-be-updated] mm-hugetlb-avoid-hardcoding-while-checking-if-cma-is-enable.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: mm/hugetlb: avoid hardcoding while checking if cma is enabled
has been removed from the -mm tree.  Its filename was
     mm-hugetlb-avoid-hardcoding-while-checking-if-cma-is-enable.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
From: Barry Song <song.bao.hua@hisilicon.com>
Subject: mm/hugetlb: avoid hardcoding while checking if cma is enabled

hugetlb_cma[0] can be NULL due to various reasons, for example, node0 has
no memory.  so NULL hugetlb_cma[0] doesn't necessarily mean cma is not
enabled.  gigantic pages might have been reserved on other nodes.

Mike Kravetz said:

: Based on the code changes, I believe the following could happen:
: - Someone uses 'hugetlb_cma=' kernel command line parameter to reserve
:   CMA for gigantic pages.
: - The system topology is such that no memory is on node 0.  Therefore,
:   no CMA can be reserved for gigantic pages on node 0.  CMA is reserved
:   on other nodes.
: - The user also specifies a number of gigantic pages to pre-allocate on
:   the command line with hugepagesz=<gigantic_page_size> hugepages=<N>
: - The routine which allocates gigantic pages from the bootmem allocator
:   will not detect CMA has been reserved as there is no memory on node 0.
:   Therefore, pages will be pre-allocated from bootmem allocator as well
:   as reserved in CMA.
: 
: This double allocation (bootmem and CMA) is the worst case scenario.  Not
: sure if this is what Barry saw, and I suspect this would rarely happen.

From: Julius Hemanth Pitti <jpitti@cisco.com>
Subject: proc/sysctl: make protected_* world readable

protected_* files have 600 permissions which prevents non-superuser from
reading them.

Container like "AWS greengrass" refuse to launch unless
protected_hardlinks and protected_symlinks are set.  When containers like
these run with "userns-remap" or "--user" mapping container's root to
non-superuser on host, they fail to run due to denied read access to these
files.

As these protections are hardly a secret, and do not possess any security
risk, making them world readable.

Though above greengrass usecase needs read access to only
protected_hardlinks and protected_symlinks files, setting all other
protected_* files to 644 to keep consistency.

Subject: mm/vmalloc.c: add an error message if two areas overlap

Before triggering a BUG() it would be useful to understand how two areas
overlap between each other.  Print information about start/end addresses
of both VAs and their addresses.

For example if both are identical it could mean double free.

Subject: rapidio/rio_mport_cdev: Use array_size() helper in copy_{from,to}_user()

Use array_size() helper instead of the open-coded version in
copy_{from,to}_user().  These sorts of multiplication factors need to be
wrapped in array_size().

This issue was found with the help of Coccinelle and, audited and fixed
manually.

From: Shakeel Butt <shakeelb@google.com>
Subject: mm: vmscan: consistent update to pgrefill

The vmstat pgrefill is useful together with pgscan and pgsteal stats to
measure the reclaim efficiency.  However vmstat's pgrefill is not updated
consistently at system level.  It gets updated for both global and memcg
reclaim however pgscan and pgsteal are updated for only global reclaim. 
So, update pgrefill only for global reclaim.  If someone is interested in
the stats representing both system level as well as memcg level reclaim,
then consult the root memcg's memory.stat instead of /proc/vmstat.

From: Chris Down <chris@chrisdown.name>
Subject: tmpfs: per-superblock i_ino support

Patch series "tmpfs: inode: Reduce risk of inum overflow", v7.

In Facebook production we are seeing heavy i_ino wraparounds on tmpfs.  On
affected tiers, in excess of 10% of hosts show multiple files with
different content and the same inode number, with some servers even having
as many as 150 duplicated inode numbers with differing file content.

This causes actual, tangible problems in production.  For example, we have
complaints from those working on remote caches that their application is
reporting cache corruptions because it uses (device, inodenum) to
establish the identity of a particular cache object, but because it's not
unique any more, the application refuses to continue and reports cache
corruption.  Even worse, sometimes applications may not even detect the
corruption but may continue anyway, causing phantom and hard to debug
behaviour.

In general, userspace applications expect that (device, inodenum) should
be enough to be uniquely point to one inode, which seems fair enough.  One
might also need to check the generation, but in this case:

1. That's not currently exposed to userspace
   (ioctl(...FS_IOC_GETVERSION...) returns ENOTTY on tmpfs);
2. Even with generation, there shouldn't be two live inodes with the
   same inode number on one device.

In order to mitigate this, we take a two-pronged approach:

1. Moving inum generation from being global to per-sb for tmpfs. This
   itself allows some reduction in i_ino churn. This works on both 64-
   and 32- bit machines.
2. Adding inode{64,32} for tmpfs. This fix is supported on machines with
   64-bit ino_t only: we allow users to mount tmpfs with a new inode64
   option that uses the full width of ino_t, or CONFIG_TMPFS_INODE64.

You can see how this compares to previous related patches which didn't
implement this per-superblock:

- https://patchwork.kernel.org/patch/11254001/
- https://patchwork.kernel.org/patch/11023915/


This patch (of 2):

get_next_ino has a number of problems:

- It uses and returns a uint, which is susceptible to become overflowed
  if a lot of volatile inodes that use get_next_ino are created.
- It's global, with no specificity per-sb or even per-filesystem. This
  means it's not that difficult to cause inode number wraparounds on a
  single device, which can result in having multiple distinct inodes
  with the same inode number.

This patch adds a per-superblock counter that mitigates the second case. 
This design also allows us to later have a specific i_ino size per-device,
for example, allowing users to choose whether to use 32- or 64-bit inodes
for each tmpfs mount.  This is implemented in the next commit.

For internal shmem mounts which may be less tolerant to spinlock delays,
we implement a percpu batching scheme which only takes the stat_lock at
each batch boundary.

From: Chris Down <chris@chrisdown.name>
Subject: tmpfs: support 64-bit inums per-sb

The default is still set to inode32 for backwards compatibility, but
system administrators can opt in to the new 64-bit inode numbers by
either:

1. Passing inode64 on the command line when mounting, or
2. Configuring the kernel with CONFIG_TMPFS_INODE64=y

The inode64 and inode32 names are used based on existing precedent from
XFS.

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:

From: Chris Down <chris@chrisdown.name>
Subject: mm, memcg: reclaim more aggressively before high allocator throttling

Patch series "mm, memcg: reclaim harder before high throttling", v2.


This patch (of 2):

In Facebook production, we've seen cases where cgroups have been put into
allocator throttling even when they appear to have a lot of slack file
caches which should be trivially reclaimable.

Looking more closely, the problem is that we only try a single cgroup
reclaim walk for each return to usermode before calculating whether or not
we should throttle.  This single attempt doesn't produce enough pressure
to shrink for cgroups with a rapidly growing amount of file caches prior
to entering allocator throttling.

As an example, we see that threads in an affected cgroup are stuck in
allocator throttling:

    # for i in $(cat cgroup.threads); do
    >     grep over_high "/proc/$i/stack"
    > done
    [<0>] mem_cgroup_handle_over_high+0x10b/0x150
    [<0>] mem_cgroup_handle_over_high+0x10b/0x150
    [<0>] mem_cgroup_handle_over_high+0x10b/0x150

...however, there is no I/O pressure reported by PSI, despite a lot of
slack file pages:

    # cat memory.pressure
    some avg10=78.50 avg60=84.99 avg300=84.53 total=5702440903
    full avg10=78.50 avg60=84.99 avg300=84.53 total=5702116959
    # cat io.pressure
    some avg10=0.00 avg60=0.00 avg300=0.00 total=78051391
    full avg10=0.00 avg60=0.00 avg300=0.00 total=78049640
    # grep _file memory.stat
    inactive_file 1370939392
    active_file 661635072

This patch changes the behaviour to retry reclaim either until the current
task goes below the 10ms grace period, or we are making no reclaim
progress at all.  In the latter case, we enter reclaim throttling as
before.

To a user, there's no intuitive reason for the reclaim behaviour to differ
from hitting memory.high as part of a new allocation, as opposed to
hitting memory.high because someone lowered its value.  As such this also
brings an added benefit: it unifies the reclaim behaviour between the two.

There's precedent for this behaviour: we already do reclaim retries when
writing to memory.{high,max}, in max reclaim, and in the page allocator
itself.

From: Chris Down <chris@chrisdown.name>
Subject: mm, memcg: unify reclaim retry limits with page allocator

Reclaim retries have been set to 5 since the beginning of time in
commit 66e1707bc346 ("Memory controller: add per cgroup LRU and
reclaim").  However, we now have a generally agreed-upon standard for
page reclaim: MAX_RECLAIM_RETRIES (currently 16), added many years later
in commit 0a0337e0d1d1 ("mm, oom: rework oom detection").

In the absence of a compelling reason to declare an OOM earlier in memcg
context than page allocator context, it seems reasonable to supplant
MEM_CGROUP_RECLAIM_RETRIES with MAX_RECLAIM_RETRIES, making the page
allocator and memcg internals more similar in semantics when reclaim
fails to produce results, avoiding premature OOMs or throttling.

Subject: mm, memcg: avoid stale protection values when cgroup is above protection

Patch series "mm, memcg: memory.{low,min} reclaim fix & cleanup", v4.

This series contains a fix for a edge case in my earlier protection
calculation patches, and a patch to make the area overall a little more
robust to hopefully help avoid this in future.


This patch (of 2):

A cgroup can have both memory protection and a memory limit to isolate it
from its siblings in both directions - for example, to prevent it from
being shrunk below 2G under high pressure from outside, but also from
growing beyond 4G under low pressure.

Commit 9783aa9917f8 ("mm, memcg: proportional memory.{low,min} reclaim")
implemented proportional scan pressure so that multiple siblings in excess
of their protection settings don't get reclaimed equally but instead in
accordance to their unprotected portion.

During limit reclaim, this proportionality shouldn't apply of course:
there is no competition, all pressure is from within the cgroup and should
be applied as such.  Reclaim should operate at full efficiency.

However, mem_cgroup_protected() never expected anybody to look at the
effective protection values when it indicated that the cgroup is above its
protection.  As a result, a query during limit reclaim may return stale
protection values that were calculated by a previous reclaim cycle in
which the cgroup did have siblings.

When this happens, reclaim is unnecessarily hesitant and potentially slow
to meet the desired limit.  In theory this could lead to premature OOM
kills, although it's not obvious this has occurred in practice.

Workaround the problem by special casing reclaim roots in
mem_cgroup_protection.  These memcgs are never participating in the
reclaim protection because the reclaim is internal.

We have to ignore effective protection values for reclaim roots because
mem_cgroup_protected might be called from racing reclaim contexts with
different roots.  Calculation is relying on root -> leaf tree traversal
therefore top-down reclaim protection invariants should hold.  The only
exception is the reclaim root which should have effective protection set
to 0 but that would be problematic for the following setup:

 Let's have global and A's reclaim in parallel:
  |
  A (low=2G, usage = 3G, max = 3G, children_low_usage = 1.5G)
  |\
  | C (low = 1G, usage = 2.5G)
  B (low = 1G, usage = 0.5G)

 for A reclaim we have
 B.elow = B.low
 C.elow = C.low

 For the global reclaim
 A.elow = A.low
 B.elow = min(B.usage, B.low) because children_low_usage <= A.elow
 C.elow = min(C.usage, C.low)

 With the effective values resetting we have A reclaim
 A.elow = 0
 B.elow = B.low
 C.elow = C.low

 and global reclaim could see the above and then
 B.elow = C.elow = 0 because children_low_usage > A.elow

Which means that protected memcgs would get reclaimed.

In future we would like to make mem_cgroup_protected more robust against
racing reclaim contexts but that is likely more complex solution than this
simple workaround.

From: Chris Down <chris@chrisdown.name>
Subject: mm, memcg: decouple e{low,min} state mutations from protection checks

mem_cgroup_protected currently is both used to set effective low and min
and return a mem_cgroup_protection based on the result.  As a user, this
can be a little unexpected: it appears to be a simple predicate function,
if not for the big warning in the comment above about the order in which
it must be executed.

This change makes it so that we separate the state mutations from the
actual protection checks, which makes it more obvious where we need to be
careful mutating internal state, and where we are simply checking and
don't need to worry about that.

This patch (of 9):

For locality, it's better to migrate the page to the same node rather than
the node of the current caller's cpu.

Subject: mm/hugetlb: unify migration callbacks

There is no difference between two migration callback functions,
alloc_huge_page_node() and alloc_huge_page_nodemask(), except
__GFP_THISNODE handling.  It's redundant to have two almost similar
functions in order to handle this flag.  So, this patch tries to remove
one by introducing a new argument, gfp_mask, to
alloc_huge_page_nodemask().

After introducing gfp_mask argument, it's caller's job to provide correct
gfp_mask.  So, every callsites for alloc_huge_page_nodemask() are changed
to provide gfp_mask.

Note that it's safe to remove a node id check in alloc_huge_page_node()
since there is no caller passing NUMA_NO_NODE as a node id.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/migrate: clear __GFP_RECLAIM to make the migration callback consistent with regular THP allocations

new_page_nodemask is a migration callback and it tries to use a common gfp
flags for the target page allocation whether it is a base page or a THP. 
The later only adds GFP_TRANSHUGE to the given mask.  This results in the
allocation being slightly more aggressive than necessary because the
resulting gfp mask will contain also __GFP_RECLAIM_KSWAPD.  THP
allocations usually exclude this flag to reduce over eager background
reclaim during a high THP allocation load which has been seen during large
mmaps initialization.  There is no indication that this is a problem for
migration as well but theoretically the same might happen when migrating
large mappings to a different node.  Make the migration callback
consistent with regular THP allocations.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/migrate: introduce a standard migration target allocation function

There are some similar functions for migration target allocation.  Since
there is no fundamental difference, it's better to keep just one rather
than keeping all variants.  This patch implements base migration target
allocation function.  In the following patches, variants will be converted
to use this function.

Changes should be mechanical, but, unfortunately, there are some
differences.  First, some callers' nodemask is assgined to NULL since NULL
nodemask will be considered as all available nodes, that is,
&node_states[N_MEMORY].  Second, for hugetlb page allocation, gfp_mask is
redefined as regular hugetlb allocation gfp_mask plus __GFP_THISNODE if
user provided gfp_mask has it.  This is because future caller of this
function requires to set this node constaint.  Lastly, if provided nodeid
is NUMA_NO_NODE, nodeid is set up to the node where migration source
lives.  It helps to remove simple wrappers for setting up the nodeid.

Note that PageHighmem() call in previous function is changed to open-code
"is_highmem_idx()" since it provides more readability.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/memory_hotplug: remove a wrapper for alloc_migration_target()

To calculate the correct node to migrate the page for hotplug, we need to
check node id of the page.  Wrapper for alloc_migration_target() exists
for this purpose.

However, Vlastimil informs that all migration source pages come from a
single node.  In this case, we don't need to check the node id for each
page and we don't need to re-set the target nodemask for each page by
using the wrapper.  Set up the migration_target_control once and use it
for all pages.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm/sparse: cleanup the code surrounding memory_present()

After removal of CONFIG_HAVE_MEMBLOCK_NODE_MAP we have two equivalent
functions that call memory_present() for each region in memblock.memory:
sparse_memory_present_with_active_regions() and membocks_present().

Moreover, all architectures have a call to either of these functions
preceding the call to sparse_init() and in the most cases they are called
one after the other.

Mark the regions from memblock.memory as present during sparce_init() by
making sparse_init() call memblocks_present(), make memblocks_present()
and memory_present() functions static and remove redundant
sparse_memory_present_with_active_regions() function.

Also remove no longer required HAVE_MEMORY_PRESENT configuration option.

Subject: fat: fix fat_ra_init() for data clusters == 0

If data clusters == 0, fat_ra_init() calls the ->ent_blocknr() for the
cluster beyond ->max_clusters.

This checks the limit before initialization to suppress the warning.

From: "Uladzislau Rezki (Sony)" <urezki@gmail.com>
Subject: mm/vmalloc.c: remove BUG() from the find_va_links()

Get rid of BUG() macro, that should be used only when a critical situation
happens and a system is not able to function anymore.

Replace it with WARN() macro instead, dump some extra information about
start/end addresses of both VAs which overlap.  Such overlap data can help
to figure out what happened making further analysis easier.  For example
if both areas are identical it could mean a double free.

A recovery process consists of declining all further steps regarding
inserting of conflicting overlap range.  In that sense find_va_links() now
can return NULL, so its return value has to be checked by callers.

Side effect of such process is it can leak memory, but it is better than
just killing a machine for no good reason.  Apart of that a debugging
process can be done on alive system.

[Andrew Morton]

The mm-of-the-moment snapshot 2020-07-13-19-49 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

Subject: fs/ufs: avoid potential u32 multiplication overflow

The 64 bit ino is being compared to the product of two u32 values,
however, the multiplication is being performed using a 32 bit multiply so
there is a potential of an overflow.  To be fully safe, cast uspi->s_ncg
to a u64 to ensure a 64 bit multiplication occurs to avoid any chance of
overflow.

Add more accurate hypervisor check.  Someone kindly pointed me to
517c3ba00916 ("x86/speculation/mds: Apply more accurate check on
hypervisor platform"), and v2 had the same issue.

Subject: mm: memcg/slab: fix memory leak at non-root kmem_cache destroy

If the kmem_cache refcount is greater than one, we should not mark the
root kmem_cache as dying.  If we mark the root kmem_cache dying
incorrectly, the non-root kmem_cache can never be destroyed.  It resulted
in memory leak when memcg was destroyed.  We can use the following steps
to reproduce.

  1) Use kmem_cache_create() to create a new kmem_cache named A.
  2) Coincidentally, the kmem_cache A is an alias for kmem_cache B,
     so the refcount of B is just increased.
  3) Use kmem_cache_destroy() to destroy the kmem_cache A, just
     decrease the B's refcount but mark the B as dying.
  4) Create a new memory cgroup and alloc memory from the kmem_cache
     B. It leads to create a non-root kmem_cache for allocating memory.
  5) When destroy the memory cgroup created in the step 4), the
     non-root kmem_cache can never be destroyed.

If we repeat steps 4) and 5), this will cause a lot of memory leak.  So
only when refcount reach zero, we mark the root kmem_cache as dying.

From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>
Subject: mm,hwpoison: cleanup unused PageHuge() check

Patch series "Hwpoison soft-offline rework", v4.

This patchset was initially based on Naoya's hwpoison rework [1], so
thanks to him for the initial work.  I would also like to think Naoya for
testing the patchset off-line, and report any issues he found, that was
quite helpful.

This patchset aims to fix some issues laying in soft-offline handling, but
it also takes the chance and takes some further steps to perform cleanups
and some refactoring as well.


 - Motivation:

   A customer and I were facing an issue were processes were killed
   after having soft-offlined some of their pages.  This should not happen
   when soft-offlining, as it is meant to be non-disruptive.  I was able
   to reproduce the issue when I stressed the memory + soft offlining
   pages in the meantime.

   After debugging the issue, I saw that the problem was that pages
   were returned back to user-space after having offlined them properly. 
   So, when those pages were faulted in, the fault handler returned
   VM_FAULT_POISON all the way down to the arch handler, and it simply
   killed the process.

   After a further anaylsis, it became clear that the problem was that
   when kcompactd kicked in to migrate pages over, compaction_alloc
   callback was handing poisoned pages to the migrate routine.

   All this could happen because isolate_freepages_block and
   fast_isolate_freepages just check for the page to be PageBuddy, and
   since 1) poisoned pages can be part of a higher order page and 2)
   poisoned pages are also Page Buddy, they can sneak in easily.

   I also saw some other problems with sawap pages, but I suspected it
   to be the same sort of problem, so I did not follow that trace.

   The above refers to soft-offline.  But I also saw problems with
   hard-offline, specially hugetlb corruption, and some other weird stuff.
   (I could paste the logs)

   The full explanation refering to the soft-offline case can be found at [2].

 - Approach:

   The taken approach is to contain those pages and never let them hit
   neither pcplists nor buddy freelists.  Only when they are completely
   out of reach, we flag them as poisoned.

   A full explanation of this can be found in patch#11 and patch#12

 - Outcome:

   With this patchset, I no longer see the issues with soft-offline.

[2] https://lore.kernel.org/linux-mm/20190826104144.GA7849@linux/T/#u


This patch (of 15):

Drop the PageHuge check since memory_failure forks into memory_failure_hugetlb()
for hugetlb pages.

hpage is never used after try_to_split_thp_page() in memory_failure(), so
we don't have to update hpage.  So let's not recalculate/use hpage.

From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>
Subject: mm,hwpoison-inject: don't pin for hwpoison_filter

Another memory error injection interface debugfs:hwpoison/corrupt-pfn also
takes bogus refcount for hwpoison_filter().  It's justified because this
does a coarse filter, expecting that memory_failure() redoes the check for
sure.

Subject: mm,hwpoison: rework soft offline for free pages

When trying to soft-offline a free page, we need to first take it off the
buddy allocator.  Once we know is out of reach, we can safely flag it as
poisoned.

take_page_off_buddy will be used to take a page meant to be poisoned off
the buddy allocator.  take_page_off_buddy calls break_down_buddy_pages,
which splits a higher-order page in case our page belongs to one.

Once the page is under our control, we call page_handle_poison to set it
as poisoned and grab a refcount on it.

------------------------------------------------------
From: Oscar Salvador <osalvador@suse.de>
Subject: mm,hwpoison: rework soft offline for in-use pages

This patch changes the way we set and handle in-use poisoned pages.  Until
now, poisoned pages were released to the buddy allocator, trusting that
the checks that take place prior to deliver the page to its end user would
act as a safe net and would skip that page.

This has proved to be wrong, as we got some pfn walkers out there, like
compaction, that all they care is the page to be PageBuddy and be in a
freelist.

Although this might not be the only user, having poisoned pages in the
buddy allocator seems a bad idea as we should only have free pages that
are ready and meant to be used as such.

Before explaining the taken approach, let us break down the kind of pages
we can soft offline.

- Anonymous THP (after the split, they end up being 4K pages)
- Hugetlb
- Order-0 pages (that can be either migrated or invalited)

* Normal pages (order-0 and anon-THP)

  - If they are clean and unmapped page cache pages, we invalidate
    then by means of invalidate_inode_page().
  - If they are mapped/dirty, we do the isolate-and-migrate dance.

  Either way, do not call put_page directly from those paths.
  Instead, we keep the page and send it to page_set_poison to perform the
  right handling.

  Among other things, page_set_poison() sets the HWPoison flag and does the last
  put_page.
  This call to put_page is mainly to be able to call __page_cache_release,
  since this function is not exported.

  Down the chain, we placed a check for HWPoison page in
  free_pages_prepare, that just skips any poisoned page, so those pages
  do not end up either in a pcplist or in buddy-freelist.

  After that, we set the refcount on the page to 1 and we increment
  the poisoned pages counter.

  We could do as we do for free pages:
  1) wait until the page hits buddy's freelists
  2) take it off
  3) flag it

  The problem is that we could race with an allocation, so by the time we
  want to take the page off the buddy, the page is already allocated, so we
  cannot soft-offline it.
  This is not fatal of course, but if it is better if we can close the race
  as does not require a lot of code.

* Hugetlb pages

  - We isolate-and-migrate them

  There is no magic in here, we just isolate and migrate them.
  A new set of internal functions have been made to flag a hugetlb page as
  poisoned (SetPageHugePoisoned(), PageHugePoisoned(), ClearPageHugePoisoned())
  This allows us to flag the page when we migrate it, back in
  move_hugetlb_state().
  Later on we check whether the page is poisoned in __free_huge_page,
  and we bail out in that case before sending the page to e.g: active
  free list.
  This gives us full control of the page, and we can handle it
  page_handle_poison().

  In other words, we do not allow migrated hugepages to get back to the
  freelists.

  Since now the page has no user and has been migrated, we can call
  dissolve_free_huge_page, which will end up calling update_and_free_page.
  In update_and_free_page(), we check for the page to be poisoned.
  If it so, we handle it as we handle gigantic pages, i.e: we break down
  the page in order-0 pages and free them one by one.
  Doing so, allows us for free_pages_prepare to skip poisoned pages.

Because of the way we handle now in-use pages, we no longer need the
put-as-isolation-migratetype dance, that was guarding for poisoned pages
to end up in pcplists.

From: Oscar Salvador <osalvador@suse.de>
Subject: mm,hwpoison: refactor soft_offline_huge_page and __soft_offline_page

Merging soft_offline_huge_page and __soft_offline_page let us get rid of
quite some duplicated code, and makes the code much easier to follow.

Now, __soft_offline_page will handle both normal and hugetlb pages.

Note that move put_page() block to the beginning of page_handle_poison()
with drain_all_pages() in order to make sure that the target page is freed
and sent into free list to make take_page_off_buddy() work properly.

From: Oscar Salvador <osalvador@suse.de>
Subject: mm,hwpoison: return 0 if the page is already poisoned in soft-offline

Currently, there is an inconsistency when calling soft-offline from
different paths on a page that is already poisoned.

1) madvise:

        madvise_inject_error skips any poisoned page and continues
        the loop.
        If that was the only page to madvise, it returns 0.

2) /sys/devices/system/memory/:

        When calling soft_offline_page_store()->soft_offline_page(),
        we return -EBUSY in case the page is already poisoned.
        This is inconsistent with a) the above example and b)
        memory_failure, where we return 0 if the page was poisoned.

Fix this by dropping the PageHWPoison() check in madvise_inject_error, and
let soft_offline_page return 0 if it finds the page already poisoned.

Please, note that this represents a user-api change, since now the return
error when calling soft_offline_page_store()->soft_offline_page() will be
different.

Subject: mm,hwpoison: introduce MF_MSG_UNSPLIT_THP

memory_failure() is supposed to call action_result() when it handles
a memory error event, but there's one missing case. So let's add it.

I find that include/ras/ras_event.h has some other MF_MSG_* undefined,
so this patch also adds them.

"vmstat_refresh: nr_zone_write_pending -11" on our production hosts.  The
numbers of these warnings were relatively low and stable, so it didn't
look like we are systematically leaking the counters.  The corresponding
vmstat counters also looked sane.

These warnings are generated by the vmstat_refresh() function, which
assumes that atomic zone and numa counters can't go below zero.  However,
on a SMP machine it's not quite right: due to per-cpu caching it can in
theory be as low as -(zone threshold) * NR_CPUs.

For instance, let's say all cma pages are in use and NR_FREE_CMA_PAGES
reached 0.  Then we've reclaimed a small number of cma pages on each CPU
except CPU0, so that most percpu NR_FREE_CMA_PAGES counters are slightly
positive (the atomic counter is still 0).  Then somebody on CPU0 consumes
all these pages.  The number of pages can easily exceed the threshold and
a negative value will be committed to the atomic counter.

To fix the problem and avoid generating false warnings, let's just relax
the condition and warn only if the value is less than minus the maximum
theoretically possible drift value, which is 125 * number of online CPUs. 
It will still allow to catch systematic leaks, but will not generate bogus
warnings.

Subject: memcg, oom: check memcg margin for parallel oom

Memcg oom killer invocation is synchronized by the global oom_lock and
tasks are sleeping on the lock while somebody is selecting the victim or
potentially race with the oom_reaper is releasing the victim's memory. 
This can result in a pointless oom killer invocation because a waiter
might be racing with the oom_reaper

        P1              oom_reaper              P2
                        oom_reap_task           mutex_lock(oom_lock)
                                                out_of_memory # no victim because we have one already
                        __oom_reap_task_mm      mute_unlock(oom_lock)
 mutex_lock(oom_lock)
                        set MMF_OOM_SKIP
 select_bad_process
 # finds a new victim

The page allocator prevents from this race by trying to allocate after the
lock can be acquired (in __alloc_pages_may_oom) which acts as a last
minute check.  Moreover page allocator simply doesn't block on the
oom_lock and simply retries the whole reclaim process.

Memcg oom killer should do the last minute check as well.  Call
mem_cgroup_margin to do that.  Trylock on the oom_lock could be done as
well but this doesn't seem to be necessary at this stage.

[Andrew Morton]

The mm-of-the-moment snapshot 2020-07-16-22-52 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

From: Phillip Lougher <phillip@squashfs.org.uk>
Subject: squashfs: fix length field overlap check in metadata reading

This is a regression introduced by the "migrate from ll_rw_block usage to
BIO" patch.

Squashfs packs structures on byte boundaries, and due to that the length
field (of the metadata block) may not be fully in the current block.  The
new code rewrote and introduced a faulty check for that edge case.

From: Pekka Enberg <penberg@kernel.org>
Subject: mm: pgtable: make generic pgprot_* macros available for no-MMU

The <linux/pgtable.h> header defines some generic pgprot_*
implementations, but they are only available when CONFIG_MMU is enabled. 
The RISC-V architecture, for example, therefore defines some of these
pgprot_* macros for !NOMMU.

Let's make the pgprot_* generic available even for !NOMMU so we can remove
the RISC-V specific definitions.

Compile-tested with x86 defconfig, and riscv defconfig and !MMU defconfig.

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm/sparsemem: enable vmem_altmap support in vmemmap_populate_basepages()

Patch series "arm64: Enable vmemmap mapping from device memory", v4.

This series enables vmemmap backing memory allocation from device memory
ranges on arm64.  But before that, it enables vmemmap_populate_basepages()
and vmemmap_alloc_block_buf() to accommodate struct vmem_altmap based
alocation requests.


This patch (of 3):

vmemmap_populate_basepages() is used across platforms to allocate backing
memory for vmemmap mapping.  This is used as a standard default choice or
as a fallback when intended huge pages allocation fails.  This just
creates entire vmemmap mapping with base pages (PAGE_SIZE).

On arm64 platforms, vmemmap_populate_basepages() is called instead of the
platform specific vmemmap_populate() when ARM64_SWAPPER_USES_SECTION_MAPS
is not enabled as in case for ARM64_16K_PAGES and ARM64_64K_PAGES configs.

At present vmemmap_populate_basepages() does not support allocating from
driver defined struct vmem_altmap while trying to create vmemmap mapping
for a device memory range.  It prevents ARM64_16K_PAGES and
ARM64_64K_PAGES configs on arm64 from supporting device memory with
vmemap_altmap request.

This enables vmem_altmap support in vmemmap_populate_basepages() unlocking
device memory allocation for vmemap mapping on arm64 platforms with 16K or
64K base page configs.

Each architecture should evaluate and decide on subscribing device memory
based base page allocation through vmemmap_populate_basepages().  Hence
lets keep it disabled on all archs in order to preserve the existing
semantics.  A subsequent patch enables it on arm64.

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: mm/sparsemem: enable vmem_altmap support in vmemmap_alloc_block_buf()

There are many instances where vmemap allocation is often switched between
regular memory and device memory just based on whether altmap is available
or not.  vmemmap_alloc_block_buf() is used in various platforms to
allocate vmemmap mappings.  Lets also enable it to handle altmap based
device memory allocation along with existing regular memory allocations. 
This will help in avoiding the altmap based allocation switch in many
places.  To summarize there are two different methods to call
vmemmap_alloc_block_buf().

vmemmap_alloc_block_buf(size, node, NULL)   /* Allocate from system RAM */
vmemmap_alloc_block_buf(size, node, altmap) /* Allocate from altmap */

This converts altmap_alloc_block_buf() into a static function, drops it's
entry from the header and updates Documentation/vm/memory-model.rst.

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: arm64/mm: enable vmem_altmap support for vmemmap mappings

Device memory ranges when getting hot added into ZONE_DEVICE, might
require their vmemmap mapping's backing memory to be allocated from their
own range instead of consuming system memory.  This prevents large system
memory usage for potentially large device memory ranges.  Device driver
communicates this request via vmem_altmap structure.  Architecture needs
to take this request into account while creating and tearing down vemmmap
mappings.

This enables vmem_altmap support in vmemmap_populate() and vmemmap_free()
which includes vmemmap_populate_basepages() used for ARM64_16K_PAGES and
ARM64_64K_PAGES configs.

From: Gang He <ghe@suse.com>
Subject: ocfs2: fix remounting needed after setfacl command

When use setfacl command to change a file's acl, the user cannot get the
latest acl information from the file via getfacl command, until remounting
the file system.

e.g.
setfacl -m u:ivan:rw /ocfs2/ivan
getfacl /ocfs2/ivan
getfacl: Removing leading '/' from absolute path names
file: ocfs2/ivan
owner: root
group: root
user::rw-
group::r--
mask::r--
other::r--

The latest acl record("u:ivan:rw") cannot be returned via getfacl
command until remounting.

Naresh reported that linux-next build is broken on MIPS.  The problem is
reproducible using gcc 8 and 9, but not 10.

The problem was introduced by commit "mem: memcg/slab: use a single set of
kmem_caches for all allocations", which added an allocation of the space
for the obj_cgroup vector into the slab post hook and created a recursive
inlining.

The easies way to fix this is to move memcg_alloc_page_obj_cgroups() to
memcontrol.c and make it a generic (not static inline) function.  It
breaks the inlining recursion and fixes the build.

From: Pi-Hsun Shih <pihsun@chromium.org>
Subject: scripts/decode_stacktrace: strip basepath from all paths

Currently the basepath is removed only from the beginning of the string. 
When the symbol is inlined and there's multiple line outputs of addr2line,
only the first line would have basepath removed.

Change to remove the basepath prefix from all lines.

Subject: ntfs: fix ntfs_test_inode and ntfs_init_locked_inode function type

Clang's Control Flow Integrity (CFI) is a security mechanism that can help
prevent JOP chains, deployed extensively in downstream kernels used in
Android.

Its deployment is hindered by mismatches in function signatures.  For this
case, we make callbacks match their intended function signature, and cast
parameters within them rather than casting the callback when passed as a
parameter.

When running `mount -t ntfs ...` we observe the following trace:

mmotm 2020-07-20-19-06 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-07-20-19-06 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 5.8-rc6:

Thanks for the report!

I've applied a fix to ipsec-next just a minute ago.

From: "Michael J. Ruhl" <michael.j.ruhl@intel.com>
Subject: io-mapping: indicate mapping failure

The !ATOMIC_IOMAP version of io_maping_init_wc will always return success,
even when the ioremap fails.

Since the ATOMIC_IOMAP version returns NULL when the init fails, and
callers check for a NULL return on error this is unexpected.

During a device probe, where the ioremap failed, a crash can look
like this:

BUG: unable to handle page fault for address: 0000000000210000
 #PF: supervisor write access in kernel mode
 #PF: error_code(0x0002) - not-present page
 Oops: 0002 [#1] PREEMPT SMP
 CPU: 0 PID: 177 Comm:
 RIP: 0010:fill_page_dma [i915]

  i915_gem_init [i915]
  i915_driver_probe [i915]
  pci_device_probe
  really_probe
  driver_probe_device

The remap failure occurred much earlier in the probe.  If it had
been propagated, the driver would have exited with an error.

Return NULL on ioremap failure.

------------------------------------------------------
From: Peter Zijlstra <peterz@infradead.org>
Subject: mm: fix kthread_use_mm() vs TLB invalidate

For SMP systems using IPI based TLB invalidation, looking at
current->active_mm is entirely reasonable.  This then presents the
following race condition:

  CPU0			CPU1

  flush_tlb_mm(mm)	use_mm(mm)
    <send-IPI>
			  tsk->active_mm = mm;
			  <IPI>
			    if (tsk->active_mm == mm)
			      // flush TLBs
			  </IPI>
			  switch_mm(old_mm,mm,tsk);

Where it is possible the IPI flushed the TLBs for @old_mm, not @mm,
because the IPI lands before we actually switched.

Avoid this by disabling IRQs across changing ->active_mm and switch_mm().

[ There are all sorts of reasons this might be harmless for various
architecture specific reasons, but best not leave the door open at all.  ]

Subject: kernel: add a kernel_wait helper

Add a helper that waits for a pid and stores the status in the passed in
kernel pointer.  Use it to fix the usage of kernel_wait4 in
call_usermodehelper_exec_sync that only happens to work due to the
implicit set_fs(KERNEL_DS) for kernel threads.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/vmscan: make active/inactive ratio as 1:1 for anon lru

Patch series "workingset protection/detection on the anonymous LRU list", v7.


* PROBLEM
In current implementation, newly created or swap-in anonymous page is
started on the active list.  Growing the active list results in
rebalancing active/inactive list so old pages on the active list are
demoted to the inactive list.  Hence, hot page on the active list isn't
protected at all.

Following is an example of this situation.

Assume that 50 hot pages on active list and system can contain total 100
pages.  Numbers denote the number of pages on active/inactive list (active
| inactive).  (h) stands for hot pages and (uo) stands for used-once
pages.

1. 50 hot pages on active list
50(h) | 0

2. workload: 50 newly created (used-once) pages
50(uo) | 50(h)

3. workload: another 50 newly created (used-once) pages
50(uo) | 50(uo), swap-out 50(h)

As we can see, hot pages are swapped-out and it would cause swap-in later.

* SOLUTION
Since this is what we want to avoid, this patchset implements workingset
protection.  Like as the file LRU list, newly created or swap-in anonymous
page is started on the inactive list.  Also, like as the file LRU list, if
enough reference happens, the page will be promoted.  This simple
modification changes the above example as following.

1. 50 hot pages on active list
50(h) | 0

2. workload: 50 newly created (used-once) pages
50(h) | 50(uo)

3. workload: another 50 newly created (used-once) pages
50(h) | 50(uo), swap-out 50(uo)

hot pages remains in the active list. :)

* EXPERIMENT
I tested this scenario on my test bed and confirmed that this problem
happens on current implementation. I also checked that it is fixed by
this patchset.


* SUBJECT
workingset detection

* PROBLEM
Later part of the patchset implements the workingset detection for the
anonymous LRU list.  There is a corner case that workingset protection
could cause thrashing.  If we can avoid thrashing by workingset detection,
we can get the better performance.

Following is an example of thrashing due to the workingset protection.

1. 50 hot pages on active list
50(h) | 0

2. workload: 50 newly created (will be hot) pages
50(h) | 50(wh)

3. workload: another 50 newly created (used-once) pages
50(h) | 50(uo), swap-out 50(wh)

4. workload: 50 (will be hot) pages
50(h) | 50(wh), swap-in 50(wh)

5. workload: another 50 newly created (used-once) pages
50(h) | 50(uo), swap-out 50(wh)

6. repeat 4, 5

Without workingset detection, this kind of workload cannot be promoted and
thrashing happens forever.

* SOLUTION
Therefore, this patchset implements workingset detection.  All the
infrastructure for workingset detecion is already implemented, so there is
not much work to do.  First, extend workingset detection code to deal with
the anonymous LRU list.  Then, make swap cache handles the exceptional
value for the shadow entry.  Lastly, install/retrieve the shadow value
into/from the swap cache and check the refault distance.

* EXPERIMENT
I made a test program to imitates above scenario and confirmed that
problem exists.  Then, I checked that this patchset fixes it.

My test setup is a virtual machine with 8 cpus and 6100MB memory.  But,
the amount of the memory that the test program can use is about 280 MB. 
This is because the system uses large ram-backed swap and large ramdisk to
capture the trace.

Test scenario is like as below.

1. allocate cold memory (512MB)
2. allocate hot-1 memory (96MB)
3. activate hot-1 memory (96MB)
4. allocate another hot-2 memory (96MB)
5. access cold memory (128MB)
6. access hot-2 memory (96MB)
7. repeat 5, 6

Since hot-1 memory (96MB) is on the active list, the inactive list can
contains roughly 190MB pages.  hot-2 memory's re-access interval (96+128
MB) is more 190MB, so it cannot be promoted without workingset detection
and swap-in/out happens repeatedly.  With this patchset, workingset
detection works and promotion happens.  Therefore, swap-in/out occurs
less.

Here is the result. (average of 5 runs)

type swap-in swap-out
base 863240 989945
patch 681565 809273

As we can see, patched kernel do less swap-in/out.

* OVERALL TEST (ebizzy using modified random function)
ebizzy is the test program that main thread allocates lots of memory and
child threads access them randomly during the given times.  Swap-in will
happen if allocated memory is larger than the system memory.

The random function that represents the zipf distribution is used to make
hot/cold memory.  Hot/cold ratio is controlled by the parameter.  If the
parameter is high, hot memory is accessed much larger than cold one.  If
the parameter is low, the number of access on each memory would be
similar.  I uses various parameters in order to show the effect of
patchset on various hot/cold ratio workload.

My test setup is a virtual machine with 8 cpus, 1024 MB memory and 5120 MB
ram swap.

Result format is as following.

param: 1-1024-0.1
- 1 (number of thread)
- 1024 (allocated memory size, MB)
- 0.1 (zipf distribution alpha,
0.1 works like as roughly uniform random,
1.3 works like as small portion of memory is hot and the others are cold)

pswpin: smaller is better
std: standard deviation
improvement: negative is better

As we can see, all the cases show improvement.  Especially, test case with
zipf distribution 1.3 show more improvements.  It means that if there is a
hot/cold tendency in anon pages, this patchset works better.


This patch (of 6):

Current implementation of LRU management for anonymous page has some
problems.  Most important one is that it doesn't protect the workingset,
that is, pages on the active LRU list.  Although, this problem will be
fixed in the following patchset, the preparation is required and this
patch does it.

What following patch does is to implement workingset protection.  After
the following patchset, newly created or swap-in pages will start their
lifetime on the inactive list.  If inactive list is too small, there is
not enough chance to be referenced and the page cannot become the
workingset.

In order to provide the newly anonymous or swap-in pages enough chance to
be referenced again, this patch makes active/inactive LRU ratio as 1:1.

This is just a temporary measure.  Later patch in the series introduces
workingset detection for anonymous LRU that will be used to better decide
if pages should start on the active and inactive list.  Afterwards this
patch is effectively reverted.

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/vmscan: protect the workingset on anonymous LRU

In current implementation, newly created or swap-in anonymous page is
started on active list.  Growing active list results in rebalancing
active/inactive list so old pages on active list are demoted to inactive
list.  Hence, the page on active list isn't protected at all.

Following is an example of this situation.

Assume that 50 hot pages on active list.  Numbers denote the number of
pages on active/inactive list (active | inactive).

1. 50 hot pages on active list
50(h) | 0

2. workload: 50 newly created (used-once) pages
50(uo) | 50(h)

3. workload: another 50 newly created (used-once) pages
50(uo) | 50(uo), swap-out 50(h)

This patch tries to fix this issue.  Like as file LRU, newly created or
swap-in anonymous pages will be inserted to the inactive list.  They are
promoted to active list if enough reference happens.  This simple
modification changes the above example as following.

1. 50 hot pages on active list
50(h) | 0

2. workload: 50 newly created (used-once) pages
50(h) | 50(uo)

3. workload: another 50 newly created (used-once) pages
50(h) | 50(uo), swap-out 50(uo)

As you can see, hot pages on active list would be protected.

Note that, this implementation has a drawback that the page cannot be
promoted and will be swapped-out if re-access interval is greater than the
size of inactive list but less than the size of total(active+inactive). 
To solve this potential issue, following patch will apply workingset
detection similar to the one that's already applied to file LRU.

Subject: mm/workingset: prepare the workingset detection infrastructure for anon LRU

To prepare the workingset detection for anon LRU, this patch splits
workingset event counters for refault, activate and restore into anon and
file variants, as well as the refaults counter in struct lruvec.

Subject: mm/swap: implement workingset detection for anonymous LRU

This patch implements workingset detection for anonymous LRU.  All the
infrastructure is implemented by the previous patches so this patch just
activates the workingset detection by installing/retrieving the shadow
entry and adding refault calculation.

Subject: mm/vmscan: restore active/inactive ratio for anonymous LRU

Now that workingset detection is implemented for anonymous LRU, we don't
need large inactive list to allow detecting frequently accessed pages
before they are reclaimed, anymore.  This effectively reverts the
temporary measure put in by commit "mm/vmscan: make active/inactive ratio
as 1:1 for anon lru".

From: Feng Tang <feng.tang@intel.com>
Subject: ./Makefile: add debug option to enable function aligned on 32 bytes

Recently 0day reported many strange performance changes (regression or
improvement), in which there was no obvious relation between the culprit
commit and the benchmark at the first look, and it causes people to doubt
the test itself is wrong.

Upon further check, many of these cases are caused by the change to the
alignment of kernel text or data, as whole text/data of kernel are linked
together, change in one domain may affect alignments of other domains.

gcc has an option '-falign-functions=n' to force text aligned, and with
that option enabled, some of those performance changes will be gone, like
[1][2][3].

Add this option so that developers and 0day can easily find performance
bump caused by text alignment change, as tracking these strange bump is
quite time consuming.  Though it can't help in other cases like data
alignment changes like [4].

Following is some size data for v5.7 kernel built with a RHEL config used
in 0day:

    text      data      bss	 dec	   filename
  19738771  13292906  5554236  38585913	 vmlinux.noalign
  19758591  13297002  5529660  38585253	 vmlinux.align32

Raw vmlinux size in bytes:

	v5.7		v5.7+align32
	253950832	254018000	+0.02%

Some benchmark data, most of them have no big change:

  * hackbench:		[ -1.8%,  +0.5%]

  * fsmark:		[ -3.2%,  +3.4%]  # ext4/xfs/btrfs

  * kbuild:		[ -2.0%,  +0.9%]

  * will-it-scale:	[ -0.5%,  +1.8%]  # mmap1/pagefault3

  * netperf:
    - TCP_CRR		[+16.6%, +97.4%]
    - TCP_RR		[-18.5%,  -1.8%]
    - TCP_STREAM	[ -1.1%,  +1.9%]

From: js1304@gmail.com
Subject: mm/page_alloc: fix memalloc_nocma_{save/restore} APIs


Currently, memalloc_nocma_{save/restore} API that prevents CMA area
in page allocation is implemented by using current_gfp_context(). However,
there are two problems of this implementation.

First, this doesn't work for allocation fastpath. In the fastpath,
original gfp_mask is used since current_gfp_context() is introduced in
order to control reclaim and it is on slowpath. So, CMA area can be
allocated through the allocation fastpath even if
memalloc_nocma_{save/restore} APIs are used. Currently, there is just
one user for these APIs and it has a fallback method to prevent actual
problem.
Second, clearing __GFP_MOVABLE in current_gfp_context() has a side effect
to exclude the memory on the ZONE_MOVABLE for allocation target.

To fix these problems, this patch changes the implementation to exclude
CMA area in page allocation. Main point of this change is using the
alloc_flags. alloc_flags is mainly used to control allocation so it fits
for excluding CMA area in allocation.

Since test_lockup is a test module to generate lockups, it is better to
limit TEST_LOCKUP to module (=m) or disabled (=n) because we can not use
the module parameters when CONFIG_TEST_LOCKUP=y.

Since filp_open() returns an error pointer, we should use IS_ERR() to
check the return value and then return PTR_ERR() if failed to get the
actual return value instead of always -EINVAL.

E.g. without this patch:

With this patch:

ls: cannot access no_such_file: No such file or directory
[root@localhost loongson]# modprobe test_lockup file_path=no_such_file lock_sb_umount time_secs=60 state=S

Numerous reports of kernel crashes due to this.  We can't figure out what
it's for or why it's in -next.

From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>
Subject: khugepaged: fix null-pointer dereference due to race

khugepaged has to drop mmap lock several times while collapsing a page. 
The situation can change while the lock is dropped and we need to
re-validate that the VMA is still in place and the PMD is still subject
for collapse.

But we miss one corner case: while collapsing an anonymous pages the VMA
could be replaced with file VMA. If the file VMA doesn't have any
private pages we get NULL pointer dereference:

	general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN
	KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]
	anon_vma_lock_write include/linux/rmap.h:120 [inline]
	collapse_huge_page mm/khugepaged.c:1110 [inline]
	khugepaged_scan_pmd mm/khugepaged.c:1349 [inline]
	khugepaged_scan_mm_slot mm/khugepaged.c:2110 [inline]
	khugepaged_do_scan mm/khugepaged.c:2193 [inline]
	khugepaged+0x3bba/0x5a10 mm/khugepaged.c:2238

The fix is to make sure that the VMA is anonymous in
hugepage_vma_revalidate().  The helper is only used for collapsing
anonymous pages.

From: Miaohe Lin <linmiaohe@huawei.com>
Subject: mm: mmap: merge vma after call_mmap() if possible

The vm_flags may be changed after call_mmap() because drivers may set some
flags for their own purpose.  As a result, we failed to merge the adjacent
vma due to the different vm_flags as userspace can't pass in the same one.
Try to merge vma after call_mmap() to fix this issue.

- 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):

  Subject: [patch 1/5] fs/binfmt_elf: fix PT_LOAD p_align values ..

  Subject: [patch 5/5] kfence: make test case compatible with run..

and not the other one with GUP patches?

For my own piece of mind, I've checked that this part (patches 1 to 33)
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: 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.

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.

- Everything else

The patch didn't update KASAN_STACK dependency in kconfig:
        config GCC_PLUGIN_STRUCTLEAK_BYREF
....
               depends on !(KASAN && KASAN_STACK=1)

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’:
  lib/crypto/curve25519-hacl64.c:601:1: warning: the frame size of

  lib/bitfield_kunit.c:93:1: warning: the frame size of 11200 bytes is
larger than 2048 bytes [-Wframe-larger-than=]

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

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

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.

Yes, I already have a request from Kees for linux-mm addition, so that

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..."

been caught that way?

If you use proper tools, add a "-M" to your diff script, so that you see

   941 files changed, 2614 insertions(+), 3696 deletions(-)

because a big portion of the lines were due to a rename:

   rename include/{asm-generic => linux}/pgtable.h (91%)

but at some earlier point you mentioned "diffstat", so I guess "proper
tools" isn't an option ;(

Hmm. I have no issues with conflicts, and already took your previous series.

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.

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
overall diffstat you have that

  include/linux/mm.h             |   19 +++++++++++++++----

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?

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

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?

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...

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?

I was hoping that we could at least test the THP locality thing? Is it
in your queue at all, or am I supposed to just do it myself?

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.

I'll take it as a trial. I added one-line notes about coda and the
PTRACE_GET_SYSCALL_INFO interface too.

I'll take it as a trial. I added one-line notes about coda and the

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

- the rest of MM

- various misc things

- procfs updates

- lib/ updates

- checkpatch updates

- kdump/kexec updates

- add kvmalloc helpers, use them

- time helper updates for Y2038 issues.  We're almost ready to remove
  current_fs_time() but that awaits a btrfs merge.

- add tracepoints to DAX.

- 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

[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

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.

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.

Cheers,
Ben.

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.

  A few MM things have been held back awaiting subsystem tree merges
  (probably x86 - I didn't check).


- One little security patch

- the blackfin architecture

- small h8300 update

- small alpha update

- swsusp updates

- m68k bits

- cris udpates

- Lots of UML updates

- v850, xtensa

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

sendpatchset has that, already builtin ;)

Though the 5 second delay might not be enough for someone
publishing at the rate Andrew does.

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...

Is it me, or were really only 117 mails of the 198 sent to lkml?

Great, thanks.  I must have missed it, sorry.

That fix is buried in [patch 105/198]

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,
instead of part n-1?

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.

I never got around to setting that up, plus the Subject:s pretty quickly
become invisible when they're indented 198 columns in GUI MUAs.

Hopefully we'll have the commits list running next time...

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"

A bunch of tricky stuff which I picked up off the internets.  They've been
