[patch 1/7] mm, memcg: fix inconsistent oom event behavior

[Andrew Morton]

From: Yafang Shao <laoar.shao@gmail.com>
Subject: mm, memcg: fix inconsistent oom event behavior

A recent commit 9852ae3fe529 ("mm, memcg: consider subtrees in
memory.events") changes the behavior of memcg events, which will consider
subtrees in memory.events.  But oom_kill event is a special one as it is
used in both cgroup1 and cgroup2.  In cgroup1, it is displayed in
memory.oom_control.  The file memory.oom_control is in both root memcg and
non root memcg, that is different with memory.event as it only in non-root
memcg.  That commit is okay for cgroup2, but it is not okay for cgroup1 as
it will cause inconsistent behavior between root memcg and non-root memcg.

Here's an example on why this behavior is inconsistent in cgroup1.
     root memcg
     /
  memcg foo
   /
memcg bar

Suppose there's an oom_kill in memcg bar, then the oon_kill will be

     root memcg : memory.oom_control(oom_kill)  0
     /
  memcg foo : memory.oom_control(oom_kill)  1
   /
memcg bar : memory.oom_control(oom_kill)  1

For the non-root memcg, its memory.oom_control(oom_kill) includes its
descendants' oom_kill, but for root memcg, it doesn't include its
descendants' oom_kill.  That means, memory.oom_control(oom_kill) has
different meanings in different memcgs.  That is inconsistent.  Then the
user has to know whether the memcg is root or not.

If we can't fully support it in cgroup1, for example by adding
memory.events.local into cgroup1 as well, then let's don't touch its
original behavior.

[patch 2/7] epoll: call final ep_events_available() check under the lock

[Andrew Morton]

From: Roman Penyaev <rpenyaev@suse.de>
Subject: epoll: call final ep_events_available() check under the lock

There is a possible race when ep_scan_ready_list() leaves ->rdllist and
->obflist empty for a short period of time although some events are
pending.  It is quite likely that ep_events_available() observes empty
lists and goes to sleep.  Since 339ddb53d373 ("fs/epoll: remove
unnecessary wakeups of nested epoll") we are conservative in wakeups
(there is only one place for wakeup and this is ep_poll_callback()), thus
ep_events_available() must always observe correct state of two lists.  The
easiest and correct way is to do the final check under the lock.  This
does not impact the performance, since lock is taken anyway for adding a
wait entry to the wait queue.

The discussion of the problem can be found here:
   https://lore.kernel.org/linux-fsdevel/a2f22c3c-c25a-4bda-8339-a7bdaf17849e@akamai.com/

In this patch barrierless __set_current_state() is used.  This is safe
since waitqueue_active() is called under the same lock on wakeup side.

Short-circuit for fatal signals (i.e.  fatal_signal_pending() check) is
moved to the line just before actual events harvesting routine.  This is
fully compliant to what is said in the comment of the patch where the
actual fatal_signal_pending() check was added: c257a340ede0 ("fs, epoll:
short circuit fetching events if thread has been killed").

[patch 3/7] mm/gup: fix fixup_user_fault() on multiple retries

[Andrew Morton]

From: Peter Xu <peterx@redhat.com>
Subject: mm/gup: fix fixup_user_fault() on multiple retries

This part is overlooked when reworking the gup code on multiple retries. 
When we get the 2nd+ retry, we'll be with TRIED flag set.  Current code
will bail out on the 2nd retry because the !TRIED check will fail so the
retry logic will be skipped.  What's worse is that, it will also return
zero which errornously hints the caller that the page is faulted in while
it's not.

The !TRIED flag check seems to not be needed even before the mutliple
retries change because if we get a VM_FAULT_RETRY, it must be the 1st
retry, and we should not have TRIED set for that.

Fix it by removing the !TRIED check, at the meantime check against fatal
signals properly before the page fault so we can still properly respond to
the user killing the process during retries.

[patch 4/7] userfaultfd: fix remap event with MREMAP_DONTUNMAP

[Andrew Morton]

From: Brian Geffon <bgeffon@google.com>
Subject: userfaultfd: fix remap event with MREMAP_DONTUNMAP

A user is not required to set a new address when using MREMAP_DONTUNMAP as
it can be used without MREMAP_FIXED.  When doing so the remap event will
use new_addr which may not have been set and we didn't propagate it back
other then in the return value of remap_to.

Because ret is always the new address it's probably more correct to use it
rather than new_addr on the remap_event_complete call, and it resolves
this bug.

[patch 6/7] kasan: consistently disable debugging features

[Andrew Morton]

From: Andrey Konovalov <andreyknvl@google.com>
Subject: kasan: consistently disable debugging features

KASAN is incompatible with some kernel debugging/tracing features. 
There's been multiple patches that disable those feature for some of KASAN
files one by one.  Instead of prolonging that, disable these features for
all KASAN files at once.

[failures] vfs-keep-inodes-with-page-cache-off-the-inode-shrinker-lru.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: Re: vfs: keep inodes with page cache off the inode shrinker LRU
has been removed from the -mm tree.  Its filename was
     vfs-keep-inodes-with-page-cache-off-the-inode-shrinker-lru.patch

This patch was dropped because it had testing failures

------------------------------------------------------
From: Johannes Weiner <hannes@cmpxchg.org>
Subject: Re: vfs: keep inodes with page cache off the inode shrinker LRU

The VFS inode shrinker is currently allowed to reclaim cold inodes with
populated page cache.  This behavior goes back to CONFIG_HIGHMEM setups,
which required the ability to drop page cache in large highem zones to
free up struct inodes in comparatively tiny lowmem zones.

However, it has significant side effects that are hard to justify on
systems without highmem:

- It can drop gigabytes of hot and active page cache on the floor
  without consulting the VM (recorded as "inodesteal" events in
  /proc/vmstat).  Such an "aging inversion" between unreferenced inodes
  holding hot cache easily happens in practice: for example, a git tree
  whose objects are accessed frequently but no open file descriptors are
  maintained throughout.

- It can als prematurely drop non-resident info stored inside the
  inodes, which can let massive cache thrashing go unnoticed.  This in
  turn means we're making the wrong decisions in page reclaim and can get
  stuck in pathological thrashing.  The thrashing also doesn't show up as
  memory pressure in psi, causing failure in the userspace OOM detection
  chain, which can leave a system (or Android device e.g.) stranded in a
  livelock.

History

As this keeps causing problems for people, there have been several
attempts to address this.

One recent attempt was to make the inode shrinker simply skip over inodes
that still contain pages: a76cf1a474d7 ("mm: don't reclaim inodes with
many attached pages").

However, this change had to be reverted in 69056ee6a8a3 ("Revert "mm:
don't reclaim inodes with many attached pages"") because it caused severe
reclaim performance problems: Inodes that sit on the shrinker LRU are
attracting reclaim pressure away from the page cache and toward the VFS. 
If we then permanently exempt sizable portions of this pool from actually
getting reclaimed when looked at, this pressure accumulates as deferred
shrinker work (a mechanism for *temporarily* unreclaimable objects) until
it causes mayhem in the VFS cache pools.

In the bug quoted in 69056ee6a8a3 in particular, the excessive pressure
drove the XFS shrinker into dirty objects, where it caused synchronous,
IO-bound stalls, even as there was plenty of clean page cache that should
have been reclaimed instead.

Another variant of this problem was recently observed, where the kernel
violates cgroups' memory.low protection settings and reclaims page cache
way beyond the configured thresholds.  It was followed by a proposal of a
modified form of the reverted commit above, that implements
memory.low-sensitive shrinker skipping over populated inodes on the LRU
[1].  However, this proposal continues to run the risk of attracting
disproportionate reclaim pressure to a pool of still-used inodes, while
not addressing the more generic reclaim inversion problem outside of a
very specific cgroup application.

[1] https://lore.kernel.org/linux-mm/1578499437-1664-1-git-send-email-laoar.shao@gmail.com/

Solution

This patch fixes the aging inversion described above on !CONFIG_HIGHMEM
systems, without reintroducing the problems associated with excessive
shrinker LRU rotations, by keeping populated inodes off the shrinker LRUs
entirely.

Currently, inodes are kept off the shrinker LRU as long as they have an
elevated i_count, indicating an active user.  Unfortunately, the page
cache cannot simply hold an i_count reference, because unlink() *should*
result in the inode being dropped and its cache invalidated.

Instead, this patch makes iput_final() consult the state of the page cache
and punt the LRU linking to the VM if the inode is still populated; the VM
in turn checks the inode state when it depopulates the page cache, and
adds the inode to the LRU if necessary.

This is not unlike what we do for dirty inodes, which are moved off the
LRU permanently until writeback completion puts them back on (iff still
unused).  We can reuse the same code -- inode_add_lru() - here.

This is also not unlike page reclaim, where the lower VM layer has to
negotiate state with the higher VFS layer.  Follow existing precedence and
handle the inversion as much as possible on the VM side:

- introduce an I_PAGES flag that the VM maintains under the i_lock, so
  that any inode code holding that lock can check the page cache state
  without having to lock and inspect the struct address_space

- introduce inode_pages_set() and inode_pages_clear() to maintain the
  inode LRU state from the VM side, then update all cache mutators to use
  them when populating the first cache entry or clearing the last

With this, the concept of "inodesteal" - where the inode shrinker drops
page cache - is relegated to CONFIG_HIGHMEM systems only.  The VM is in
charge of the cache, the shrinker in charge of struct inode.

Footnotes

- For debuggability, add vmstat counters that track the number of times
  a new cache entry pulls a previously unused inode off the LRU
  (pginoderescue), as well as how many times existing cache deferred an
  LRU addition.  Keep the pginodesteal/kswapd_inodesteal counters for
  backwards compatibility, but they'll just show 0 now.

- Fix /proc/sys/vm/drop_caches to drop shadow entries from the page
  cache.  Not doing so has always been a bit strange, but since most
  people drop cache and metadata cache together, the inode shrinker would
  have taken care of them before - no more, so do it VM-side.

mmotm 2020-05-13-20-30 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-13-20-30 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 5.7-rc5:

Actually, never mind... user error :-)  Will take a look.

Urgh, that's horrible code. That's got plain stac()/clac() calls on
instead of the regular uaccess APIs.

Anybody any clue about what the best way forward here is?

Also, I wonder how we get at memset() with AC set,..

Does it?  If this is from the code in linux-next, then the code does a
user_access_begin/end in csum_and_copy_{from,to}_user, then uses
unsafe_{get,put}_user inside those function itself.  But then they call
csum_partial_copy_generic with the __user casted away, but without any
comment on why this is safe.

Bah, clearly I was looking at the wrong tree. You're right, Al cleaned
it all up.

Let me try and figure out why objtool is unhappy with it.

*groan*, this is one of those CONFIG_PROFILE_ALL_BRANCHES builds. If I
disable that it goes away.

Still trying to untangle the mess it generated, but on first go it
looks like objtool is right, but I'm not sure what went wrong.

The problem is with the +0x113 branch, which is at 0x1d1.

That looks to be:

	if (!likely(user_access_begin(src, len)))
		goto out_err;

Except that the brach profiling stuff confused GCC enough to leak STAC
into the error path or something.

Reproduces for me with gcc-9 and gcc-10.

It looks to me like GCC is doing the right thing.  That likely()
translates to:

#  define likely(x)	(__branch_check__(x, 1, __builtin_constant_p(x)))

which becomes:

#define __branch_check__(x, expect, is_constant) ({			\
			long ______r;					\
			static struct ftrace_likely_data		\
				__aligned(4)				\
				__section(_ftrace_annotated_branch)	\
				______f = {				\
				.data.func = __func__,			\
				.data.file = __FILE__,			\
				.data.line = __LINE__,			\
			};						\
			______r = __builtin_expect(!!(x), expect);	\
			ftrace_likely_update(&______f, ______r,		\
					     expect, is_constant);	\
			______r;					\
		})

Here 'x' is the call to user_access_begin().  It evaluates 'x' -- and
thus calls user_access_begin() -- before the call to
ftrace_likely_update().

So it's working as designed, right?  The likely() just needs to be
changed to likely_notrace().

But if !x (ie we fail user_access_begin()), we should not pass STAC() on
the way to out_err. OTOH if x, we should not be jumping to out_err.

I'm most confused... must not stare at asm for a while.

Yeah, I saw that call to ftrace_likely_update() and got distracted.  I
forgot it's on the uaccess safe list.

From staring at the asm I think the generated code is correct, it's just
that the nested likelys with ftrace profiling cause GCC to converge the
error/success paths.  But objtool doesn't do register value tracking so
it's not smart enough to know that it's safe.

The nested likelys seem like overkill anyway -- user_access_begin() is

If there are no objections to the patch, I can add it to my objtool-core
branch unless anybody else wants to take it.  It only affects
linux-next.

---8<---

From: Josh Poimboeuf <jpoimboe@redhat.com>
Subject: [PATCH] x86/uaccess: Remove redundant likely/unlikely annotations

Since user_access_begin() already has an unlikely() annotation for its
access_ok() check, "if (likely(user_access_begin))" results in nested
likely annotations.  When combined with CONFIG_TRACE_BRANCH_PROFILING,
GCC converges the error/success paths of the nested ifs, using a
register value to distinguish between them.

While the code is technically uaccess safe, it complicates the
branch-profiling generated code.  It also confuses objtool, because it
doesn't do register value tracking, resulting in the following warnings:

  arch/x86/lib/csum-wrappers_64.o: warning: objtool: csum_and_copy_from_user()+0x2a4: call to memset() with UACCESS enabled
  arch/x86/lib/csum-wrappers_64.o: warning: objtool: csum_and_copy_to_user()+0x243: return with UACCESS enabled

The outer likely annotations aren't actually needed anyway, since the
compiler propagates the error path coldness when it inlines
user_access_begin().

I'm surprised that gcc doesn't end up doing the obvious CSE and then
branch following and folding it all away in the end, but your patch is
obviously the right thing to do regardless, so ack on that.

Al - I think this had best go into your uaccess cleanup branch with
that csum-wrapper update, to avoid any unnecessary conflicts or

------------------------------------------------------
From: Joe Perches <joe@perches.com>
Subject: get_maintainer: fix unexpected behavior for path/to//file (double slashes)

get_maintainer behaves differently if there is a double sequential forward
slash in a filename because the total number of slashes in a filename is
used to match MAINTAINERS file patterns.

For example:

# (with double slash)
$ ./scripts/get_maintainer.pl -f drivers/gpu/drm//lima
David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS)
Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS,commit_signer:3/42=7%)
Qiang Yu <yuq825@gmail.com> (commit_signer:36/42=86%,authored:24/42=57%)
Vasily Khoruzhick <anarsoul@gmail.com> (commit_signer:26/42=62%)
Krzysztof Kozlowski <krzk@kernel.org> (commit_signer:5/42=12%,authored:5/42=12%)
Emil Velikov <emil.velikov@collabora.com> (commit_signer:4/42=10%)
dri-devel@lists.freedesktop.org (open list:DRM DRIVERS)
linux-kernel@vger.kernel.org (open list)

# (without double slash)
$ ./scripts/get_maintainer.pl -f drivers/gpu/drm/lima
Qiang Yu <yuq825@gmail.com> (maintainer:DRM DRIVERS FOR LIMA)
David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS)
Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS)
dri-devel@lists.freedesktop.org (open list:DRM DRIVERS FOR LIMA)
lima@lists.freedesktop.org (moderated list:DRM DRIVERS FOR LIMA)
linux-kernel@vger.kernel.org (open list)

So reduce consecutive double slashes to a single slash
by using File::Spec->canonpath().

from: https://perldoc.perl.org/File/Spec/Unix.html

canonpath()

No physical check on the filesystem, but a logical cleanup of a path.  On
UNIX eliminates successive slashes and successive "/.".

------------------------------------------------------
From: Joerg Roedel <jroedel@suse.de>
Subject: mm: add functions to track page directory modifications

Patch series "mm: Get rid of vmalloc_sync_(un)mappings()", v3.

After the recent issue with vmalloc and tracing code[1] on x86 and a long
history of previous issues related to the vmalloc_sync_mappings()
interface, I thought the time has come to remove it.  Please see [2], [3],
and [4] for some other issues in the past.

The patches add tracking of page-table directory changes to the vmalloc
and ioremap code.  Depending on which page-table levels changes have been
made, a new per-arch function is called: arch_sync_kernel_mappings().

On x86-64 with 4-level paging, this function will not be called more than
64 times in a systems runtime (because vmalloc-space takes 64 PGD entries
which are only populated, but never cleared).

As a side effect this also allows to get rid of vmalloc faults on x86,
making it safe to touch vmalloc'ed memory in the page-fault handler.  Note
that this potentially includes per-cpu memory.


This patch (of 7):

Add page-table allocation functions which will keep track of changed
directory entries.  They are needed for new PGD, P4D, PUD, and PMD entries
and will be used in vmalloc and ioremap code to decide whether any changes
in the kernel mappings need to be synchronized between page-tables in the
system.

Track at which levels in the page-table entries were modified by
vmap/vunmap.  After the page-table has been modified, use that information
do decide whether the new arch_sync_kernel_mappings() needs to be called.

mappings are now synchronized when they are created or teared down.

Remove all callers and function definitions.

Subject: x86: bitops: fix build regression

This is easily reproducible via CC=clang+CONFIG_STAGING=y+CONFIG_VT6656=m.

It turns out that if your config tickles __builtin_constant_p via
differences in choices to inline or not, these statements produce invalid
assembly:

$ cat foo.c
long a(long b, long c) {
  asm("orb	%1, %0" : "+q"(c): "r"(b));
  return c;
}
$ gcc foo.c
foo.c: Assembler messages:
foo.c:2: Error: `%rax' not allowed with `orb'

Use the `%b` "x86 Operand Modifier" to instead force register allocation
to select a lower-8-bit GPR operand.

The "q" constraint only has meaning on -m32 otherwise is treated as
"r". Not all GPRs have low-8-bit aliases for -m32.

------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: don't include asm/pgtable.h if linux/mm.h is already included

Patch series "mm: consolidate definitions of page table accessors", v2.

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once.  For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g. 

static inline unsigned long pmd_index(unsigned long address)
{
        return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
        return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.  


This patch (of 12):

The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g.  pte_alloc() and
pmd_alloc().  So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.

The include statements in such cases are remove with a simple loop:

	for f in $(git grep -l "include <linux/mm.h>") ; do
		sed -i -e '/include <asm\/pgtable.h>/ d' $f
	done

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: introduce include/linux/pgtable.h

The include/linux/pgtable.h is going to be the home of generic page table
manipulation functions.

Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and
make the latter include asm/pgtable.h.

------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: reorder includes after introduction of linux/pgtable.h

The replacement of <asm/pgrable.h> with <linux/pgtable.h> made the include
of the latter in the middle of asm includes.  Fix this up with the aid of
the below script and manual adjustments here and there.

	import sys
	import re

	if len(sys.argv) is not 3:
	    print "USAGE: %s <file> <header>" % (sys.argv[0])
	    sys.exit(1)

	hdr_to_move="#include <linux/%s>" % sys.argv[2]
	moved = False
	in_hdrs = False

	with open(sys.argv[1], "r") as f:
	    lines = f.readlines()
	    for _line in lines:
		line = _line.rstrip('
')
		if line == hdr_to_move:
		    continue
		if line.startswith("#include <linux/"):
		    in_hdrs = True
		elif not moved and in_hdrs:
		    moved = True
		    print hdr_to_move
		print line

The patch titled
     Subject: csky: replace definitions of __pXd_offset() with pXd_index()
has been added to the -mm tree.  Its filename is
     csky-replace-definitions-of-__pxd_offset-with-pxd_index.patch

This patch should soon appear at
    http://ozlabs.org/~akpm/mmots/broken-out/csky-replace-definitions-of-__pxd_offset-with-pxd_index.patch
and later at
    http://ozlabs.org/~akpm/mmotm/broken-out/csky-replace-definitions-of-__pxd_offset-with-pxd_index.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: Mike Rapoport <rppt@linux.ibm.com>
Subject: csky: replace definitions of __pXd_offset() with pXd_index()

All architectures use pXd_index() to get an entry in the page table page
corresponding to a virtual address.

Align csky with other architectures.

Subject: m68k/mm/motorola: move comment about page table allocation funcitons

The comment about page table allocation functions resides in
include/asm/motorola_pgtable.h while the functions live in
include/asm/motorola_pgaloc.h.

Move the comment close to the code.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: m68k/mm: move {cache,nocahe}_page() definitions close to their user

The cache_page() and nocache_page() functions are only used by the
motorola MMU variant for setting caching attributes for the page table
pages.

Move the definitions of these functions from
arch/m68k/include/asm/motorola_pgtable.h closer to their usage in
arch/m68k/mm/motorola.c and drop unused definition in
arch/m68k/include/asm/mcf_pgtable.h.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: x86/mm: simplify init_trampoline() and surrounding logic

There are three cases for the trampoline initialization:
* 32-bit does nothing
* 64-bit with kaslr disabled simply copies a PGD entry from the direct map
  to the trampoline PGD
* 64-bit with kaslr enabled maps the real mode trampoline at PUD level

These cases are currently differentiated by a bunch of ifdefs inside
asm/include/pgtable.h and the case of 64-bits with kaslr on uses
pgd_index() helper.

Replacing the ifdefs with a static function in arch/x86/mm/init.c gives
clearer code and allows moving pgd_index() to the generic implementation
in include/linux/pgtable.h

Subject: mm: pgtable: add shortcuts for accessing kernel PMD and PTE

The powerpc 32-bit implementation of pgtable has nice shortcuts for
accessing kernel PMD and PTE for a given virtual address.  Make this
helpers available for all architectures.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: consolidate pte_index() and pte_offset_*() definitions

All architectures define pte_index() as

	(address >> PAGE_SHIFT) & (PTRS_PER_PTE - 1)

and all architectures define pte_offset_kernel() as an entry in the array
of PTEs indexed by the pte_index().

For the most architectures the pte_offset_kernel() implementation relies
on the availability of pmd_page_vaddr() that converts a PMD entry value to
the virtual address of the page containing PTEs array.

Let's move x86 definitions of the PTE accessors to the generic place in
<linux/pgtable.h> and then simply drop the respective definitions from the
other architectures.

The architectures that didn't provide pmd_page_vaddr() are updated to have
that defined.

The generic implementation of pte_offset_kernel() can be overridden by an
architecture and alpha makes use of this because it has special ordering
requirements for its version of pte_offset_kernel().

------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: consolidate pmd_index() and pmd_offset() definitions

All architectures define pmd_index() as

	(address >> PMD_SHIFT) & (PTRS_PER_PMD - 1)

and all architectures that have at least three-level page tables define
pmd_offset() as an entry in the array of PMDs indexed by the pmd_index().

For the most architectures the pmd_offset() implementation relies on the
availability of pud_page_vaddr() that converts a PMD entry value to the
virtual address of the page containing PMD array.

Let's use such implementation as a generic and drop most of the
definitions of pmd_index() and pmd_offset() in <asm/pgtable.h> files.

The architectures that didn't provide pud_page_vaddr() are updated to have
that defined.

The generic implementation can be overridden by an architecture and this
ability is currently in use by there architectures:
* alpha has special requirements for memory access ordering
* arm has custom definition of folded 2-level page tables
* s390 has custom definitions of all page table accessors

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: consolidate pud_index() and pud_offset() definitions

All architectures that have at least four-level page tables define
pud_offset() as an entry in the array of PUDs indexed by the pud_index(),
where pud_index() is

	(address >> PUD_SHIFT) & (PTRS_PER_PUD - 1)

For the most architectures the pud_offset() implementation relies on the
availability of pud_page_vaddr() that converts a PUD entry value to the
virtual address of the page containing PUD array.

Let's use such implementation as a generic and drop most of the
definitions of pud_index() and pud_offset() in <asm/pgtable.h> files.

The architectures that didn't provide pud_page_vaddr() are updated to have
that defined.

The generic implementation can be overridden by an architecture and this
ability is currently in use by there architectures:
* s390 has custom definitions of all page table accessors

[Andrew Morton]

The patch titled
     Subject: mm: consolidate pgd_index() and pgd_offset{_k}() definitions
has been added to the -mm tree.  Its filename is
     mm-consolidate-pgd_index-and-pgd_offset_k-definitions.patch

This patch should soon appear at
    http://ozlabs.org/~akpm/mmots/broken-out/mm-consolidate-pgd_index-and-pgd_offset_k-definitions.patch
and later at
    http://ozlabs.org/~akpm/mmotm/broken-out/mm-consolidate-pgd_index-and-pgd_offset_k-definitions.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: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: consolidate pgd_index() and pgd_offset{_k}() definitions

All architectures tables define pgd_offset() as an entry in the array of
PGDs indexed by the pgd_index(), where pgd_index() is

	(address >> PGD_SHIFT) & (PTRS_PER_PGD - 1)

For the most cases, the pgd_offset() uses mm->pgd as the pointer to the
top-level page directory and the pgd_offset_k() is a helper that presumes
that mm == &init_mm.

Use x86 implementation as the generic one and remove redundant definitions
of PGD accessors in most of arch/*/include/asm/pgtable.h

The generic implementation can be overridden by an architecture and this
ability is currently in use by there architectures:
* ia64 has custom implementation of pgd_index()
* s390 has custom definitions of all page table accessors

From: Charan Teja Reddy <charante@codeaurora.org>
Subject: mm, page_alloc: reset the zone->watermark_boost early

Updating the zone watermarks by any means, like min_free_kbytes,
water_mark_scale_factor etc, when ->watermark_boost is set will result in
higher low and high watermarks than the user asked.

Below are the steps to reproduce the problem on system setup of Android
kernel running on Snapdragon hardware.

1) Default settings of the system are as below:

   #cat /proc/sys/vm/min_free_kbytes = 5162
   #cat /proc/zoneinfo | grep -e boost -e low -e "high " -e min -e Node
	Node 0, zone   Normal
		min      797
		low      8340
		high     8539

2) Monitor the zone->watermark_boost(by adding a debug print in the
   kernel) and whenever it is greater than zero value, write the same
   value of min_free_kbytes obtained from step 1.

   #echo 5162 > /proc/sys/vm/min_free_kbytes

3) Then read the zone watermarks in the system while the
   ->watermark_boost is zero.  This should show the same values of
   watermarks as step 1 but shown a higher values than asked.

   #cat /proc/zoneinfo | grep -e boost -e low -e "high " -e min -e Node
	Node 0, zone   Normal
		min      797
		low      21148
		high     21347

These higher values are because of updating the zone watermarks using the
macro min_wmark_pages(zone) which also adds the zone->watermark_boost.

	#define min_wmark_pages(z) (z->_watermark[WMARK_MIN] +
					z->watermark_boost)

So the steps that lead to the issue are:

1) On the extfrag event, watermarks are boosted by storing the required
   value in ->watermark_boost.

2) User tries to update the zone watermarks level in the system through
   min_free_kbytes or watermark_scale_factor.

3) Later, when kswapd woke up, it resets the zone->watermark_boost to
   zero.

In step 2), we use the min_wmark_pages() macro to store the watermarks
in the zone structure thus the values are always offsetted by
->watermark_boost value. This can be avoided by resetting the
->watermark_boost to zero before it is used.

mmotm 2020-05-15-16-29 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-15-16-29 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: Mike Rapoport <rppt@linux.ibm.com>
Subject: microblaze: fix page table traversal in setup_rt_frame()

The replacement of long folded page table traversal with the direct access
to PMD entry wrongly used the kernel page table in setup_rt_frame()
function instead of the process (current->mm) page table.

Fix it.

------------------------------------------------------
From: Yang Shi <yang.shi@linux.alibaba.com>
Subject: mm: khugepaged: remove error message when checking external pins

When running khugepaged with higher frequency (for example, set
scan_sleep_millisecs to 0), the below error message was reported:

khugepaged: expected_refcount (1024) > refcount (512)
page:ffffd75784258000 count:511 mapcount:1 mapping:ffff968de06c7421 index:0x7fa288600
 compound_mapcount: 0
 flags: 0x17fffc00009003c(uptodate|dirty|lru|active|head|swapbacked)
 raw: 017fffc00009003c ffffd7578ba70788 ffffd7578bdb5148 ffff968de06c7421
 raw: 00000007fa288600 0000000000000000 000001ff00000000 ffff968e5e7d6000
 page dumped because: Unexpected refcount
 page->mem_cgroup:ffff968e5e7d6000

This is introduced by allowing collapsing fork shared and PTE-mapped
THPs.  The check may run into the below race:

Assuming parent process forked child process, then they do

	CPU A		CPU B			CPU C
	-----		-----			-----
Parent			Child			khugepaged

MADV_DONTNEED
  split huge pmd
  Double mapped
			MADV_DONTNEED
			  zap_huge_pmd
			    remove_page_rmap
			      Clear double map
						khugepaged_scan_pmd(parent)
						  check mapcount and refcount
						  --> total_mapcount > refcount
			      dec mapcount

The issue can be reproduced by the below test program.

---8<---
void main()
{
        void *addr;
        int ret;
        pid_t pid;

        addr = memalign(ALIGN, 2 * 1024 * 1024);
        if (!addr) {
                printf("malloc failed
");
                return;
        }

        ret = madvise(addr, 2 * 1024 * 1024, MADV_HUGEPAGE);
        if (ret < 0) {
                printf("madvise failed
");
                return;
        }

        memset(addr, 0xdeadbeef, 2 * 1024 * 1024);

        pid = fork();

        if (pid == 0) {
                /* Child process */
                ret = madvise(addr + (2 * 1024 * 1024) - 4096, 4096, MADV_DONTNEED);
                if (ret < 0) {
                        printf("madvise failed in child
");
                        return;
                }
                sleep(120);
        } else if (pid > 0) {
                sleep(5);
                /* Parent process */
                ret = madvise(addr, 2 * 1024 * 1024, MADV_DONTNEED);
                if (ret < 0) {
                        printf("madvise failed in parent
");
                        return;
                }
        } else {
                printf("fork failed
");
                return;
        }

        sleep(120);
}
---8<---

So, total_mapcount > refcount seems not unexpected due to the inherent
race.  Removed the error message even though it is protected by
CONFIG_VM_DEBUG since we have to live with the race and AFAIK some
distros may have CONFIG_VM_DEBUG enabled dy default.

Since such case is ephemeral we could always try collapse the area again
later, so it sounds not harmful.  But, it might report false positive if
the page has excessive GUP pins (i.e. 512), however it might be not that
bad since the same check will be done later.  I didn't figure out a
simple way to prevent the false positive.

Added some notes to elaborate the race and the consequence as well.

Subject: mm/page_alloc: restrict and formalize compound_page_dtors[]

Restrict elements in compound_page_dtors[] array per NR_COMPOUND_DTORS and
explicitly position them according to enum compound_dtor_id.  This
improves protection against possible misalignment between
compound_page_dtors[] and enum compound_dtor_id later on.

Subject: hugetlbfs: get unmapped area below TASK_UNMAPPED_BASE for hugetlbfs

In a 32-bit program, running on arm64 architecture.  When the address
space below mmap base is completely exhausted, shmat() for huge pages will
return ENOMEM, but shmat() for normal pages can still success on no-legacy
mode.  This seems not fair.

For normal pages, the calling trace of get_unmapped_area() is:

	=> mm->get_unmapped_area()
	if on legacy mode,
		=> arch_get_unmapped_area()
			=> vm_unmapped_area()
	if on no-legacy mode,
		=> arch_get_unmapped_area_topdown()
			=> vm_unmapped_area()

For huge pages, the calling trace of get_unmapped_area() is:

	=> file->f_op->get_unmapped_area()
		=> hugetlb_get_unmapped_area()
			=> vm_unmapped_area()

To solve this issue, we only need to make hugetlb_get_unmapped_area() take
the same way as mm->get_unmapped_area().  Add *bottomup() and *topdown()
for hugetlbfs, and check current mm->get_unmapped_area() to decide which
one to use.  If mm->get_unmapped_area is equal to
arch_get_unmapped_area_topdown(), hugetlb_get_unmapped_area() calls
topdown routine, otherwise calls bottomup routine.

From: Kees Cook <keescook@chromium.org>
Subject: exec: change uselib(2) IS_SREG() failure to EACCES

Patch series "Relocate execve() sanity checks".

While looking at the code paths for the proposed O_MAYEXEC flag, I saw
some things that looked like they should be fixed up.

  exec: Change uselib(2) IS_SREG() failure to EACCES
	This just regularizes the return code on uselib(2).

  exec: Relocate S_ISREG() check
	This moves the S_ISREG() check even earlier than it was already.

  exec: Relocate path_noexec() check
	This adds the path_noexec() check to the same place as the
	S_ISREG() check.

  fs: Include FMODE_EXEC when converting flags to f_mode
	This seemed like an oversight, but I suspect there is some
	reason I couldn't find for why FMODE_EXEC doesn't get set in
	f_mode and just stays in f_flags.


This patch (of 4):

Change uselib(2)' S_ISREG() error return to EACCES instead of EINVAL so
the behavior matches execve(2), and the seemingly documented value.  The
"not a regular file" failure mode of execve(2) is explicitly
documented[1], but it is not mentioned in uselib(2)[2] which does,
however, say that open(2) and mmap(2) errors may apply.  The documentation
for open(2) does not include a "not a regular file" error[3], but mmap(2)
does[4], and it is EACCES.

From: Kees Cook <keescook@chromium.org>
Subject: exec: relocate S_ISREG() check

The execve(2)/uselib(2) syscalls have always rejected non-regular files. 
Recently, it was noticed that a deadlock was introduced when trying to
execute pipes, as the S_ISREG() test was happening too late.  This was
fixed in commit 73601ea5b7b1 ("fs/open.c: allow opening only regular files
during execve()"), but it was added after inode_permission() had already
run, which meant LSMs could see bogus attempts to execute non-regular
files.  Move the test earlier.

Also include a comment with the redundant S_ISREG() checks at the end of
execve(2)/uselib(2) to note that they are present to avoid any mistakes.

Finally, instead of dereferencing the inode, use dcache for S_ISREG()
test.

My notes on the call path, and related arguments, checks, etc:

do_open_execat()
    struct open_flags open_exec_flags = {
        .open_flag = O_LARGEFILE | O_RDONLY | __FMODE_EXEC, ...
    do_filp_open(dfd, filename, open_flags)
        path_openat(nameidata, open_flags, flags)
            /* f_mode populated from open_flags in alloc_empty_file() */
            file = alloc_empty_file(open_flags, current_cred());

		/* new location of FMODE_EXEC vs S_ISREG() test */

Subject: exec: relocate path_noexec() check

The path_noexec() check, like the regular file check, was happening too
late, letting LSMs see impossible execve()s.  Check it earlier as well and
collect the redundant fs/exec.c path_noexec() test under the same
robustness comment as the S_ISREG() check.

Include FMODE_EXEC when building the f_mode field, so that code can
actually test the correct field and values.  Only three places actually
examine f_flags for FMODE_EXEC:

From: John Hubbard <jhubbard@nvidia.com>
Subject: ivtv: convert get_user_pages() --> pin_user_pages()

This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA),
using the categorization from [1].  That means that it's time to convert
the get_user_pages*() + put_page() calls to pin_user_pages*() +
unpin_user_pages() calls.

There is some helpful background in [2]: basically, this is a small part
of fixing a long-standing disconnect between pinning pages, and file
systems' use of those pages.

Subject: rapidio: fix an error in get_user_pages_fast() error handling

In the case of get_user_pages_fast() returning fewer pages than requested,
rio_dma_transfer() does not quite do the right thing.  It attempts to
release all the pages that were requested, rather than just the pages that
were pinned.

Fix the error handling so that only the pages that were successfully
pinned are released.

From: John Hubbard <jhubbard@nvidia.com>
Subject: rapidio: convert get_user_pages() --> pin_user_pages()

This code was using get_user_pages_fast(), in a "Case 2" scenario
(DMA/RDMA), using the categorization from [1].  That means that it's time
to convert the get_user_pages_fast() + put_page() calls to
pin_user_pages_fast() + unpin_user_pages() calls.

There is some helpful background in [2]: basically, this is a small
part of fixing a long-standing disconnect between pinning pages, and
file systems' use of those pages.

[1] Documentation/core-api/pin_user_pages.rst

From: Guoqing Jiang <guoqing.jiang@cloud.ionos.com>
Subject: include/linux/pagemap.h: introduce attach/detach_page_private

Patch series "Introduce attach/detach_page_private to cleanup code".


This patch (of 10):

The logic in attach_page_buffers and __clear_page_buffers are quite
paired, but

1. they are located in different files.

2. attach_page_buffers is implemented in buffer_head.h, so it could be
   used by other files. But __clear_page_buffers is static function in
   buffer.c and other potential users can't call the function, md-bitmap
   even copied the function.

So, introduce the new attach/detach_page_private to replace them.  With
the new pair of function, we will remove the usage of attach_page_buffers
and __clear_page_buffers in next patches.  Thanks for suggestions about
the function name from Alexander Viro, Andreas Grünbacher, Christoph
Hellwig and Matthew Wilcox.

Subject: mm: simplify calling a compound page destructor

None of the three callers of get_compound_page_dtor() want to know the
value; they just want to call the function.  Replace it with
destroy_compound_page() which calls the dtor for them.

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", v3.

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.


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 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 sever, which should be fine for its
only two users: /proc/meminfo and HyperV balloon driver's status trace per
second.

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.

access in kasan_unmap_early_shadow_vmalloc() because the name used in
powerpc for the same helper was different from the generic one.

Subject: mm: use only pidfd for process_madvise syscall

Based on discussion[1], people didn't feel we need to support both
pid and pidfd for every new coming API[2] so this patch keeps only
pidfd. This patch also changes flags's type with "unsigned int".

------------------------------------------------------
From: Rafael Aquini <aquini@redhat.com>
Subject: kernel: add panic_on_taint

Analogously to the introduction of panic_on_warn, this patch introduces a
kernel option named panic_on_taint in order to provide a simple and
generic way to stop execution and catch a coredump when the kernel gets
tainted by any given flag.

This is useful for debugging sessions as it avoids having to rebuild the
kernel to explicitly add calls to panic() into the code sites that
introduce the taint flags of interest.  For instance, if one is interested
in proceeding with a post-mortem analysis at the point a given code path
is hitting a bad page (i.e.  unaccount_page_cache_page(), or slab_bug()),
a coredump can be collected by rebooting the kernel with
'panic_on_taint=0x20' amended to the command line.

Another, perhaps less frequent, use for this option would be as a means
for assuring a security policy case where only a subset of taints, or no
single taint (in paranoid mode), is allowed for the running system.  The
optional switch 'nousertaint' is handy in this particular scenario, as it
will avoid userspace induced crashes by writes to sysctl interface
/proc/sys/kernel/tainted causing false positive hits for such policies.

From: Christoph Hellwig <hch@lst.de>
Subject: arm: fix the flush_icache_range arguments in set_fiq_handler

Patch series "sort out the flush_icache_range mess", v2.

flush_icache_range is mostly used for kernel address, except for the
following cases:

 - the nommu brk and mmap implementations,
 - the read_code helper that is only used for binfmt_flat, binfmt_elf_fdpic,
   and binfmt_aout including the broken ia32 compat version
 - binfmt_flat itself,

none of which really are used by a typical MMU enabled kernel, as a.out
can only be build for alpha and m68k to start with.

But strangely enough commit ae92ef8a4424 ("PATCH] flush icache in correct
context") added a "set_fs(KERNEL_DS)" around the flush_icache_range call
in the module loader, because apparently m68k assumed user pointers.

This series first cleans up the cacheflush implementations, largely by
switching as much as possible to the asm-generic version after a few
preparations, then moves the misnamed current flush_icache_user_range to a
new name, to finally introduce a real flush_icache_user_range to be used
for the above use cases to flush the instruction cache for a userspace
address range.  The last patch then drops the set_fs in the module code
and moves it into the m68k implementation.


This patch (of 29):

The arguments passed look bogus, try to fix them to something that seems
to make sense.

cacheflush.h uses a somewhat to generic include guard name that clashes
with various arch files.  Use a more specific one.

Subject: asm-generic: don't include <linux/mm.h> in cacheflush.h

This seems to lead to some crazy include loops when using
asm-generic/cacheflush.h on more architectures, so leave it to the arch
header for now.

From: Christoph Hellwig <hch@lst.de>
Subject: asm-generic: improve the flush_dcache_page stub

There is a magic ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE cpp symbol that
guards non-stub availability of flush_dcache_pagge.  Use that to
check if flush_dcache_pagg is implemented.

Subject: c6x: use asm-generic/cacheflush.h

C6x needs almost no cache flushing routines of its own.  Rely on
asm-generic/cacheflush.h for the defaults.

Microblaze needs almost no cache flushing routines of its own.  Rely on
asm-generic/cacheflush.h for the defaults.

From: Christoph Hellwig <hch@lst.de>
Subject: powerpc: use asm-generic/cacheflush.h

Power needs almost no cache flushing routines of its own.  Rely on
asm-generic/cacheflush.h for the defaults.

Also remove the pointless __KERNEL__ ifdef while we're at it.

From: Christoph Hellwig <hch@lst.de>
Subject: mm: rename flush_icache_user_range to flush_icache_user_page

The function currently known as flush_icache_user_range only operates
on a single page.  Rename it to flush_icache_user_page as we'll need
the name flush_icache_user_range for something else soon.

Rename the current flush_icache_range to flush_icache_user_range as per
commit ae92ef8a4424 ("PATCH] flush icache in correct context") there seems
to be an assumption that it operates on user addresses.  Add a
flush_icache_range around it that for now is a no-op.

Subject: module: move the set_fs hack for flush_icache_range to m68k

flush_icache_range generally operates on kernel addresses, but for some
reason m68k needed a set_fs override.  Move that into the m68k code insted
of keeping it in the module loader.

[alternative-merged] mm-slub-add-panic_on_error-to-the-debug-facilities.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: mm: slub: add panic_on_error to the debug facilities
has been removed from the -mm tree.  Its filename was
     mm-slub-add-panic_on_error-to-the-debug-facilities.patch

This patch was dropped because an alternative patch was merged

------------------------------------------------------
From: Rafael Aquini <aquini@redhat.com>
Subject: mm: slub: add panic_on_error to the debug facilities

Sometimes it is desirable to override SLUB's debug facilities default
behavior upon stumbling on a cache or object error and just stop the
execution in order to grab a coredump, at the error-spotting time, instead
of trying to fix the issue and report in an attempt to keep the system
rolling.

This patch introduces a new debug flag SLAB_PANIC_ON_ERROR, along with its
related SLUB-machinery, in order to extend current slub_debug facilites
and provide the aforementioned behavior override.

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup: move __get_user_pages_fast() down a few lines in gup.c

Patch series "mm/gup, drm/i915: refactor gup_fast, convert to
pin_user_pages()".

In order to convert the drm/i915 driver from get_user_pages() to
pin_user_pages(), a FOLL_PIN equivalent of __get_user_pages_fast() was
required.  That led to refactoring __get_user_pages_fast(), with the
following goals:

1) As above: provide a pin_user_pages*() routine for drm/i915 to call,
   in place of __get_user_pages_fast(),

2) Get rid of the gup.c duplicate code for walking page tables with
   interrupts disabled. This duplicate code is a minor maintenance
   problem anyway.

3) Make it easy for an upcoming patch from Souptick, which aims to
   convert __get_user_pages_fast() to use a gup_flags argument, instead
   of a bool writeable arg.  Also, if this series looks good, we can
   ask Souptick to change the name as well, to whatever the consensus
   is. My initial recommendation is: get_user_pages_fast_only(), to
   match the new pin_user_pages_only().


This patch (of 4):

This is in order to avoid a forward declaration of
internal_get_user_pages_fast(), in the next patch.

This is code movement only--all generated code should be identical.

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup: refactor and de-duplicate gup_fast() code

There were two nearly identical sets of code for gup_fast() style of
walking the page tables with interrupts disabled.  This has lead to the
usual maintenance problems that arise from having duplicated code.

There is already a core internal routine in gup.c for gup_fast(), so just
enhance it very slightly: allow skipping the fall-back to "slow" (regular)
get_user_pages(), via the new FOLL_FAST_ONLY flag.  Then, just call
internal_get_user_pages_fast() from __get_user_pages_fast(), and adjust
the API to match pre-existing API behavior.

There is a change in behavior from this refactoring: the nested form of
interrupt disabling is used in all gup_fast() variants now.  That's
because there is only one place that interrupt disabling for page walking
is done, and so the safer form is required.  This should, if anything,
eliminate possible (rare) bugs, because the non-nested form of enabling
interrupts was fragile at best.

Subject: drm/i915: convert get_user_pages() --> pin_user_pages()

This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA),
using the categorization from [1].  That means that it's time to convert
the get_user_pages*() + put_page() calls to pin_user_pages*() +
unpin_user_pages() calls.

There is some helpful background in [2]: basically, this is a small part
of fixing a long-standing disconnect between pinning pages, and file
systems' use of those pages.

Subject: kasan: disable branch tracing for core runtime

During early boot, while KASAN is not yet initialized, it is possible to
enter reporting code-path and end up in kasan_report().  While
uninitialized, the branch there prevents generating any reports, however,
under certain circumstances when branches are being traced
(TRACE_BRANCH_PROFILING), we may recurse deep enough to cause kernel
reboots without warning.

To prevent similar issues in future, we should disable branch tracing for
the core runtime.

From: Arnd Bergmann <arnd@arndb.de>
Subject: sh: include linux/time_types.h for sockios

Using the socket ioctls on arch/sh (and only there) causes build time
problems when __kernel_old_timeval/__kernel_old_timespec are not already
visible to the compiler.

Add an explict include line for the header that defines these
structures.

------------------------------------------------------
From: Charan Teja Reddy <charante@codeaurora.org>
Subject: mm, page_alloc: skip ->waternark_boost for atomic order-0 allocations

When boosting is enabled, it is observed that rate of atomic order-0
allocation failures are high due to the fact that free levels in the
system are checked with ->watermark_boost offset.  This is not a problem
for sleepable allocations but for atomic allocations which looks like
regression.

This problem is seen frequently on system setup of Android kernel running
on Snapdragon hardware with 4GB RAM size.  When no extfrag event occurred
in the system, ->watermark_boost factor is zero, thus the watermark
configurations in the system are:

   _watermark = (
          [WMARK_MIN] = 1272, --> ~5MB
          [WMARK_LOW] = 9067, --> ~36MB
          [WMARK_HIGH] = 9385), --> ~38MB
   watermark_boost = 0

After launching some memory hungry applications in Android which can cause
extfrag events in the system to an extent that ->watermark_boost can be
set to max i.e.  default boost factor makes it to 150% of high watermark.

   _watermark = (
          [WMARK_MIN] = 1272, --> ~5MB
          [WMARK_LOW] = 9067, --> ~36MB
          [WMARK_HIGH] = 9385), --> ~38MB
   watermark_boost = 14077, -->~57MB

With default system configuration, for an atomic order-0 allocation to
succeed, having free memory of ~2MB will suffice.  But boosting makes the
min_wmark to ~61MB thus for an atomic order-0 allocation to be successful
system should have minimum of ~23MB of free memory(from calculations of
zone_watermark_ok(), min = 3/4(min/2)).  But failures are observed despite
system is having ~20MB of free memory.  In the testing, this is
reproducible as early as first 300secs since boot and with further lowram
configurations(<2GB) it is observed as early as first 150secs since boot.

These failures can be avoided by excluding the ->watermark_boost in
watermark calculations for atomic order-0 allocations.

Subject: mm: return EBADF if pidfd is invalid

This patch makes returning of EBADF when the fd passed as argument is
invalid. The implementaion relies on pidfd_get_pid's error return.

This patch also fixes syscall declare part since we removed pid support.

Subject: MAINTAINERS: update email address for Naoya Horiguchi

My email address has changed due to system upgrade, so please update it in
MAINTAINERS list.  My old address (n-horiguchi@ah.jp.nec.com) will be
still active for a few months.

Note that my email system has some encoding issue and can't send patches
in raw format via git-send-email.  So patches from me will be delivered
via my free address (nao.horiguchi@gmail.com) or GitHub.

The mm-of-the-moment snapshot 2020-05-19-21-47 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 2020-05-19-21-47 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-19-21-47 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: Ben Widawsky <ben.widawsky@intel.com>
Subject: mm: add comments on pglist_data zones

While making other modifications it was easy to confuse the two struct
members node_zones and node_zonelists.  For those already familiar with
the code, this might seem to be a silly patch, but it's quite helpful to
disambiguate the similar-sounding fields

While here, add a small comment on why nr_zones isn't simply MAX_NR_ZONES

From: Nick Desaulniers <ndesaulniers@google.com>
Subject: Makefile: support compressed debug info

As debug information gets larger and larger, it helps significantly save
the size of vmlinux images to compress the information in the debug
information sections.  Note: this debug info is typically split off from
the final compressed kernel image, which is why vmlinux is what's used in
conjunction with GDB.  Minimizing the debug info size should have no
impact on boot times, or final compressed kernel image size.

All of the debug sections will have a `C` flag set.

From: Daniel Jordan <daniel.m.jordan@oracle.com>
Subject: padata: remove exit routine

Patch series "padata: parallelize deferred page init", v2.

Deferred struct page init is a bottleneck in kernel boot--the biggest for
us and probably others.  Optimizing it maximizes availability for
large-memory systems and allows spinning up short-lived VMs as needed
without having to leave them running.  It also benefits bare metal
machines hosting VMs that are sensitive to downtime.  In projects such as
VMM Fast Restart[1], where guest state is preserved across kexec reboot,
it helps prevent application and network timeouts in the guests.

So, multithread deferred init to take full advantage of system memory
bandwidth.

Extend padata, a framework that handles many parallel singlethreaded jobs,
to handle multithreaded jobs as well by adding support for splitting up
the work evenly, specifying a minimum amount of work that's appropriate
for one helper thread to do, load balancing between helpers, and
coordinating them.  More documentation in patches 4 and 7.

This series is the first step in a project to address other memory
proportional bottlenecks in the kernel such as pmem struct page init, vfio
page pinning, hugetlb fallocate, and munmap.  Deferred page init doesn't
require concurrency limits, resource control, or priority adjustments like
these other users will because it happens during boot when the system is
otherwise idle and waiting for page init to finish.

This has been run on a variety of x86 systems and speeds up kernel boot by
3% to 49%, saving up to 1.6 out of 4 seconds.  Patch 5 has more numbers.


This patch (of 7):

padata_driver_exit() is unnecessary because padata isn't built as a module
and doesn't exit.

padata's init routine will soon allocate memory, so getting rid of the
exit function now avoids pointless code to free it.

Subject: padata: initialize earlier

padata will soon initialize the system's struct pages in parallel, so it
needs to be ready by page_alloc_init_late().

The error return from padata_driver_init() triggers an initcall warning,
so add a warning to padata_init() to avoid silent failure.

From: Daniel Jordan <daniel.m.jordan@oracle.com>
Subject: padata: allocate work structures for parallel jobs from a pool

padata allocates per-CPU, per-instance work structs for parallel jobs.  A
do_parallel call assigns a job to a sequence number and hashes the number
to a CPU, where the job will eventually run using the corresponding work.

This approach fit with how padata used to bind a job to each CPU
round-robin, makes less sense after commit bfde23ce200e6 ("padata: unbind
parallel jobs from specific CPUs") because a work isn't bound to a
particular CPU anymore, and isn't needed at all for multithreaded jobs
because they don't have sequence numbers.

Replace the per-CPU works with a preallocated pool, which allows sharing
them between existing padata users and the upcoming multithreaded user. 
The pool will also facilitate setting NUMA-aware concurrency limits with
later users.

The pool is sized according to the number of possible CPUs.  With this
limit, MAX_OBJ_NUM no longer makes sense, so remove it.

If the global pool is exhausted, a parallel job is run in the current task
instead to throttle a system trying to do too much in parallel.

From: Daniel Jordan <daniel.m.jordan@oracle.com>
Subject: padata: add basic support for multithreaded jobs

Sometimes the kernel doesn't take full advantage of system memory
bandwidth, leading to a single CPU spending excessive time in
initialization paths where the data scales with memory size.

Multithreading naturally addresses this problem.

Extend padata, a framework that handles many parallel yet singlethreaded
jobs, to also handle multithreaded jobs by adding support for splitting up
the work evenly, specifying a minimum amount of work that's appropriate
for one helper thread to do, load balancing between helpers, and
coordinating them.

This is inspired by work from Pavel Tatashin and Steve Sistare.

From: Daniel Jordan <daniel.m.jordan@oracle.com>
Subject: mm: parallelize deferred_init_memmap()

Deferred struct page init is a significant bottleneck in kernel boot. 
Optimizing it maximizes availability for large-memory systems and allows
spinning up short-lived VMs as needed without having to leave them
running.  It also benefits bare metal machines hosting VMs that are
sensitive to downtime.  In projects such as VMM Fast Restart[1], where
guest state is preserved across kexec reboot, it helps prevent application
and network timeouts in the guests.

Multithread to take full advantage of system memory bandwidth.

The maximum number of threads is capped at the number of CPUs on the node
because speedups always improve with additional threads on every system
tested, and at this phase of boot, the system is otherwise idle and
waiting on page init to finish.

Helper threads operate on section-aligned ranges to both avoid false
sharing when setting the pageblock's migrate type and to avoid accessing
uninitialized buddy pages, though max order alignment is enough for the
latter.

The minimum chunk size is also a section.  There was benefit to using
multiple threads even on relatively small memory (1G) systems, and this is
the smallest size that the alignment allows.

The time (milliseconds) is the slowest node to initialize since boot
blocks until all nodes finish.  intel_pstate is loaded in active mode
without hwp and with turbo enabled, and intel_idle is active as well.

Subject: mm: make deferred init's max threads arch-specific

Using padata during deferred init has only been tested on x86, so for now
limit it to this architecture.

If another arch wants this, it can find the max thread limit that's best
for it and override deferred_page_init_max_threads().

 The padata parallel execution mechanism
 =======================================
 
-:Date: December 2019

 Padata is a mechanism by which the kernel can farm jobs out to be done in
-parallel on multiple CPUs while retaining their ordering.  It was developed for
-use with the IPsec code, which needs to be able to perform encryption and
-decryption on large numbers of packets without reordering those packets.  The
-crypto developers made a point of writing padata in a sufficiently general

-Usage
-=====
+It was originally developed for IPsec, which needs to perform encryption and
+decryption on large numbers of packets without reordering those packets.  This

+Padata also supports multithreaded jobs, splitting up the job evenly while load
+balancing and coordinating between threads.

+Running Multithreaded Jobs
+==========================
+
+A multithreaded job has a main thread and zero or more helper threads, with the
+main thread participating in the job and then waiting until all helpers have
+finished.  padata splits the job into units called chunks, where a chunk is a
+piece of the job that one thread completes in one call to the thread function.

+A user has to do three things to run a multithreaded job.  First, describe the
+job by defining a padata_mt_job structure, which is explained in the Interface
+section.  This includes a pointer to the thread function, which padata will
+call each time it assigns a job chunk to a thread.  Then, define the thread
+function, which accepts three arguments, ``start``, ``end``, and ``arg``, where
+the first two delimit the range that the thread operates on and the last is a
+pointer to the job's shared state, if any.  Prepare the shared state, which is
+typically a stack-allocated structure that wraps the required data.  Last, call
+padata_do_multithreaded(), which will return once the job is finished.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: sparc32: use PUD rather than PGD to get PMD in srmmu_nocache_init()

The kbuild test robot reported the following warning:

arch/sparc/mm/srmmu.c: In function 'srmmu_nocache_init':
>> arch/sparc/mm/srmmu.c:300:9: error: variable 'pud' set but not used
>> [-Werror=unused-but-set-variable]
300 |  pud_t *pud;

This warning is caused by misprint in the page table traversal in
srmmu_nocache_init() function which accessed a PMD entry using PGD rather
than PUD.
Since sparc32 has only 3 page table levels, the PGD and PUD are essentially
the same and usage of __nocache_fix() removed the type checking.

Use PUD for the consistency and to silence the compiler warning.

Subject: z3fold: fix use-after-free when freeing handles

free_handle() for a foreign handle may race with inter-page compaction,
what can lead to memory corruption.  To avoid that, take write lock not
read lock in free_handle to be synchronized with __release_z3fold_page().

For example KASAN can detect it:

Apart from that, initialize zhdr->mapped_count in init_z3fold_page() and
remove "newpage" variable because it is not used anywhere.

Kdump is implemented based on kexec, however some files are only related
to crash dumping and missing, add them to KDUMP entry.

After investigation, it turns out that this is introduced by commit of
linux-next: commit f6edbdb71877 ("mm: memmap_init: iterate over memblock
regions rather that check each PFN").

After investigation, it turns out that this is introduced by commit of
linux-next, the patch subject is:
  "mm: memmap_init: iterate over memblock regions rather that check each PFN".

Qian added debugging code. The debugging log shows that the fault page is
0x2a800000. From the system e820 map which is pasted at bottom, the page
is in e820 reserved range:
	BIOS-e820: [mem 0x0000000029ffe000-0x000000002a80afff] reserved
And it's in section [0x28000000, 0x2fffffff]. In that secion, there are
several usable ranges and some e820 reserved ranges.

For this kind of e820 reserved range, it won't be added to memblock allocator.
However, init_unavailable_mem() will initialize to add them into node 0,
zone 0. Before that commit, later, memmap_init() will add e820 reserved
ranges into the zone where they are contained, because it can pass
the checking of early_pfn_valid() and early_pfn_in_nid(). In this case,
the e820 reserved range where fault page 0x2a800000 is located is added
into DMA32 zone. After that commit, the e820 reserved rgions are kept
in node 0, zone 0, since we iterate over memblock regions to iniatialize
in memmap_init() instead, their node and zone won't be changed.

Now, fast_isolate_freepages() will use min mark directly as the migration
target if no page is found from buddy. However, the min mark is not checked
carefully, it could be in e820 reserved range, and trigger the
VM_BUG_ON_PAGE(!zone_spans_pfn(page_zone(page), pfn)) when try to mark it
as skip.

Here, let's call pageblock_pfn_to_page() to get page of min_pfn, since it
will do careful checks and return NULL if the pfn is not qualified.

------------------------------------------------------
From: Huang Ying <ying.huang@intel.com>
Subject: swap: reduce lock contention on swap cache from swap slots allocation

In some swap scalability test, it is found that there are heavy lock
contention on swap cache even if we have split one swap cache radix tree
per swap device to one swap cache radix tree every 64 MB trunk in commit
4b3ef9daa4fc ("mm/swap: split swap cache into 64MB trunks").

The reason is as follow.  After the swap device becomes fragmented so that
there's no free swap cluster, the swap device will be scanned linearly to
find the free swap slots.  swap_info_struct->cluster_next is the next
scanning base that is shared by all CPUs.  So nearby free swap slots will
be allocated for different CPUs.  The probability for multiple CPUs to
operate on the same 64 MB trunk is high.  This causes the lock contention
on the swap cache.

To solve the issue, in this patch, for SSD swap device, a percpu version
next scanning base (cluster_next_cpu) is added.  Every CPU will use its
own per-cpu next scanning base.  And after finishing scanning a 64MB
trunk, the per-cpu scanning base will be changed to the beginning of
another randomly selected 64MB trunk.  In this way, the probability for
multiple CPUs to operate on the same 64 MB trunk is reduced greatly.  Thus
the lock contention is reduced too.  For HDD, because sequential access is
more important for IO performance, the original shared next scanning base
is used.

To test the patch, we have run 16-process pmbench memory benchmark on a
2-socket server machine with 48 cores.  One ram disk is configured as the
swap device per socket.  The pmbench working-set size is much larger than
the available memory so that swapping is triggered.  The memory read/write
ratio is 80/20 and the accessing pattern is random.  In the original
implementation, the lock contention on the swap cache is heavy.  The perf
profiling data of the lock contention code path is as following,

_raw_spin_lock_irq.add_to_swap_cache.add_to_swap.shrink_page_list:      7.91
_raw_spin_lock_irqsave.__remove_mapping.shrink_page_list:               7.11
_raw_spin_lock.swapcache_free_entries.free_swap_slot.__swap_entry_free: 2.51
_raw_spin_lock_irqsave.swap_cgroup_record.mem_cgroup_uncharge_swap:     1.66
_raw_spin_lock_irq.shrink_inactive_list.shrink_lruvec.shrink_node:      1.29
_raw_spin_lock.free_pcppages_bulk.drain_pages_zone.drain_pages:         1.03
_raw_spin_lock_irq.shrink_active_list.shrink_lruvec.shrink_node:        0.93

After applying this patch, it becomes,

_raw_spin_lock.swapcache_free_entries.free_swap_slot.__swap_entry_free: 3.58
_raw_spin_lock_irq.shrink_inactive_list.shrink_lruvec.shrink_node:      2.3
_raw_spin_lock_irqsave.swap_cgroup_record.mem_cgroup_uncharge_swap:     2.26
_raw_spin_lock_irq.shrink_active_list.shrink_lruvec.shrink_node:        1.8
_raw_spin_lock.free_pcppages_bulk.drain_pages_zone.drain_pages:         1.19

The lock contention on the swap cache is almost eliminated.

And the pmbench score increases 18.5%.  The swapin throughput
increases 18.7% from 2.96 GB/s to 3.51 GB/s.  While the swapout
throughput increases 18.5% from 2.99 GB/s to 3.54 GB/s.

From: Michel Lespinasse <walken@google.com>
Subject: mmap locking API: initial implementation as rwsem wrappers

This patch series adds a new mmap locking API replacing the existing
mmap_sem lock and unlocks.  Initially the API is just implemente in terms
of inlined rwsem calls, so it doesn't provide any new functionality.

There are two justifications for the new API:

- At first, it provides an easy hooking point to instrument mmap_sem
  locking latencies independently of any other rwsems.

- In the future, it may be a starting point for replacing the rwsem
  implementation with a different one, such as range locks.  This is
  something that is being explored, even though there is no wide concensus
  about this possible direction yet.  (see
  https://patchwork.kernel.org/cover/11401483/)


This patch (of 12):

This change wraps the existing mmap_sem related rwsem calls into a new
mmap locking API.  There are two justifications for the new API:

- At first, it provides an easy hooking point to instrument mmap_sem
  locking latencies independently of any other rwsems.

- In the future, it may be a starting point for replacing the rwsem
  implementation with a different one, such as range locks.

Subject: mmap locking API: convert mmap_sem call sites missed by coccinelle

Convert the last few remaining mmap_sem rwsem calls to use the new mmap
locking API.  These were missed by coccinelle for some reason (I think
coccinelle does not support some of the preprocessor constructs in these
files ?)

From: Michel Lespinasse <walken@google.com>
Subject: mmap locking API: add mmap_read_trylock_non_owner()

Add a couple APIs used by kernel/bpf/stackmap.c only:
- mmap_read_trylock_non_owner()
- mmap_read_unlock_non_owner() (may be called from a work queue).

It's still not ideal that bpf/stackmap subverts the lock ownership in this
way.  Thanks to Peter Zijlstra for suggesting this API as the least-ugly
way of addressing this in the short term.

rwsem.

Subject: mmap locking API: add mmap_assert_locked() and mmap_assert_write_locked()

Add new APIs to assert that mmap_sem is held.

Using this instead of rwsem_is_locked and lockdep_assert_held[_write]
makes the assertions more tolerant of future changes to the lock type.

From: Michel Lespinasse <walken@google.com>
Subject: mmap locking API: rename mmap_sem to mmap_lock

Rename the mmap_sem field to mmap_lock.  Any new uses of this lock should
now go through the new mmap locking api.  The mmap_lock is still
implemented as a rwsem, though this could change in the future.

Subject: mm: fix LRU balancing effect of new transparent huge pages

The reclaim code that balances between swapping and cache reclaim tries to
predict likely reuse based on in-memory reference patterns alone.  This
works in many cases, but when it fails it cannot detect when the cache is
thrashing pathologically, or when we're in the middle of a swap storm.

The high seek cost of rotational drives under which the algorithm evolved
also meant that mistakes could quickly result in lockups from too
aggressive swapping (which is predominantly random IO).  As a result, the
balancing code has been tuned over time to a point where it mostly goes
for page cache and defers swapping until the VM is under significant
memory pressure.

The resulting strategy doesn't make optimal caching decisions - where
optimal is the least amount of IO required to execute the workload.

The proliferation of fast random IO devices such as SSDs, in-memory
compression such as zswap, and persistent memory technologies on the
horizon, has made this undesirable behavior very noticable: Even in the
presence of large amounts of cold anonymous memory and a capable swap
device, the VM refuses to even seriously scan these pages, and can leave
the page cache thrashing needlessly.

This series sets out to address this.  Since commit ("a528910e12ec mm:
thrash detection-based file cache sizing") we have exact tracking of
refault IO - the ultimate cost of reclaiming the wrong pages.  This allows
us to use an IO cost based balancing model that is more aggressive about
scanning anonymous memory when the cache is thrashing, while being able to
avoid unnecessary swap storms.

These patches base the LRU balance on the rate of refaults on each list,
times the relative IO cost between swap device and filesystem
(swappiness), in order to optimize reclaim for least IO cost incurred.

	History

I floated these changes in 2016.  At the time they were incomplete and
full of workarounds due to a lack of infrastructure in the reclaim code:
We didn't have PageWorkingset, we didn't have hierarchical cgroup
statistics, and problems with the cgroup swap controller.  As swapping
wasn't too high a priority then, the patches stalled out.  With all
dependencies in place now, here we are again with much cleaner,
feature-complete patches.

I kept the acks for patches that stayed materially the same :-)

Below is a series of test results that demonstrate certain problematic
behavior of the current code, as well as showcase the new code's more
predictable and appropriate balancing decisions.

	Test #1: No convergence

This test shows an edge case where the VM currently doesn't converge at
all on a new file workingset with a stale anon/tmpfs set.

The test sets up a cold anon set the size of 3/4 RAM, then tries to
establish a new file set half the size of RAM (flat access pattern).

The vanilla kernel refuses to even scan anon pages and never converges. 
The file set is perpetually served from the filesystem.

The first test kernel is with the series up to the workingset patch
applied.  This allows thrashing page cache to challenge the anonymous
workingset.  The VM then scans the lists based on the current
scanned/rotated balancing algorithm.  It converges on a stable state where
all cold anon pages are pushed out and the fileset is served entirely from
cache:

			    noconverge/5.7-rc5-mm	noconverge/5.7-rc5-mm-workingset
Scanned			417719308.00 (    +0.00%)		64091155.00 (   -84.66%)
Reclaimed		417711094.00 (    +0.00%)		61640308.00 (   -85.24%)
Reclaim efficiency %	      100.00 (    +0.00%)		      96.18 (    -3.78%)
Scanned file		417719308.00 (    +0.00%)		59211118.00 (   -85.83%)
Scanned anon			0.00 (    +0.00%)	         4880037.00 (          )
Swapouts			0.00 (    +0.00%)	         2439957.00 (          )
Swapins				0.00 (    +0.00%)		     257.00 (          )
Refaults		415246605.00 (    +0.00%)		59183722.00 (   -85.75%)
Restore refaults		0.00 (    +0.00%)	        54988252.00 (          )

The second test kernel is with the full patch series applied, which
replaces the scanned/rotated ratios with refault/swapin rate-based
balancing.  It evicts the cold anon pages more aggressively in the
presence of a thrashing cache and the absence of swapins, and so converges
with about 60% of the IO and reclaim activity:

			noconverge/5.7-rc5-mm-workingset	noconverge/5.7-rc5-mm-lrubalance
Scanned				64091155.00 (    +0.00%)		37579741.00 (   -41.37%)
Reclaimed			61640308.00 (    +0.00%)		35129293.00 (   -43.01%)
Reclaim efficiency %		      96.18 (    +0.00%)		      93.48 (    -2.78%)
Scanned file			59211118.00 (    +0.00%)		32708385.00 (   -44.76%)
Scanned anon			 4880037.00 (    +0.00%)		 4871356.00 (    -0.18%)
Swapouts			 2439957.00 (    +0.00%)		 2435565.00 (    -0.18%)
Swapins				     257.00 (    +0.00%)		     262.00 (    +1.94%)
Refaults			59183722.00 (    +0.00%)		32675667.00 (   -44.79%)
Restore refaults		54988252.00 (    +0.00%)		28480430.00 (   -48.21%)

We're triggering this case in host sideloading scenarios: When a host's
primary workload is not saturating the machine (primary load is usually
driven by user activity), we can optimistically sideload a batch job; if
user activity picks up and the primary workload needs the whole host
during this time, we freeze the sideload and rely on it getting pushed to
swap.  Frequently that swapping doesn't happen and the completely inactive
sideload simply stays resident while the expanding primary worklad is
struggling to gain ground.

	Test #2: Kernel build

This test is a a kernel build that is slightly memory-restricted (make -j4
inside a 400M cgroup).

Despite the very aggressive swapping of cold anon pages in test #1, this
test shows that the new kernel carefully balances swap against cache
refaults when both the file and the cache set are pressured.

It shows the patched kernel to be slightly better at finding the coldest
memory from the combined anon and file set to evict under pressure.  The
result is lower aggregate reclaim and paging activity:

z				    5.7-rc5-mm	5.7-rc5-mm-lrubalance
Real time		   210.60 (    +0.00%)	   210.97 (    +0.18%)
User time		   745.42 (    +0.00%)	   746.48 (    +0.14%)
System time		    69.78 (    +0.00%)	    69.79 (    +0.02%)

Scanned anon		465381.00 (    +0.00%)	378144.00 (   -18.75%)
Swapouts		185920.00 (    +0.00%)	147801.00 (   -20.50%)
Swapins			 34583.00 (    +0.00%)	 32491.00 (    -6.05%)
Refaults		212664.00 (    +0.00%)	172409.00 (   -18.93%)
Restore refaults	 48861.00 (    +0.00%)	 80091.00 (   +63.91%)
Total paging IO		433167.00 (    +0.00%)	352701.00 (   -18.58%)

	Test #3: Overload

This next test is not about performance, but rather about the
predictability of the algorithm.  The current balancing behavior doesn't
always lead to comprehensible results, which makes performance analysis
and parameter tuning (swappiness e.g.) very difficult.

The test shows the balancing behavior under equivalent anon and file
input.  Anon and file sets are created of equal size (3/4 RAM), have the
same access patterns (a hot-cold gradient), and synchronized access rates.
Swappiness is raised from the default of 60 to 100 to indicate equal IO
cost between swap and cache.

With the vanilla balancing code, anon scans make up around 9% of the total
pages scanned, or a ~1:10 ratio.  This is a surprisingly skewed ratio, and
it's an outcome that is hard to explain given the input parameters to the
VM.

The new balancing model targets a 1:2 balance: All else being equal,
reclaiming a file page costs one page IO - the refault; reclaiming an anon
page costs two IOs - the swapout and the swapin.  In the test we observe a
~1:3 balance.

The scanned and paging IO numbers indicate that the anon LRU algorithm we
have in place right now does a slightly worse job at picking the coldest
pages compared to the file algorithm.  There is ongoing work to improve
this, like Joonsoo's anon workingset patches; however, it's difficult to
compare the two aging strategies when the balancing between them is
behaving unintuitively.

The slightly less efficient anon reclaim results in a deviation from the
optimal 1:2 scan ratio we would like to see here - however, 1:3 is much
closer to what we'd want to see in this test than the vanilla kernel's
aging of 10+ cache pages for every anonymous one:

			overload-100/5.7-rc5-mm-workingset	overload-100/5.7-rc5-mm-lrubalance-realfile

Total paging IO			 497943780.00 (    +0.00%)			  562616669.00 (   +12.99%)

	Test #4: Parallel IO

It's important to note that these patches only affect the situation where
the kernel has to reclaim workingset memory, which is usually a
transitionary period.  The vast majority of page reclaim occuring in a
system is from trimming the ever-expanding page cache.

These patches don't affect cache trimming behavior.  We never swap as long
as we only have use-once cache moving through the file LRU, we only
consider swapping when the cache is actively thrashing.

The following test demonstrates this.  It has an anon workingset that
takes up half of RAM and then writes a file that is twice the size of RAM
out to disk.

As the cache is funneled through the inactive file list, no anon pages are
scanned (aside from apparently some background noise of 10 pages):

					  5.7-rc5-mm		          5.7-rc5-mm-lrubalance
Scanned			    10714722.00 (    +0.00%)		       10723445.00 (    +0.08%)
Reclaimed		    10703596.00 (    +0.00%)		       10712166.00 (    +0.08%)
Reclaim efficiency %		  99.90 (    +0.00%)			     99.89 (    -0.00%)
Scanned file		    10714722.00 (    +0.00%)		       10723435.00 (    +0.08%)
Scanned anon			   0.00 (    +0.00%)			     10.00 (          )
Swapouts			   0.00 (    +0.00%)			      7.00 (          )
Swapins				   0.00 (    +0.00%)			      0.00 (    +0.00%)
Refaults			  92.00 (    +0.00%)			     41.00 (   -54.84%)
Restore refaults		   0.00 (    +0.00%)			      0.00 (    +0.00%)
Total paging IO			  92.00 (    +0.00%)			     48.00 (   -47.31%)


This patch (of 14):

Currently, THP are counted as single pages until they are split right
before being swapped out.  However, at that point the VM is already in the
middle of reclaim, and adjusting the LRU balance then is useless.

Always account THP by the number of basepages, and remove the fixup from
the splitting path.

Subject: mm: keep separate anon and file statistics on page reclaim activity

Having statistics on pages scanned and pages reclaimed for both anon and
file pages makes it easier to evaluate changes to LRU balancing.

While at it, clean up the stat-keeping mess for isolation, putback,
reclaim stats etc.  a bit: first the physical LRU operation (isolation and
putback), followed by vmstats, reclaim_stats, and then vm events.

Subject: mm: allow swappiness that prefers reclaiming anon over the file workingset

With the advent of fast random IO devices (SSDs, PMEM) and in-memory swap
devices such as zswap, it's possible for swap to be much faster than
filesystems, and for swapping to be preferable over thrashing filesystem
caches.

Allow setting swappiness - which defines the rough relative IO cost of
cache misses between page cache and swap-backed pages - to reflect such
situations by making the swap-preferred range configurable.

-This control is used to define how aggressive the kernel will swap
-memory pages.  Higher values will increase aggressiveness, lower values
-decrease the amount of swap.  A value of 0 instructs the kernel not to
-initiate swap until the amount of free and file-backed pages is less
-than the high water mark in a zone.
+This control is used to define the rough relative IO cost of swapping
+and filesystem paging, as a value between 0 and 200. At 100, the VM
+assumes equal IO cost and will thus apply memory pressure to the page
+cache and swap-backed pages equally; lower values signify more
+expensive swap IO, higher values indicates cheaper.
+
+Keep in mind that filesystem IO patterns under memory pressure tend to
+be more efficient than swap's random IO. An optimal value will require
+experimentation and will also be workload-dependent.
 
 The default value is 60.
 
+For in-memory swap, like zram or zswap, as well as hybrid setups that
+have swap on faster devices than the filesystem, values beyond 100 can
+be considered. For example, if the random IO against the swap device
+is on average 2x faster than IO from the filesystem, swappiness should
+be 133 (x + 2x = 200, 2x = 133.33).
+
+At 0, the kernel will not initiate swap until the amount of free and
+file-backed pages is less than the high watermark in a zone.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: workingset: let cache workingset challenge anon

We activate cache refaults with reuse distances in pages smaller than the
size of the total cache.  This allows new pages with competitive access
frequencies to establish themselves, as well as challenge and potentially
displace pages on the active list that have gone cold.

However, that assumes that active cache can only replace other active
cache in a competition for the hottest memory.  This is not a great
default assumption.  The page cache might be thrashing while there are
enough completely cold and unused anonymous pages sitting around that we'd
only have to write to swap once to stop all IO from the cache.

Activate cache refaults when their reuse distance in pages is smaller than
the total userspace workingset, including anonymous pages.

Reclaim can still decide how to balance pressure among the two LRUs
depending on the IO situation.  Rotational drives will prefer avoiding
random IO from swap and go harder after cache.  But fundamentally, hot
cache should be able to compete with anon pages for a place in RAM.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: remove use-once cache bias from LRU balancing

When the splitlru patches divided page cache and swap-backed pages into
separate LRU lists, the pressure balance between the lists was biased to
account for the fact that streaming IO can cause memory pressure with a
flood of pages that are used only once.  New page cache additions would
tip the balance toward the file LRU, and repeat access would neutralize
that bias again.  This ensured that page reclaim would always go for
used-once cache first.

Since e9868505987a ("mm,vmscan: only evict file pages when we have
plenty"), page reclaim generally skips over swap-backed memory entirely as
long as there is used-once cache present, and will apply the LRU balancing
when only repeatedly accessed cache pages are left - at which point the
previous use-once bias will have been neutralized.  This makes the
use-once cache balancing bias unnecessary.

Subject: mm: vmscan: drop unnecessary div0 avoidance rounding in get_scan_count()

When we calculate the relative scan pressure between the anon and file LRU
lists, we have to assume that reclaim_stat can contain zeroes.  To avoid
div0 crashes, we add 1 to all denominators like so:

        anon_prio = swappiness;
        file_prio = 200 - anon_prio;

	[...]

        /*
         * The amount of pressure on anon vs file pages is inversely
         * proportional to the fraction of recently scanned pages on
         * each list that were recently referenced and in active use.
         */
        ap = anon_prio * (reclaim_stat->recent_scanned[0] + 1);
        ap /= reclaim_stat->recent_rotated[0] + 1;

        fp = file_prio * (reclaim_stat->recent_scanned[1] + 1);
        fp /= reclaim_stat->recent_rotated[1] + 1;
        spin_unlock_irq(&pgdat->lru_lock);

        fraction[0] = ap;
        fraction[1] = fp;
        denominator = ap + fp + 1;

While reclaim_stat can contain 0, it's not actually possible for ap + fp
to be 0.  One of anon_prio or file_prio could be zero, but they must still
add up to 200.  And the reclaim_stat fraction, due to the +1 in there, is
always at least 1.  So if one of the two numerators is 0, the other one
can't be.  ap + fp is always at least 1.  Drop the + 1.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: base LRU balancing on an explicit cost model

Currently, scan pressure between the anon and file LRU lists is balanced
based on a mixture of reclaim efficiency and a somewhat vague notion of
"value" of having certain pages in memory over others.  That concept of
value is problematic, because it has caused us to count any event that
remotely makes one LRU list more or less preferrable for reclaim, even
when these events are not directly comparable and impose very different
costs on the system.  One example is referenced file pages that we still
deactivate and referenced anonymous pages that we actually rotate back to
the head of the list.

There is also conceptual overlap with the LRU algorithm itself.  By
rotating recently used pages instead of reclaiming them, the algorithm
already biases the applied scan pressure based on page value.  Thus, when
rebalancing scan pressure due to rotations, we should think of reclaim
cost, and leave assessing the page value to the LRU algorithm.

Lastly, considering both value-increasing as well as value-decreasing
events can sometimes cause the same type of event to be counted twice,
i.e.  how rotating a page increases the LRU value, while reclaiming it
succesfully decreases the value.  In itself this will balance out fine,
but it quietly skews the impact of events that are only recorded once.

The abstract metric of "value", the murky relationship with the LRU
algorithm, and accounting both negative and positive events make the
current pressure balancing model hard to reason about and modify.

This patch switches to a balancing model of accounting the concrete,
actually observed cost of reclaiming one LRU over another.  For now, that
cost includes pages that are scanned but rotated back to the list head. 
Subsequent patches will add consideration for IO caused by refaulting of
recently evicted pages.

Replace struct zone_reclaim_stat with two cost counters in the lruvec, and
make everything that affects cost go through a new lru_note_cost()
function.

Operations like MADV_FREE, FADV_DONTNEED etc.  currently move any affected
active pages to the inactive list to accelerate their reclaim (good) but
also steer page reclaim toward that LRU type, or away from the other
(bad).

The reason why this is undesirable is that such operations are not part of
the regular page aging cycle, and rather a fluke that doesn't say much
about the remaining pages on that list; they might all be in heavy use,
and once the chunk of easy victims has been purged, the VM continues to
apply elevated pressure on those remaining hot pages.  The other LRU,
meanwhile, might have easily reclaimable pages, and there was never a need
to steer away from it in the first place.

As the previous patch outlined, we should focus on recording actually
observed cost to steer the balance rather than speculating about the
potential value of one LRU list over the other.  In that spirit, leave
explicitely deactivated pages to the LRU algorithm to pick up, and let
rotations decide which list is the easiest to reclaim.

Subject: mm: only count actual rotations as LRU reclaim cost

When shrinking the active file list we rotate referenced pages only when
they're in an executable mapping.  The others get deactivated.  When it
comes to balancing scan pressure, though, we count all referenced pages as
rotated, even the deactivated ones.  Yet they do not carry the same cost
to the system: the deactivated page *might* refault later on, but the
deactivation is tangible progress toward freeing pages; rotations on the
other hand cost time and effort without getting any closer to freeing
memory.

Don't treat both events as equal.  The following patch will hook up LRU
balancing to cache and anon refaults, which are a much more concrete cost
signal for reclaiming one list over the other.  Thus, remove the maybe-IO
cost bias from page references, and only note the CPU cost for actual
rotations that prevent the pages from getting reclaimed.

Subject: mm: balance LRU lists based on relative thrashing

Since the LRUs were split into anon and file lists, the VM has been
balancing between page cache and anonymous pages based on per-list ratios
of scanned vs.  rotated pages.  In most cases that tips page reclaim
towards the list that is easier to reclaim and has the fewest actively
used pages, but there are a few problems with it:

1. Refaults and LRU rotations are weighted the same way, even though
   one costs IO and the other costs a bit of CPU.

2. The less we scan an LRU list based on already observed rotations,
   the more we increase the sampling interval for new references, and
   rotations become even more likely on that list. This can enter a
   death spiral in which we stop looking at one list completely until
   the other one is all but annihilated by page reclaim.

Since commit a528910e12ec ("mm: thrash detection-based file cache sizing")
we have refault detection for the page cache.  Along with swapin events,
they are good indicators of when the file or anon list, respectively, is
too small for its workingset and needs to grow.

For example, if the page cache is thrashing, the cache pages need more
time in memory, while there may be colder pages on the anonymous list. 
Likewise, if swapped pages are faulting back in, it indicates that we
reclaim anonymous pages too aggressively and should back off.

Replace LRU rotations with refaults and swapins as the basis for relative
reclaim cost of the two LRUs.  This will have the VM target list balances
that incur the least amount of IO on aggregate.

Subject: mm: vmscan: determine anon/file pressure balance at the reclaim root

We split the LRU lists into anon and file, and we rebalance the scan
pressure between them when one of them begins thrashing: if the file cache
experiences workingset refaults, we increase the pressure on anonymous
pages; if the workload is stalled on swapins, we increase the pressure on
the file cache instead.

With cgroups and their nested LRU lists, we currently don't do this
correctly.  While recursive cgroup reclaim establishes a relative LRU
order among the pages of all involved cgroups, LRU pressure balancing is
done on an individual cgroup LRU level.  As a result, when one cgroup is
thrashing on the filesystem cache while a sibling may have cold anonymous
pages, pressure doesn't get equalized between them.

This patch moves LRU balancing decision to the root of reclaim - the same
level where the LRU order is established.

It does this by tracking LRU cost recursively, so that every level of the
cgroup tree knows the aggregate LRU cost of all memory within its domain. 
When the page scanner calculates the scan balance for any given individual
cgroup's LRU list, it uses the values from the ancestor cgroup that
initiated the reclaim cycle.

If one sibling is then thrashing on the cache, it will tip the pressure
balance inside its ancestors, and the next hierarchical reclaim iteration
will go more after the anon pages in the tree.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: vmscan: reclaim writepage is IO cost

The VM tries to balance reclaim pressure between anon and file so as to
reduce the amount of IO incurred due to the memory shortage.  It already
counts refaults and swapins, but in addition it should also count
writepage calls during reclaim.

For swap, this is obvious: it's IO that wouldn't have occurred if the
anonymous memory hadn't been under memory pressure.  From a relative
balancing point of view this makes sense as well: even if anon is cold and
reclaimable, a cache that isn't thrashing may have equally cold pages that
don't require IO to reclaim.

For file writeback, it's trickier: some of the reclaim writepage IO would
have likely occurred anyway due to dirty expiration.  But not all of it -
premature writeback reduces batching and generates additional writes. 
Since the flushers are already woken up by the time the VM starts writing
cache pages one by one, let's assume that we'e likely causing writes that
wouldn't have happened without memory pressure.  In addition, the per-page
cost of IO would have probably been much cheaper if written in larger
batches from the flusher thread rather than the single-page-writes from
kswapd.

For our purposes - getting the trend right to accelerate convergence on a
stable state that doesn't require paging at all - this is sufficiently
accurate.  If we later wanted to optimize for sustained thrashing, we can
still refine the measurements.

Count all writepage calls from kswapd as IO cost toward the LRU that the
page belongs to.

Why do this dynamically?  Don't we know in advance that anon pages require
IO to reclaim, and so could build in a static bias?

First, scanning is not the same as reclaiming.  If all the anon pages are
referenced, we may not swap for a while just because we're scanning the
anon list.  During this time, however, it's important that we age
anonymous memory and the page cache at the same rate so that their
hot-cold gradients are comparable.  Everything else being equal, we still
want to reclaim the coldest memory overall.

Second, we keep copies in swap unless the page changes.  If there is
swap-backed data that's mostly read (tmpfs file) and has been swapped out
before, we can reclaim it without incurring additional IO.

Subject: mm: vmscan: limit the range of LRU type balancing

When LRU cost only shows up on one list, we abruptly stop scanning that
list altogether.  That's an extreme reaction: by the time the other list
starts thrashing and the pendulum swings back, we may have no recent age
information on the first list anymore, and we could have significant
latencies until the scanner has caught up.

Soften this change in the feedback system by ensuring that no list
receives less than a third of overall pressure, and only distribute the
other 66% according to LRU cost.  This ensures that we maintain a minimum
rate of aging on the entire workingset while it's being pressured, while
still allowing a generous rate of convergence when the relative sizes of
the lists need to adjust.

[failures] makefile-support-compressed-debug-info.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: Makefile: support compressed debug info
has been removed from the -mm tree.  Its filename was
     makefile-support-compressed-debug-info.patch

This patch was dropped because it had testing failures

------------------------------------------------------
From: Nick Desaulniers <ndesaulniers@google.com>
Subject: Makefile: support compressed debug info

As debug information gets larger and larger, it helps significantly save
the size of vmlinux images to compress the information in the debug
information sections.  Note: this debug info is typically split off from
the final compressed kernel image, which is why vmlinux is what's used in
conjunction with GDB.  Minimizing the debug info size should have no
impact on boot times, or final compressed kernel image size.

All of the debug sections will have a `C` flag set.

As 'GTAGS Manual' said: If ´gtags.files´ exists in the current directory
directory or a file is specified by the -f option, target files are
limited by it.

So add gtags.files just like cscope.files.

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).

do_memsw_account() used to be automatically false when the cgroup
controller was disabled.  Now that it's replaced by cgroup_memory_noswap,
for which this isn't true, make the mem_cgroup_disabled() checks explicit
in the swap control API.

My tree changes a lot :( 658 patches so far this cycle, tons on them in
MM.

linux-next is probably the best way to get at it when it's in a
reasonable shape.  Perhaps you could keep an eye on linux-next, do the
occasional grep send me any fixups for anything which I missed?

It's completely stuck - I'm awaiting some sort of resolution.

It seems that the bug is real - is there any alternative solution on
offer?

mmotm 2020-05-21-20-42 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-21-20-42 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: mm/z3fold: silence kmemleak false positives of slots

Kmemleak reported many leaks while under memory pressue in,

slots = alloc_slots(pool, gfp);

which is referenced by "zhdr" in init_z3fold_page(),

zhdr->slots = slots;

However, "zhdr" could be gone without freeing slots as the later will be
freed separately when the last "handle" off of "handles" array is freed. It
will be within "slots" which is always aligned.

From: Chris Down <chris@chrisdown.name>
Subject: init: allow distribution configuration of default init

Some init systems (eg.  systemd) have init at their own paths, for
example, /usr/lib/systemd/systemd.  A compatibility symlink to one of the
hardcoded init paths is provided by another package, usually named
something like systemd-sysvcompat or similar.

Currently distro maintainers who are hands-off on the bootloader are more
or less required to include those compatibility links as part of their
base distribution, because it's hard to migrate away from them since
there's a risk some users will not get the message to set init= on the
kernel command line appropriately.

Moreover, for distributions where the init system is something the
distribution itself is opinionated about (eg.  Arch, which has systemd in
the required `base` package), we could usually reasonably configure this
ahead of time when building the distribution kernel.  However, we
currently simply don't have any way to configure the kernel to do this. 
Here's an example discussion where removing sysvcompat was discussed by
distro maintainers[0].

This patch adds a new Kconfig tunable, CONFIG_DEFAULT_INIT, which if set
is tried before the hardcoded fallback list.  So the order of precedence
is now thus:

1. init= on command line (on failure: panic)
2. CONFIG_DEFAULT_INIT (on failure: try #3)
3. Hardcoded fallback list (on failure: panic)

This new config parameter will allow distribution maintainers to move away
from these compatibility links safely, without having to worry that their
users might not have the right init=.

There are also two other benefits of this over having the distribution
maintain a symlink:

1. One of the value propositions over simply having distributions
   maintain a /sbin/init symlink via a package is that it also frees
   distributions which have a preferred default, but not mandatory, init
   system from having their package manager fight with their users for
   control of /{s,}bin/init.  Instead, the distribution simply makes
   their preference known in CONFIG_DEFAULT_INIT, and if the user
   installs another init system and uninstalls the default one they can
   still make use of /{s,}bin/init and friends for their own uses. This
   makes more cases Just Work(tm) without the user having to perform
   extra configuration via init=.

2. Since before this we don't know which path the distribution actually
   _intends_ to serve init from, we don't pr_err if it is simply
   missing, and usually will just silently put the user in a /bin/sh
   shell. Now that the distribution can make a declaration of intent, we
   can be more vocal when this init system fails to launch for any
   reason, even if it's simply because no file exists at that location,
   speeding up the palaver of init/mount dependency/etc debugging a bit.

From: Yafang Shao <laoar.shao@gmail.com>
Subject: mm, memcg: avoid stale protection values when cgroup is above protection

Patch series "mm: memcontrol: memory.{low,min} reclaim fix & cleanup", v3.

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 3):

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.

[to-be-updated] mm-memcg-decouple-elowmin-state-mutations-from-protection-checks.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: mm, memcg: decouple e{low,min} state mutations from protection checks
has been removed from the -mm tree.  Its filename was
     mm-memcg-decouple-elowmin-state-mutations-from-protection-checks.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
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.

From: Randy Dunlap <rdunlap@infradead.org>
Subject: mm: swapfile: fix /proc/swaps heading and Size/Used/Priority alignment

Fix the heading and Size/Used/Priority field alignments in /proc/swaps. 
If the Size and/or Used value is >= 10000000 (8 bytes), then the alignment
by using tab characters is broken.

This patch maintains the use of tabs for alignment.  If spaces are
preferred, we can just use a Field Width specifier for the bytes and inuse
fields.  That way those fields don't have to be a multiple of 8 bytes in
width.  E.g., with a field width of 12, both Size and Used would always
fit on the first line of an 80-column wide terminal (only Priority would
be on the second line).

There are actually 2 problems: heading alignment and field width.  On an
xterm, if Used is 7 bytes in length, the tab does nothing, and the display
is like this, with no space/tab between the Used and Priority fields. 
(ugh)

Filename				Type		Size	Used	Priority
/dev/sda8                               partition	16779260	2023012-1

To be clear, if one does 'cat /proc/swaps >/tmp/proc.swaps', it does look
different, like so:

Filename				Type		Size	Used	Priority
/dev/sda8                               partition	16779260	2086988	-1

------------------------------------------------------
From: Hugh Dickins <hughd@google.com>
Subject: mm/swap: fix livelock in __read_swap_cache_async()

I've only seen this livelock on one machine (repeatably, but not to
order), and not fully analyzed it - two processes seen looping around
getting -EEXIST from swapcache_prepare(), I guess a third (at lower
priority?  but wanting the same cpu as one of the loopers?  preemption or
cond_resched() not enough to let it back in?) set SWAP_HAS_CACHE, then
went off into direct reclaim, scheduled away, and somehow could not get
back to add the page to swap cache and let them all complete.

Restore the page allocation in __read_swap_cache_async() to before the
swapcache_prepare() call: "mm: memcontrol: charge swapin pages on
instantiation" moved it outside the loop, which indeed looks much nicer,
but exposed this weakness.  We used to allocate new_page once and then
keep it across all iterations of the loop: but I think that just optimizes
for a rare case, and complicates the flow, so go with the new simpler
structure, with allocate+free each time around (which is more considerate
use of the memory too).

Fix the comment on the looping case, which has long been inaccurate: it's
not a racing get_swap_page() that's the problem here.

Fix the add_to_swap_cache() and mem_cgroup_charge() error recovery: not
swap_free(), but put_swap_page() to undo SWAP_HAS_CACHE, as was done
before; but delete_from_swap_cache() already includes it.

And one more nit: I don't think it makes any difference in practice, but
remove the "& GFP_KERNEL" mask from the mem_cgroup_charge() call:
add_to_swap_cache() needs that, to convert gfp_mask from user and page
cache allocation (e.g.  highmem) to radix node allocation (lowmem), but we

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/gup: might_lock_read(mmap_sem) in get_user_pages_fast()

Instead of scattering these assertions across the drivers, do this
assertion inside the core of get_user_pages_fast*() functions.  That also
includes pin_user_pages_fast*() routines.

Add a might_lock_read(mmap_sem) call to internal_get_user_pages_fast().

do_memsw_account() used to be automatically false when the cgroup
controller was disabled.  Now that it's replaced by cgroup_memory_noswap,
for which this isn't true, make the mem_cgroup_disabled() checks explicit
in the swap control API.

Swap accounting used to be implied-disabled when the cgroup controller was
disabled.  Restore that for the new cgroup_memory_noswap, so that we bail
out of this function instead of dereferencing a NULL memcg.

mmotm 2020-05-22-20-35 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-22-20-35 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-memcg-decouple-elowmin-state-mutations-from-protection-checks.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm, memcg: decouple e{low,min} state mutations from protection checks
has been removed from the -mm tree.  Its filename was
     mm-memcg-decouple-elowmin-state-mutations-from-protection-checks.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
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.
