Subject: ia64: fix #endif comment for reserve_elfcorehdr()
Patch series "ia64: Miscellaneous fixes and cleanups".
This patch series contains some miscellaneous fixes and cleanups for ia64.
The second patch fixes a naming conflict triggered by a patch for the FDT
code.
This patch (of 3):
The definition of reserve_elfcorehdr() depends on CONFIG_CRASH_DUMP, not
CONFIG_PROC_VMCORE.

Fixes: d9a9855d0b06ca6d ("always reserve elfcore header memory in crash kernel")

There never was a reason for reserve_elfcorehdr() to be global. Make the
function static, and move it before its sole caller.

The case where "tmp_oh" is NULL is handled at the start of the function.
At this point we know it's non-NULL so this will always return 1.

Subject: ocfs2: quota_local: fix possible uninitialized-variable access in ocfs2_local_read_info()
A memory block is allocated through kmalloc(), and its return value is
assigned to the pointer oinfo. However, oinfo->dqi_gqinode is not
initialized but it is accessed in:
iput(oinfo->dqi_gqinode);
To fix this possible uninitialized-variable access, assign NULL to
oinfo->dqi_gqinode, and add ocfs2_qinfo_lock_res_init() behind the
assignment in ocfs2_local_read_info(). Remove ocfs2_qinfo_lock_res_init()
in ocfs2_global_read_info().

Subject: ocfs2: ocfs2_downconvert_lock failure results in deadlock
Usually, ocfs2_downconvert_lock() function always downconverts dlm lock to
the expected level for satisfy dlm bast requests from the other nodes.
But there is a rare situation. When dlm lock conversion is being
canceled, ocfs2_downconvert_lock() function will return -EBUSY. You need
to be aware that ocfs2_cancel_convert() function is asynchronous in fsdlm
implementation.
If we does not requeue this lockres entry, ocfs2 downconvert thread no
longer handles this dlm lock bast request. Then, the other nodes will not
get the dlm lock again, the current node's process will be blocked when
acquire this dlm lock again.

Subject: mm, slub: don't call flush_all() from slab_debug_trace_open()
Patch series "SLUB: reduce irq disabled scope and make it RT compatible", v4.
This series was initially inspired by Mel's pcplist local_lock rewrite,
and also interest to better understand SLUB's locking and the new
primitives and RT variants and implications. It should make SLUB more
preemption-friendly, especially for RT, hopefully without noticeable
regressions, as the fast paths are not affected.
The RFC/v1 version got basic performance screening by Mel that didn't show
major regressions. Mike's testing with hackbench of v2 on !RT reported
negligible differences [6]:

RT configs showed some throughput regressions, but that's expected
tradeoff for the preemption improvements through the RT mutex. It didn't
prevent the v2 to be incorporated to the 5.13 RT tree [7], leading to
testing exposure and bugfixes.
Before the series, SLUB is lockless in both allocation and free fast
paths, but elsewhere, it's disabling irqs for considerable periods of time
- especially in allocation slowpath and the bulk allocation, where IRQs
are re-enabled only when a new page from the page allocator is needed, and
the context allows blocking. The irq disabled sections can then include
deactivate_slab() which walks a full freelist and frees the slab back to
page allocator or unfreeze_partials() going through a list of percpu
partial slabs. The RT tree currently has some patches mitigating these,
but we can do much better in mainline too.
Patches 1-6 are straightforward improvements or cleanups that could exist
outside of this series too, but are prerequsities.
Patches 7-10 are also preparatory code changes without functional changes,
but not so useful without the rest of the series.
Patch 11 simplifies the fast paths on systems with preemption, based on
(hopefully correct) observation that the current loops to verify tid are
unnecessary.
Patches 12-21 focus on reducing irq disabled scope in the allocation
slowpath.
Patch 12 moves disabling of irqs into ___slab_alloc() from its callers,
which are the allocation slowpath, and bulk allocation. Instead these
callers only disable preemption to stabilize the cpu. The following
patches then gradually reduce the scope of disabled irqs in
___slab_alloc() and the functions called from there. As of patch 15, the
re-enabling of irqs based on gfp flags before calling the page allocator
is removed from allocate_slab(). As of patch 18, it's possible to reach
the page allocator (in case of existing slabs depleted) without disabling
and re-enabling irqs a single time.
Pathces 22-27 reduce the scope of disabled irqs in functions related to
unfreezing percpu partial slab.
Patch 28 is preparatory. Patch 29 is adopted from the RT tree and
converts the flushing of percpu slabs on all cpus from using IPI to
workqueue, so that the processing isn't happening with irqs disabled in
the IPI handler. The flushing is not performance critical so it should be
acceptable.
Patch 30 also comes from RT tree and makes object_map_lock RT compatible.
Patches 31-32 make slab_lock irq-safe on RT where we cannot rely on having
irq disabled from the list_lock spin lock usage.
Patch 33 changes kmem_cache_cpu->partial handling in put_cpu_partial()
from cmpxchg loop to a short irq disabled section, which is used by all
other code modifying the field. This addresses a theoretical race
scenario pointed out by Jann, and makes the critical section safe wrt with
RT local_lock semantics after the conversion in patch 35.
Patch 34 changes preempt disable to migrate disable, so that the nested
list_lock spinlock is safe to take on RT. Because migrate_disable() is a
function call even on !RT, a small set of private wrappers is introduced
to keep using the cheaper preempt_disable() on !PREEMPT_RT configurations.
As of this patch, SLUB should be compatible with RT's lock semantics, to
the best of my knowledge.
Finally, patch 35 changes irq disabled sections that protect
kmem_cache_cpu fields in the slow paths, with a local lock. However on
PREEMPT_RT it means the lockless fast paths can now preempt slow paths
which don't expect that, so the local lock has to be taken also in the
fast paths and they are no longer lockless. It's up to RT folks to decide
if this is a good tradeoff. The patch also updates the locking
documentation in the file's comment.
The main results of this series:
* irq disabling is only done for minimum amount of time needed to
protect the kmem_cache_cpu data and as part of spin lock, local lock and
bit lock operations to make them irq-safe
* SLUB should be fully PREEMPT_RT compatible
This should have obvious implications for better preemptibility,
especially on RT.
Some details are different than how the previous SLUB RT tree patches were
implemented:
mm: sl[au]b: Change list_lock to raw_spinlock_t [2] - the SLAB part
can be dropped as a different patch restricts RT to SLUB anyway. And
after this series the list_lock in SLUB is never used with irqs disabled
before taking the lock so it doesn't have to be converted to
raw_spinlock_t.
mm: slub: Move discard_slab() invocations out of IRQ-off sections [3]
should be unnecessary as this series does move these invocations outside
irq disabled sections in a different way.
The remaining patches to upstream from the RT tree are small ones related
to KConfig. The patch that restricts PREEMPT_RT to SLUB (not SLAB or
SLOB) makes sense. The patch that disables CONFIG_SLUB_CPU_PARTIAL with
PREEMPT_RT could perhaps be re-evaluated as the series addresses some
latency issues with it.

Subject: mm, slub: allocate private object map for debugfs listings
Slub has a static spinlock protected bitmap for marking which objects are
on freelist when it wants to list them, for situations where dynamically
allocating such map can lead to recursion or locking issues, and on-stack
bitmap would be too large.
The handlers of debugfs files alloc_traces and free_traces also currently
use this shared bitmap, but their syscall context makes it straightforward
to allocate a private map before entering locked sections, so switch these
processing paths to use a private bitmap.

Subject: mm, slub: allocate private object map for validate_slab_cache()
validate_slab_cache() is called either to handle a sysfs write, or from a
self-test context. In both situations it's straightforward to preallocate
a private object bitmap instead of grabbing the shared static one meant
for critical sections, so let's do that.

Subject: mm, slub: don't disable irq for debug_check_no_locks_freed()
In slab_free_hook() we disable irqs around the
debug_check_no_locks_freed() call, which is unnecessary, as irqs are
already being disabled inside the call. This seems to be leftover from
the past where there were more calls inside the irq disabled sections.
Remove the irq disable/enable operations.
Mel noted:

Subject: mm, slub: remove redundant unfreeze_partials() from put_cpu_partial()
Commit d6e0b7fa1186 ("slub: make dead caches discard free slabs
immediately") introduced cpu partial flushing for kmemcg caches, based on
setting the target cpu_partial to 0 and adding a flushing check in
put_cpu_partial(). This code that sets cpu_partial to 0 was later moved
by c9fc586403e7 ("slab: introduce __kmemcg_cache_deactivate()") and
ultimately removed by 9855609bde03 ("mm: memcg/slab: use a single set of
kmem_caches for all accounted allocations"). However the check and flush
in put_cpu_partial() was never removed, although it's effectively a dead
code. So this patch removes it.
Note that d6e0b7fa1186 also added preempt_disable()/enable() to
unfreeze_partials() which could be thus also considered unnecessary. But
further patches will rely on it, so keep it.

Subject: mm, slub: unify cmpxchg_double_slab() and __cmpxchg_double_slab()
These functions differ only in irq disabling in the slow path. We can
create a common function with an extra bool parameter to control the irq
disabling. As the functions are inline and the parameter compile-time
constant, there will be no runtime overhead due to this change.
Also change the DEBUG_VM based irqs disable assert to the more standard
lockdep_assert based one.

The later patches will need more fine grained control over individual

is a first preparatory step with no functional change.
This adds a goto label that appears unnecessary at this point, but will be
useful for later changes.

The later patches will need more fine grained control over individual

dissolve it there. This is a preparatory step with no functional change.
The only minor change is moving WARN_ON_ONCE() for using a constructor
together with __GFP_ZERO to new_slab(), which makes it somewhat less
frequent, but still able to catch a development change introducing a
systematic misuse.

Subject: mm, slub: return slab page from get_partial() and set c->page afterwards
The function get_partial() finds a suitable page on a partial list,
acquires and returns its freelist and assigns the page pointer to
kmem_cache_cpu. In later patch we will need more control over the
kmem_cache_cpu.page assignment, so instead of passing a kmem_cache_cpu
pointer, pass a pointer to a pointer to a page that get_partial() can fill
and the caller can assign the kmem_cache_cpu.page pointer. No functional
change as all of this still happens with disabled IRQs.

Subject: mm, slub: restructure new page checks in ___slab_alloc()
When we allocate slab object from a newly acquired page (from node's
partial list or page allocator), we usually also retain the page as a new
percpu slab. There are two exceptions - when pfmemalloc status of the
page doesn't match our gfp flags, or when the cache has debugging enabled.
The current code for these decisions is not easy to follow, so restructure
it and add comments. The new structure will also help with the following
changes. No functional change.

Subject: mm, slub: simplify kmem_cache_cpu and tid setup
In slab_alloc_node() and do_slab_free() fastpaths we need to guarantee
that our kmem_cache_cpu pointer is from the same cpu as the tid value.
Currently that's done by reading the tid first using this_cpu_read(), then
the kmem_cache_cpu pointer and verifying we read the same tid using the
pointer and plain READ_ONCE().
This can be simplified to just fetching kmem_cache_cpu pointer and then
reading tid using the pointer. That guarantees they are from the same
cpu. We don't need to read the tid using this_cpu_read() because the
value will be validated by this_cpu_cmpxchg_double(), making sure we are
on the correct cpu and the freelist didn't change by anyone preempting us
since reading the tid.

Subject: mm, slub: move disabling/enabling irqs to ___slab_alloc()
Currently __slab_alloc() disables irqs around the whole ___slab_alloc().
This includes cases where this is not needed, such as when the allocation
ends up in the page allocator and has to awkwardly enable irqs back based
on gfp flags. Also the whole kmem_cache_alloc_bulk() is executed with
irqs disabled even when it hits the __slab_alloc() slow path, and long
periods with disabled interrupts are undesirable.
As a first step towards reducing irq disabled periods, move irq handling
into ___slab_alloc(). Callers will instead prevent the s->cpu_slab percpu
pointer from becoming invalid via get_cpu_ptr(), thus preempt_disable().
This does not protect against modification by an irq handler, which is
still done by disabled irq for most of ___slab_alloc(). As a small
immediate benefit, slab_out_of_memory() from ___slab_alloc() is now called
with irqs enabled.
kmem_cache_alloc_bulk() disables irqs for its fastpath and then re-enables
them before calling ___slab_alloc(), which then disables them at its
discretion. The whole kmem_cache_alloc_bulk() operation also disables
preemption.
When ___slab_alloc() calls new_slab() to allocate a new page, re-enable
preemption, because new_slab() will re-enable interrupts in contexts that
allow blocking (this will be improved by later patches).
The patch itself will thus increase overhead a bit due to disabled
preemption (on configs where it matters) and increased disabling/enabling
irqs in kmem_cache_alloc_bulk(), but that will be gradually improved in
the following patches.
Note in __slab_alloc() we need to change the #ifdef CONFIG_PREEMPT guard
to CONFIG_PREEMPT_COUNT to make sure preempt disable/enable is properly
paired in all configurations. On configs without involuntary preemption
and debugging the re-read of kmem_cache_cpu pointer is still compiled out
as it was before.

Subject: mm, slub: do initial checks in ___slab_alloc() with irqs enabled
As another step of shortening irq disabled sections in ___slab_alloc(),
delay disabling irqs until we pass the initial checks if there is a cached
percpu slab and it's suitable for our allocation.
Now we have to recheck c->page after actually disabling irqs as an
allocation in irq handler might have replaced it.
Because we call pfmemalloc_match() as one of the checks, we might hit
VM_BUG_ON_PAGE(!PageSlab(page)) in PageSlabPfmemalloc in case we get
interrupted and the page is freed. Thus introduce a
pfmemalloc_match_unsafe() variant that lacks the PageSlab check.

Subject: mm, slub: move disabling irqs closer to get_partial() in ___slab_alloc()
Continue reducing the irq disabled scope. Check for per-cpu partial slabs
with first with irqs enabled and then recheck with irqs disabled before
grabbing the slab page. Mostly preparatory for the following patches.

Subject: mm, slub: restore irqs around calling new_slab()
allocate_slab() currently re-enables irqs before calling to the page
allocator. It depends on gfpflags_allow_blocking() to determine if it's
safe to do so. Now we can instead simply restore irq before calling it
through new_slab(). The other caller early_kmem_cache_node_alloc() is
unaffected by this.

Subject: mm, slub: validate slab from partial list or page allocator before making it cpu slab
When we obtain a new slab page from node partial list or page allocator,
we assign it to kmem_cache_cpu, perform some checks, and if they fail, we
undo the assignment.
In order to allow doing the checks without irq disabled, restructure the
code so that the checks are done first, and kmem_cache_cpu.page assignment
only after they pass.

Subject: mm, slub: check new pages with restored irqs
Building on top of the previous patch, re-enable irqs before checking new
pages. alloc_debug_processing() is now called with enabled irqs so we
need to remove VM_BUG_ON(!irqs_disabled()); in check_slab() - there
doesn't seem to be a need for it anyway.

Subject: mm, slub: stop disabling irqs around get_partial()
The function get_partial() does not need to have irqs disabled as a whole.
It's sufficient to convert spin_lock operations to their irq
saving/restoring versions.
As a result, it's now possible to reach the page allocator from the slab
allocator without disabling and re-enabling interrupts on the way.

Subject: mm, slub: move reset of c->page and freelist out of deactivate_slab()
deactivate_slab() removes the cpu slab by merging the cpu freelist with
slab's freelist and putting the slab on the proper node's list. It also
sets the respective kmem_cache_cpu pointers to NULL.
By extracting the kmem_cache_cpu operations from the function, we can make
it not dependent on disabled irqs.
Also if we return a single free pointer from ___slab_alloc, we no longer
have to assign kmem_cache_cpu.page before deactivation or care if somebody
preempted us and assigned a different page to our kmem_cache_cpu in the
process.

Subject: mm, slub: make locking in deactivate_slab() irq-safe
dectivate_slab() now no longer touches the kmem_cache_cpu structure, so it
will be possible to call it with irqs enabled. Just convert the spin_lock
calls to their irq saving/restoring variants to make it irq-safe.
Note we now have to use cmpxchg_double_slab() for irq-safe slab_lock(),
because in some situations we don't take the list_lock, which would
disable irqs.

Subject: mm, slub: call deactivate_slab() without disabling irqs
The function is now safe to be called with irqs enabled, so move the calls
outside of irq disabled sections.
When called from ___slab_alloc() -> flush_slab() we have irqs disabled, so
to reenable them before deactivate_slab() we need to open-code
flush_slab() in ___slab_alloc() and reenable irqs after modifying the
kmem_cache_cpu fields. But that means a IRQ handler meanwhile might have
assigned a new page to kmem_cache_cpu.page so we have to retry the whole
check.
The remaining callers of flush_slab() are the IPI handler which has
disabled irqs anyway, and slub_cpu_dead() which will be dealt with in the
following patch.

Subject: mm, slub: move irq control into unfreeze_partials()
unfreeze_partials() can be optimized so that it doesn't need irqs disabled
for the whole time. As the first step, move irq control into the function
and remove it from the put_cpu_partial() caller.

Instead of iterating through the live percpu partial list, detach it from
the kmem_cache_cpu at once. This is simpler and will allow further
optimization.

Subject: mm, slub: separate detaching of partial list in unfreeze_partials() from unfreezing
Unfreezing partial list can be split to two phases - detaching the list
from struct kmem_cache_cpu, and processing the list. The whole operation
does not need to be protected by disabled irqs. Restructure the code to
separate the detaching (with disabled irqs) and unfreezing (with irq
disabling to be reduced in the next patch).
Also, unfreeze_partials() can be called from another cpu on behalf of a
cpu that is being offlined, where disabling irqs on the local cpu has no
sense, so restructure the code as follows:
- __unfreeze_partials() is the bulk of unfreeze_partials() that processes the
detached percpu partial list
- unfreeze_partials() detaches list from current cpu with irqs disabled and
calls __unfreeze_partials()
- unfreeze_partials_cpu() is to be called for the offlined cpu so it needs no
irq disabling, and is called from __flush_cpu_slab()
- flush_cpu_slab() is for the local cpu thus it needs to call
unfreeze_partials(). So it can't simply call
__flush_cpu_slab(smp_processor_id()) anymore and we have to open-code the
proper calls.

Subject: mm, slub: only disable irq with spin_lock in __unfreeze_partials()
__unfreeze_partials() no longer needs to have irqs disabled, except for
making the spin_lock operations irq-safe, so convert the spin_locks
operations and remove the separate irq handling.

Subject: mm, slub: don't disable irqs in slub_cpu_dead()
slub_cpu_dead() cleans up for an offlined cpu from another cpu and calls
only functions that are now irq safe, so we don't need to disable irqs
anymore.

Subject: mm, slab: make flush_slab() possible to call with irqs enabled
Currently flush_slab() is always called with disabled IRQs if it's needed,
but the following patches will change that, so add a parameter to control
IRQ disabling within the function, which only protects the kmem_cache_cpu
manipulation and not the call to deactivate_slab() which doesn't need it.

Subject: mm: slub: move flush_cpu_slab() invocations __free_slab() invocations out of IRQ context
flush_all() flushes a specific SLAB cache on each CPU (where the cache is
present). The deactivate_slab()/__free_slab() invocation happens within
IPI handler and is problematic for PREEMPT_RT.
The flush operation is not a frequent operation or a hot path. The
per-CPU flush operation can be moved to within a workqueue.

Subject: mm, slub: optionally save/restore irqs in slab_[un]lock()/
For PREEMPT_RT we will need to disable irqs for this bit spinlock. As a
preparation, add a flags parameter, and an internal version that takes
additional bool parameter to control irq saving/restoring (the flags
parameter is compile-time unused if the bool is a constant false).
Convert ___cmpxchg_double_slab(), which also comes with the same bool
parameter, to use the internal version.

Subject: mm, slub: make slab_lock() disable irqs with PREEMPT_RT
We need to disable irqs around slab_lock() (a bit spinlock) to make it
irq-safe. The calls to slab_lock() are nested under spin_lock_irqsave()
which doesn't disable irqs on PREEMPT_RT, so add explicit disabling with
PREEMPT_RT.
We also distinguish cmpxchg_double_slab() where we do the disabling
explicitly and __cmpxchg_double_slab() for contexts with already disabled
irqs. However these context are also typically spin_lock_irqsave() thus
insufficient on PREEMPT_RT. Thus, change __cmpxchg_double_slab() to be
same as cmpxchg_double_slab() on PREEMPT_RT.

From: Vlastimil Babka <vbabka@suse.cz>
Subject: mm, slub: protect put_cpu_partial() with disabled irqs instead of cmpxchg
Jann Horn reported [1] the following theoretically possible race:
task A: put_cpu_partial() calls preempt_disable()
task A: oldpage = this_cpu_read(s->cpu_slab->partial)
interrupt: kfree() reaches unfreeze_partials() and discards the page
task B (on another CPU): reallocates page as page cache
task A: reads page->pages and page->pobjects, which are actually
halves of the pointer page->lru.prev
task B (on another CPU): frees page
interrupt: allocates page as SLUB page and places it on the percpu partial list
task A: this_cpu_cmpxchg() succeeds
which would cause page->pages and page->pobjects to end up containing
halves of pointers that would then influence when put_cpu_partial()
happens and show up in root-only sysfs files. Maybe that's acceptable,
I don't know. But there should probably at least be a comment for now
to point out that we're reading union fields of a page that might be
in a completely different state.
Additionally, the this_cpu_cmpxchg() approach in put_cpu_partial() is only
safe against s->cpu_slab->partial manipulation in ___slab_alloc() if the
latter disables irqs, otherwise a __slab_free() in an irq handler could
call put_cpu_partial() in the middle of ___slab_alloc() manipulating
->partial and corrupt it. This becomes an issue on RT after a local_lock
is introduced in later patch. The fix means taking the local_lock also in
put_cpu_partial() on RT.
After debugging this issue, Mike Galbraith suggested [2] that to avoid
different locking schemes on RT and !RT, we can just protect
put_cpu_partial() with disabled irqs (to be converted to
local_lock_irqsave() later) everywhere. This should be acceptable as it's
not a fast path, and moving the actual partial unfreezing outside of the
irq disabled section makes it short, and with the retry loop gone the code
can be also simplified. In addition, the race reported by Jann should no
longer be possible.

Subject: mm, slub: use migrate_disable() on PREEMPT_RT
We currently use preempt_disable() (directly or via get_cpu_ptr()) to
stabilize the pointer to kmem_cache_cpu. On PREEMPT_RT this would be
incompatible with the list_lock spinlock. We can use migrate_disable()
instead, but that increases overhead on !PREEMPT_RT as it's an
unconditional function call.
In order to get the best available mechanism on both PREEMPT_RT and
!PREEMPT_RT, introduce private slub_get_cpu_ptr() and slub_put_cpu_ptr()
wrappers and use them.

Subject: mm, slub: convert kmem_cpu_slab protection to local_lock
Embed local_lock into struct kmem_cpu_slab and use the irq-safe versions
of local_lock instead of plain local_irq_save/restore. On !PREEMPT_RT
that's equivalent, with better lockdep visibility. On PREEMPT_RT that
means better preemption.
However, the cost on PREEMPT_RT is the loss of lockless fast paths which
only work with cpu freelist. Those are designed to detect and recover
from being preempted by other conflicting operations (both fast or slow
path), but the slow path operations assume they cannot be preempted by a
fast path operation, which is guaranteed naturally with disabled irqs.
With local locks on PREEMPT_RT, the fast paths now also need to take the
local lock to avoid races.
In the allocation fastpath slab_alloc_node() we can just defer to the
slowpath __slab_alloc() which also works with cpu freelist, but under the
local lock. In the free fastpath do_slab_free() we have to add a new
local lock protected version of freeing to the cpu freelist, as the
existing slowpath only works with the page freelist.
Also update the comment about locking scheme in SLUB to reflect changes
done by this series.

From: Gavin Shan <gshan@redhat.com>
Subject: mm/debug_vm_pgtable: introduce struct pgtable_debug_args
Patch series "mm/debug_vm_pgtable: Enhancements", v6.
There are a couple of issues with current implementations and this series
tries to resolve the issues:
(a) All needed information are scattered in variables, passed to various
test functions. The code is organized in pretty much relaxed fashion.
(b) The page isn't allocated from buddy during page table entry modifying
tests. The page can be invalid, conflicting to the implementations
of set_xxx_at() on ARM64. The target page is accessed so that the
iCache can be flushed when execution permission is given on ARM64.
Besides, the target page can be unmapped and accessing to it causes
kernel crash.
"struct pgtable_debug_args" is introduced to address issue (a). For issue
(b), the used page is allocated from buddy in page table entry modifying
tests. The corresponding tets will be skipped if we fail to allocate the
(huge) page. For other test cases, the original page around to kernel
symbol (@start_kernel) is still used.
The patches are organized as below. PATCH[2-10] could be combined to one
patch, but it will make the review harder:
PATCH[1] introduces "struct pgtable_debug_args" as place holder of all
needed information. With it, the old and new implementation
can coexist.
PATCH[2-10] uses "struct pgtable_debug_args" in various test functions.
PATCH[11] removes the unused code for old implementation.
PATCH[12] fixes the issue of corrupted page flag for ARM64
This patch (of 6):
In debug_vm_pgtable(), there are many local variables introduced to track
the needed information and they are passed to the functions for various
test cases. It'd better to introduce a struct as place holder for these
information. With it, what the tests functions need is the struct. In
this way, the code is simplified and easier to be maintained.
Besides, set_xxx_at() could access the data on the corresponding pages in
the page table modifying tests. So the accessed pages in the tests should
have been allocated from buddy. Otherwise, we're accessing pages that
aren't owned by us. This causes issues like page flag corruption or
kernel crash on accessing unmapped page when CONFIG_DEBUG_PAGEALLOC is
enabled.
This introduces "struct pgtable_debug_args". The struct is initialized
and destroyed, but the information in the struct isn't used yet. It will
be used in subsequent patches.

Subject: mm/debug_vm_pgtable: use struct pgtable_debug_args in basic tests
This uses struct pgtable_debug_args in the basic test functions. The
unused variables @pgd_aligned and @p4d_aligned in debug_vm_pgtable() are
dropped.

swap_migration_tests() as set_pte_at() is used there.

Subject: mm/debug_vm_pgtable: use struct pgtable_debug_args in PTE modifying tests
This uses struct pgtable_debug_args in PTE modifying tests. The allocated
page is used as set_pte_at() is used there. The tests are skipped if the
allocated page doesn't exist. It's notable that args->ptep need to be
mapped before the tests. The reason why we don't map args->ptep at the
beginning is PTE entry is only mapped and accessible in atomic context
when CONFIG_HIGHPTE is enabled. So we avoid to do that so that atomic
context is only enabled if needed.
Besides, the unused variable @pte_aligned and @ptep in debug_vm_pgtable()
are dropped.

Subject: mm/debug_vm_pgtable: use struct pgtable_debug_args in PMD modifying tests
This uses struct pgtable_debug_args in PMD modifying tests. The allocated
huge page is used when set_pmd_at() is used. The corresponding tests are
skipped if the huge page doesn't exist. Besides, the unused variable
@pmd_aligned in debug_vm_pgtable() is dropped.

Subject: mm/debug_vm_pgtable: use struct pgtable_debug_args in PGD and P4D modifying tests
This uses struct pgtable_debug_args in PGD/P4D modifying tests. No
allocated huge page is used in these tests. Besides, the unused variable
@saved_p4dp and @saved_pudp are dropped.

The variables used by old implementation isn't needed as we switched to
"struct pgtable_debug_args". Lets remove them and related code in
debug_vm_pgtable().

From: Gavin Shan <gshan@redhat.com>
Subject: mm/debug_vm_pgtable: fix corrupted page flag
In page table entry modifying tests, set_xxx_at() are used to populate
the page table entries. On ARM64, PG_arch_1 (PG_dcache_clean) flag is
set to the target page flag if execution permission is given. The logic
exits since commit 4f04d8f00545 ("arm64: MMU definitions"). The page
flag is kept when the page is free'd to buddy's free area list. However,
it will trigger page checking failure when it's pulled from the buddy's
free area list, as the following warning messages indicate.
BUG: Bad page state in process memhog pfn:08000
page:0000000015c0a628 refcount:0 mapcount:0 \
mapping:0000000000000000 index:0x1 pfn:0x8000
flags: 0x7ffff8000000800(arch_1|node=0|zone=0|lastcpupid=0xfffff)
raw: 07ffff8000000800 dead000000000100 dead000000000122 0000000000000000
raw: 0000000000000001 0000000000000000 00000000ffffffff 0000000000000000
page dumped because: PAGE_FLAGS_CHECK_AT_PREP flag(s) set
This fixes the issue by clearing PG_arch_1 through flush_dcache_page()
after set_xxx_at() is called. For architectures other than ARM64, the
unexpected overhead of cache flushing is acceptable.

Subject: mm: report a more useful address for reclaim acquisition
A recent lockdep report included these lines:
[ 96.177910] 3 locks held by containerd/770:
[ 96.177934] #0: ffff88810815ea28 (&mm->mmap_lock#2){++++}-{3:3},

[ 96.178057] #2: ffffffff82955ba0 (fs_reclaim){+.+.}-{0:0}, at:
__fs_reclaim_acquire+0x5/0x30
While it was not useful to that bug report to know where the reclaim lock
had been acquired, it might be useful under other circumstances. Allow
the caller of __fs_reclaim_acquire to specify the instruction pointer to
use.

Subject: writeback: track number of inodes under writeback
Patch series "writeback: Fix bandwidth estimates", v4.
Fix estimate of writeback throughput when device is not fully busy doing
writeback. Michael Stapelberg has reported that such workload (e.g.
generated by linking) tends to push estimated throughput down to 0 and as
a result writeback on the device is practically stalled.
The first three patches fix the reported issue, the remaining two patches
are unrelated cleanups of problems I've noticed when reading the code.
This patch (of 4):
Track number of inodes under writeback for each bdi_writeback structure.
We will use this to decide whether wb does any IO and so we can estimate
its writeback throughput. In principle we could use number of pages under
writeback (WB_WRITEBACK counter) for this however normal percpu counter
reads are too inaccurate for our purposes and summing the counter is too
expensive.

Subject: writeback: reliably update bandwidth estimation
Currently we trigger writeback bandwidth estimation from
balance_dirty_pages() and from wb_writeback(). However neither of these
need to trigger when the system is relatively idle and writeback is
triggered e.g. from fsync(2). Make sure writeback estimates happen
reliably by triggering them from do_writepages().

Subject: writeback: fix bandwidth estimate for spiky workload
Michael Stapelberg has reported that for workload with short big spikes of
writes (GCC linker seem to trigger this frequently) the write throughput
is heavily underestimated and tends to steadily sink until it reaches
zero. This has rather bad impact on writeback throttling (causing
stalls). The problem is that writeback throughput estimate gets updated
at most once per 200 ms. One update happens early after we submit pages
for writeback (at that point writeout of only small fraction of pages is
completed and thus observed throughput is tiny). Next update happens only
during the next write spike (updates happen only from inode writeback and
dirty throttling code) and if that is more than 1s after previous spike,
we decide system was idle and just ignore whatever was written until this
moment.
Fix the problem by making sure writeback throughput estimate is also
updated shortly after writeback completes to get reasonable estimate of
throughput for spiky workloads.

Rename domain_update_bandwidth() to domain_update_dirty_limit(). The
original name is a misnomer. The function has nothing to do with a
bandwidth, it updates dirty limits.

Subject: writeback: use READ_ONCE for unlocked reads of writeback stats
We do some unlocked reads of writeback statistics like
avg_write_bandwidth, dirty_ratelimit, or bw_time_stamp. Generally we are
fine with getting somewhat out-of-date values but actually getting
different values in various parts of the functions because the compiler
decided to reload value from original memory location could confuse
calculations. Use READ_ONCE for these unlocked accesses and WRITE_ONCE
for the updates to be on the safe side.

Subject: mm: remove irqsave/restore locking from contexts with irqs enabled
The page cache deletion paths all have interrupts enabled, so no need to
use irqsafe/irqrestore locking variants.
They used to have irqs disabled by the memcg lock added in commit
c4843a7593a9 ("memcg: add per cgroup dirty page accounting"), but that has
since been replaced by memcg taking the page lock instead, commit
0a31bc97c80c ("mm: memcontrol: rewrite uncharge AP").

Subject: fs: drop_caches: fix skipping over shadow cache inodes
When drop_caches truncates the page cache in an inode it also includes any
shadow entries for evicted pages. However, there is a preliminary check
on whether the inode has pages: if it has *only* shadow entries, it will
skip running truncation on the inode and leave it behind.
Fix the check to mapping_empty(), such that it runs truncation on any
inode that has cache entries at all.

Subject: fs: inode: count invalidated shadow pages in pginodesteal
pginodesteal is supposed to capture the impact that inode reclaim has on
the page cache state. Currently, it doesn't consider shadow pages that
get dropped this way, even though this can have a significant impact on
paging behavior, memory pressure calculations etc.
To improve visibility into these effects, make sure shadow pages get
counted when they get dropped through inode reclaim.
This changes the return value semantics of invalidate_mapping_pages()
semantics slightly, but the only two users are the inode shrinker itsel
and a usb driver that logs it for debugging purposes.

Subject: writeback: memcg: simplify cgroup_writeback_by_id
Currently cgroup_writeback_by_id calls mem_cgroup_wb_stats() to get dirty
pages for a memcg. However mem_cgroup_wb_stats() does a lot more than
just get the number of dirty pages. Just directly get the number of dirty
pages instead of calling mem_cgroup_wb_stats(). Also
cgroup_writeback_by_id() is only called for best-effort dirty flushing, so
remove the unused 'nr' parameter and no need to explicitly flush memcg
stats.

Patch series "Cleanups and fixup for gup".
This series contains cleanups to remove unneeded variable, useless BUG_ON
and use helper to improve readability. Also we fix a potential pgmap
refcnt leak. More details can be found in the respective changelogs.
This patch (of 5):
Since commit a2beb5f1efed ("mm: clean up the last pieces of page fault
accountings"), the local variable major is unused. Remove it.

Subject: mm: gup: fix potential pgmap refcnt leak in __gup_device_huge()
When failed to try_grab_page, put_dev_pagemap() is missed. So pgmap
refcnt will leak in this case. Also we remove the check for pgmap against
NULL as it's also checked inside the put_dev_pagemap().

Subject: mm/gup: documentation corrections for gup/pup
Patch series "A few gup refactorings and documentation updates", v3.
While reviewing some of the other things going on around gup.c, I noticed
that the documentation was wrong for a few of the routines that I wrote.
And then I noticed that there was some significant code duplication too.
So this fixes those issues.
This is not entirely risk-free, but after looking closely at this, I think
it's actually a useful improvement, getting rid of the code duplication
here.
This patch (of 3):
The documentation for try_grab_compound_head() and try_grab_page() has
fallen a little out of date. Update and clarify a few points.
Also make it kerneldoc-correct, by adding @args documentation.

Subject: mm/gup: small refactoring: simplify try_grab_page()
try_grab_page() does the same thing as try_grab_compound_head(..., refs=1,
...), just with a different API. So there is a lot of code duplication
there.
Change try_grab_page() to call try_grab_compound_head(), while keeping the
API contract identical for callers.
Also, now that try_grab_compound_head() always has a caller, remove the
__maybe_unused annotation.

Subject: mm/gup: remove try_get_page(), call try_get_compound_head() directly
try_get_page() is very similar to try_get_compound_head(), and in fact
try_get_page() has fallen a little behind in terms of maintenance:
try_get_compound_head() handles speculative page references more
thoroughly.
There are only two try_get_page() callsites, so just call
try_get_compound_head() directly from those, and remove try_get_page()
entirely.
Also, seeing as how this changes try_get_compound_head() into a non-static
function, provide some kerneldoc documentation for it.

Subject: fs, mm: fix race in unlinking swapfile
We had a recurring situation in which admin procedures setting up
swapfiles would race with test preparation clearing away swapfiles; and
just occasionally that got stuck on a swapfile "(deleted)" which could
never be swapped off. That is not supposed to be possible.
2.6.28 commit f9454548e17c ("don't unlink an active swapfile") admitted
that it was leaving a race window open: now close it.
may_delete() makes the IS_SWAPFILE check (amongst many others) before
inode_lock has been taken on target: now repeat just that simple check in
vfs_unlink() and vfs_rename(), after taking inode_lock.
Which goes most of the way to fixing the race, but swapon() must also
check after it acquires inode_lock, that the file just opened has not
already been unlinked.

Subject: mm: delete unused get_kernel_page()
get_kernel_page() was added in 2012 by [1]. It was used for a while for
NFS, but then in 2014, a refactoring [2] removed all callers, and it has
apparently not been used since.
Remove get_kernel_page() because it has no callers.
[1] commit 18022c5d8627 ("mm: add get_kernel_page[s] for pinning of
kernel addresses for I/O")
[2] commit 91f79c43d1b5 ("new helper: iov_iter_get_pages_alloc()")

Subject: shmem: use raw_spinlock_t for ->stat_lock
Each CPU has SHMEM_INO_BATCH inodes available in `->ino_batch' which is
per-CPU. Access here is serialized by disabling preemption. If the pool
is empty, it gets reloaded from `->next_ino'. Access here is serialized
by ->stat_lock which is a spinlock_t and can not be acquired with disabled
preemption.
One way around it would make per-CPU ino_batch struct containing the inode
number a local_lock_t.
Another solution is to promote ->stat_lock to a raw_spinlock_t. The
critical sections are short. The mpol_put() must be moved outside of the
critical section to avoid invoking the destructor with disabled
preemption.

Patch series "Cleanups for shmem".
This series contains cleanups to remove unneeded variable, header file,
function forward declaration and so on. More details can be found in the
respective changelogs.
This patch (of 4):
The local variable ret is always equal to -ENOMEM and never touched. So
remove it and return -ENOMEM directly to simplify the code.

Subject: huge tmpfs: fix fallocate(vanilla) advance over huge pages
Patch series "huge tmpfs: shmem_is_huge() fixes and cleanups".
A series of huge tmpfs fixes and cleanups.
This patch (of 9):
shmem_fallocate() goes to a lot of trouble to leave its newly allocated
pages !Uptodate, partly to identify and undo them on failure, partly to
leave the overhead of clearing them until later. But the huge page case
did not skip to the end of the extent, walked through the tail pages one
by one, and appeared to work just fine: but in doing so, cleared and
Uptodated the huge page, so there was no way to undo it on failure.
And by setting Uptodate too soon, it messed up both its nr_falloced and
nr_unswapped counts, so that the intended "time to give up" heuristic did
not work at all.
Now advance immediately to the end of the huge extent, with a comment on
why this is more than just an optimization. But although this speeds up
huge tmpfs fallocation, it does leave the clearing until first use, and
some users may have come to appreciate slow fallocate but fast first use:
if they complain, then we can consider adding a pass to clear at the end.

Subject: huge tmpfs: fix split_huge_page() after FALLOC_FL_KEEP_SIZE
A successful shmem_fallocate() guarantees that the extent has been
reserved, even beyond i_size when the FALLOC_FL_KEEP_SIZE flag was used.
But that guarantee is broken by shmem_unused_huge_shrink()'s attempts to
split huge pages and free their excess beyond i_size; and by other uses of
split_huge_page() near i_size.
It's sad to add a shmem inode field just for this, but I did not find a
better way to keep the guarantee. A flag to say KEEP_SIZE has been used
would be cheaper, but I'm averse to unclearable flags. The fallocend
field is not perfect either (many disjoint ranges might be fallocated),
but good enough; and gains another use later on.

Subject: huge tmpfs: remove shrinklist addition from shmem_setattr()
There's a block of code in shmem_setattr() to add the inode to
shmem_unused_huge_shrink()'s shrinklist when lowering i_size: it dates
from before 5.7 changed truncation to do split_huge_page() for itself, and
should have been removed at that time.
I am over-stating that: split_huge_page() can fail (notably if there's an
extra reference to the page at that time), so there might be value in
retrying. But there were already retries as truncation worked through the
tails, and this addition risks repeating unsuccessful retries
indefinitely: I'd rather remove it now, and work on reducing the chance of
split_huge_page() failures separately, if we need to.

5.14 commit e6be37b2e7bd ("mm/huge_memory.c: add missing read-only THP
checking in transparent_hugepage_enabled()") added transhuge_vma_enabled()
as a wrapper for two very different checks (one check is whether the app
has marked its address range not to use THPs, the other check is whether
the app is running in a hierarchy that has been marked never to use THPs).
shmem_huge_enabled() prefers to show those two checks explicitly, as
before.

Subject: huge tmpfs: move shmem_huge_enabled() upwards
shmem_huge_enabled() is about to be enhanced into shmem_is_huge(), so that
it can be used more widely throughout: before making functional changes,
shift it to its final position (to avoid forward declaration).

Subject: huge tmpfs: SGP_NOALLOC to stop collapse_file() on race
khugepaged's collapse_file() currently uses SGP_NOHUGE to tell
shmem_getpage() not to try allocating a huge page, in the very unlikely
event that a racing hole-punch removes the swapped or fallocated page as
soon as i_pages lock is dropped.
We want to consolidate shmem's huge decisions, removing SGP_HUGE and
SGP_NOHUGE; but cannot quite persuade ourselves that it's okay to regress
the protection in this case - Yang Shi points out that the huge page would
remain indefinitely, charged to root instead of the intended memcg.
collapse_file() should not even allocate a small page in this case: why
proceed if someone is punching a hole? SGP_READ is almost the right flag
here, except that it optimizes away from a fallocated page, with NULL to
tell caller to fill with zeroes (like a hole); whereas collapse_file()'s
sequence relies on using a cache page. Add SGP_NOALLOC just for this.
There are too many consecutive "if (page"s there in shmem_getpage_gfp():
group it better; and fix the outdated "bring it back from swap" comment.

Subject: huge tmpfs: shmem_is_huge(vma, inode, index)
Extend shmem_huge_enabled(vma) to shmem_is_huge(vma, inode, index), so
that a consistent set of checks can be applied, even when the inode is
accessed through read/write syscalls (with NULL vma) instead of mmaps (the
index argument is seldom of interest, but required by mount option
"huge=within_size"). Clean up and rearrange the checks a little.
This then replaces the checks which shmem_fault() and shmem_getpage_gfp()
were making, and eliminates the SGP_HUGE and SGP_NOHUGE modes.
Replace a couple of 0s by explicit SHMEM_HUGE_NEVERs; and replace the
obscure !shmem_mapping() symlink check by explicit S_ISLNK() - nothing
else needs that symlink check, so leave it there in shmem_getpage_gfp().

Subject: huge tmpfs: decide stat.st_blksize by shmem_is_huge()
4.18 commit 89fdcd262fd4 ("mm: shmem: make stat.st_blksize return huge
page size if THP is on") added is_huge_enabled() to decide st_blksize: if
hugeness is to be defined per file, that will need to be replaced by
shmem_is_huge().
This does give a different answer (No) for small files on a
"huge=within_size" mount: but that can be considered a minor bugfix. And
a different answer (No) for default files on a "huge=advise" mount: I'm
reluctant to complicate it, just to reproduce the same debatable answer as
before.

Subject: shmem: shmem_writepage() split unlikely i915 THP
drivers/gpu/drm/i915/gem/i915_gem_shmem.c contains a shmem_writeback()
which calls shmem_writepage() from a shrinker: that usually works well
enough; but if /sys/kernel/mm/transparent_hugepage/shmem_enabled has been
set to "always" (intended to be usable) or "force" (forces huge everywhere
for easy testing), shmem_writepage() is surprised to be called with a huge
page, and crashes on the VM_BUG_ON_PAGE(PageCompound) (I did not find out
where the crash happens when CONFIG_DEBUG_VM is off).
LRU page reclaim always splits the shmem huge page first: I'd prefer not
to demand that of i915, so check and split compound in shmem_writepage().
Patch history: when first sent last year
http://lkml.kernel.org/r/alpine.LSU.2.11.2008301401390.5954@eggly.anvils
https://lore.kernel.org/linux-mm/20200919042009.bomzxmrg7%25akpm@linux-foundation.org/
Matthew Wilcox noticed that tail pages were wrongly left clean. This
version brackets the split with Set and Clear PageDirty as he suggested:
which works very well, even if it falls short of our aspirations. And
recently I realized that the crash is not limited to the testing option
"force", but affects "always" too: which is more important to fix.

Subject: mm, memcg: add mem_cgroup_disabled checks in vmpressure and swap-related functions
Add mem_cgroup_disabled check in vmpressure, mem_cgroup_uncharge_swap and
cgroup_throttle_swaprate functions. This minimizes the memcg overhead in
the pagefault and exit_mmap paths when memcgs are disabled using
cgroup_disable=memory command-line option.
This change results in ~2.1% overhead reduction when running PFT test [1]
comparing {CONFIG_MEMCG=n, CONFIG_MEMCG_SWAP=n} against {CONFIG_MEMCG=y,
CONFIG_MEMCG_SWAP=y, cgroup_disable=memory} configuration on an 8-core

Subject: mm, memcg: inline swap-related functions to improve disabled memcg config
Inline mem_cgroup_try_charge_swap, mem_cgroup_uncharge_swap and
cgroup_throttle_swaprate functions to perform mem_cgroup_disabled static
key check inline before calling the main body of the function. This
minimizes the memcg overhead in the pagefault and exit_mmap paths when
memcgs are disabled using cgroup_disable=memory command-line option. This
change results in ~1% overhead reduction when running PFT test [1]
comparing {CONFIG_MEMCG=n} against {CONFIG_MEMCG=y, cgroup_disable=memory}
configuration on an 8-core ARM64 Android device.

Subject: memcg: enable accounting for pids in nested pid namespaces
Commit 5d097056c9a0 ("kmemcg: account certain kmem allocations to memcg")
enabled memcg accounting for pids allocated from init_pid_ns.pid_cachep,
but forgot to adjust the setting for nested pid namespaces. As a result,
pid memory is not accounted exactly where it is really needed, inside
memcg-limited containers with their own pid namespaces.
Pid was one the first kernel objects enabled for memcg accounting.
init_pid_ns.pid_cachep marked by SLAB_ACCOUNT and we can expect that any
new pids in the system are memcg-accounted.
Though recently I've noticed that it is wrong. nested pid namespaces
creates own slab caches for pid objects, nested pids have increased size
because contain id both for all parent and for own pid namespaces. The
problem is that these slab caches are _NOT_ marked by SLAB_ACCOUNT, as a
result any pids allocated in nested pid namespaces are not
memcg-accounted.
Pid struct in nested pid namespace consumes up to 500 bytes memory, 100000
such objects gives us up to ~50Mb unaccounted memory, this allow container
to exceed assigned memcg limits.

Subject: memcg: switch lruvec stats to rstat
The commit 2d146aa3aa84 ("mm: memcontrol: switch to rstat") switched memcg
stats to rstat infrastructure but skipped the conversion of the lruvec
stats as such stats are read in the performance critical code paths and
flushing stats may have impacted the performances of the applications.
This patch converts the lruvec stats to rstat and later patches add
mechanisms to keep the performance impact to minimum.
The rstat conversion comes with the price i.e. memory cost. Effectively
this patch reverts the savings done by the commit f3344adf38bd ("mm:
memcontrol: optimize per-lruvec stats counter memory usage"). However
this cost is justified due to negative impact of the inaccurate lruvec
stats on many heuristics. One such case is reported in [1].
The memory reclaim code is filled with plethora of heuristics and many of
those heuristics reads the lruvec stats. So, inaccurate stats can make
such heuristics ineffective. [1] reports the impact of inaccurate lruvec
stats on the "cache trim mode" heuristic. Inaccurate lruvec stats can
impact the deactivation and aging anon heuristics as well.

Subject: memcg: infrastructure to flush memcg stats
At the moment memcg stats are read in four contexts:
1. memcg stat user interfaces
2. dirty throttling
3. page fault
4. memory reclaim
Currently the kernel flushes the stats for first two cases. Flushing the
stats for remaining two casese may have performance impact. Always
flushing the memcg stats on the page fault code path may negatively
impacts the performance of the applications. In addition flushing in the
memory reclaim code path, though treated as slowpath, can become the
source of contention for the global lock taken for stat flushing because
when system or memcg is under memory pressure, many tasks may enter the
reclaim path.
This patch uses following mechanisms to solve these challenges:
1. Periodically flush the stats from root memcg every 2 seconds. This
will time limit the out of sync stats.
2. Asynchronously flush the stats after fixed number of stat updates.
In the worst case the stat can be out of sync by O(nr_cpus * BATCH) for
2 seconds.
3. For avoiding thundering herd to flush the stats particularly from
the memory reclaim context, introduce memcg local spinlock and let only
one flusher active at a time. This could have been done through
cgroup_rstat_lock lock but that lock is used by other subsystem and for
userspace reading memcg stats. So, it is better to keep flushers
introduced by this patch decoupled from cgroup_rstat_lock. However we
would have to use irqsafe version of rstat flush but that is fine as
this code path will be flushing for whole tree and do the work for
everyone. No one will be waiting for that worker.

Subject: memcg: charge fs_context and legacy_fs_context
This patch adds accounting flags to fs_context and legacy_fs_context
allocation sites so that kernel could correctly charge these objects.
We have written a PoC to demonstrate the effect of the missing-charging
bugs. The PoC takes around 1,200MB unaccounted memory, while it is
charged for only 362MB memory usage. We evaluate the PoC on QEMU x86_64
v5.2.90 + Linux kernel v5.10.19 + Debian buster. All the limitations
including ulimits and sysctl variables are set as default. Specifically,
the hard NOFILE limit and nr_open in sysctl are both 1,048,576.

Subject: memcg: enable accounting for mnt_cache entries
Patch series "memcg accounting from OpenVZ", v7.
OpenVZ uses memory accounting 20+ years since v2.2.x linux kernels.
Initially we used our own accounting subsystem, then partially committed
it to upstream, and a few years ago switched to cgroups v1. Now we're
rebasing again, revising our old patches and trying to push them upstream.
We try to protect the host system from any misuse of kernel memory
allocation triggered by untrusted users inside the containers.
Patch-set is addressed mostly to cgroups maintainers and cgroups@ mailing
list, though I would be very grateful for any comments from maintainersi
of affected subsystems or other people added in cc:
Compared to the upstream, we additionally account the following kernel objects:
- network devices and its Tx/Rx queues
- ipv4/v6 addresses and routing-related objects
- inet_bind_bucket cache objects
- VLAN group arrays
- ipv6/sit: ip_tunnel_prl
- scm_fp_list objects used by SCM_RIGHTS messages of Unix sockets
- nsproxy and namespace objects itself
- IPC objects: semaphores, message queues and share memory segments
- mounts
- pollfd and select bits arrays
- signals and posix timers
- file lock
- fasync_struct used by the file lease code and driver's fasync queues
- tty objects
- per-mm LDT
We have an incorrect/incomplete/obsoleted accounting for few other kernel
objects: sk_filter, af_packets, netlink and xt_counters for iptables.
They require rework and probably will be dropped at all.
Also we're going to add an accounting for nft, however it is not ready
yet.
We have not tested performance on upstream, however, our performance team
compares our current RHEL7-based production kernel and reports that they
are at least not worse as the according original RHEL7 kernel.
This patch (of 10):
The kernel allocates ~400 bytes of 'struct mount' for any new mount.
Creating a new mount namespace clones most of the parent mounts, and this
can be repeated many times. Additionally, each mount allocates up to
PATH_MAX=4096 bytes for mnt->mnt_devname.
It makes sense to account for these allocations to restrict the host's
memory consumption from inside the memcg-limited container.

Subject: memcg: enable accounting for pollfd and select bits arrays
User can call select/poll system calls with a large number of assigned
file descriptors and force kernel to allocate up to several pages of
memory till end of these sleeping system calls. We have here long-living
unaccounted per-task allocations.
It makes sense to account for these allocations to restrict the host's
memory consumption from inside the memcg-limited container.

Subject: memcg: enable accounting for file lock caches
User can create file locks for each open file and force kernel to allocate
small but long-living objects per each open file.
It makes sense to account for these objects to limit the host's memory
consumption from inside the memcg-limited container.

Subject: memcg: enable accounting for fasync_cache
fasync_struct is used by almost all character device drivers to set up the
fasync queue, and for regular files by the file lease code. This
structure is quite small but long-living and it can be assigned for any
open file.
It makes sense to account for its allocations to restrict the host's
memory consumption from inside the memcg-limited container.

Subject: memcg: enable accounting for new namesapces and struct nsproxy
Container admin can create new namespaces and force kernel to allocate up
to several pages of memory for the namespaces and its associated
structures.
Net and uts namespaces have enabled accounting for such allocations. It
makes sense to account for rest ones to restrict the host's memory
consumption from inside the memcg-limited container.

When user creates IPC objects it forces kernel to allocate memory for
these long-living objects.
It makes sense to account them to restrict the host's memory consumption
from inside the memcg-limited container.
This patch enables accounting for IPC shared memory segments, messages
semaphores and semaphore's undo lists.

Subject: memcg: enable accounting for signals
When a user send a signal to any another processes it forces the kernel to
allocate memory for 'struct sigqueue' objects. The number of signals is
limited by RLIMIT_SIGPENDING resource limit, but even the default settings
allow each user to consume up to several megabytes of memory.
It makes sense to account for these allocations to restrict the host's
memory consumption from inside the memcg-limited container.

Subject: memcg: enable accounting for posix_timers_cache slab
A program may create multiple interval timers using timer_create(). For
each timer the kernel preallocates a "queued real-time signal",
Consequently, the number of timers is limited by the RLIMIT_SIGPENDING
resource limit. The allocated object is quite small, ~250 bytes, but even
the default signal limits allow to consume up to 100 megabytes per user.
It makes sense to account for them to limit the host's memory consumption
from inside the memcg-limited container.

Subject: memcg: enable accounting for ldt_struct objects
Each task can request own LDT and force the kernel to allocate up to 64Kb
memory per-mm.
There are legitimate workloads with hundreds of processes and there can be
hundreds of workloads running on large machines. The unaccounted memory
can cause isolation issues between the workloads particularly on highly
utilized machines.
It makes sense to account for this objects to restrict the host's memory
consumption from inside the memcg-limited container.

Subject: memcg: cleanup racy sum avoidance code
We used to have per-cpu memcg and lruvec stats and the readers have to
traverse and sum the stats from each cpu. This summing was racy and may
expose transient negative values. So, an explicit check was added to
avoid such scenarios. Now these stats are moved to rstat infrastructure
and are no more per-cpu, so we can remove the fixup for transient negative
values.

Subject: memcg: replace in_interrupt() by !in_task() in active_memcg()
set_active_memcg() uses in_interrupt() check to select proper storage for
cgroup: pointer on task struct or per-cpu pointer.
It isn't fully correct: obsoleted in_interrupt() includes tasks with
disabled BH. It's better to use '!in_task()' instead.

swap to be preferred in some systems. We should also change the memcg

Thomas and Vlastimil have noticed that the comment in drain_local_stock
doesn't quite make sense. It talks about a synchronization with the
memory hotplug but there is no actual memory hotplug involvement here. I
meant to talk about cpu hotplug here. Fix that up and hopefuly make the
comment more helpful by referencing the cpu hotplug callback as well.

Subject: memcg: make memcg->event_list_lock irqsafe
The memcg->event_list_lock is usually taken in the normal context but when
the userspace closes the corresponding eventfd, eventfd_release through
memcg_event_wake takes memcg->event_list_lock with interrupts disabled.
This is not an issue on its own but it creates a nested dependency from
eventfd_ctx->wqh.lock to memcg->event_list_lock.
Independently, for unrelated eventfd, eventfd_signal() can be called in
the irq context, thus making eventfd_ctx->wqh.lock an irq lock. For
example, FPGA DFL driver, VHOST VPDA driver and couple of VFIO drivers.
This will force memcg->event_list_lock to be an irqsafe lock as well.
One way to break the nested dependency between eventfd_ctx->wqh.lock and
memcg->event_list_lock is to add an indirection. However the simplest
solution would be to make memcg->event_list_lock irqsafe. This is cgroup
v1 feature, is in maintenance and may get deprecated in near future. So,
no need to add more code.
BTW this has been discussed previously [1] but there weren't irq users of
eventfd_signal() at the time.

Subject: selftests/vm: use kselftest skip code for skipped tests
There are several test cases in the vm directory are still using exit 0
when they need to be skipped. Use the kselftest framework to skip code
instead so it can help us to distinguish the return status.
Criterion to filter out what should be fixed in vm directory:
grep -r "exit 0" -B1 | grep -i skip
This change might cause some false-positives if people are running these
test scripts directly and only checking their return codes, which will
change from 0 to 4. However I think the impact should be small as most of
our scripts here are already using this skip code. And there will be no
such issue if running them with the kselftest framework.

Subject: lazy tlb: introduce lazy mm refcount helper functions
Patch series "shoot lazy tlbs", v4.
On a 16-socket 192-core POWER8 system, a context switching benchmark with
as many software threads as CPUs (so each switch will go in and out of
idle), upstream can achieve a rate of about 1 million context switches per
second. After this series it goes up to 118 million.
This patch (of 4):
Add explicit _lazy_tlb annotated functions for lazy mm refcounting. This
makes lazy mm references more obvious, and allows explicit refcounting to
be removed if it is not used.
If a kernel thread's current lazy tlb mm happens to be the one it wants to
use, then kthread_use_mm() cleverly transfers the mm refcount from the
lazy tlb mm reference to the returned reference. If the lazy tlb mm
reference is no longer identical to a normal reference, this trick does
not work, so that is changed to be explicit about the two references.

Subject: lazy tlb: allow lazy tlb mm refcounting to be configurable
Add CONFIG_MMU_TLB_REFCOUNT which enables refcounting of the lazy tlb mm
when it is context switched. This can be disabled by architectures that
don't require this refcounting if they clean up lazy tlb mms when the last
refcount is dropped. Currently this is always enabled, which is what
existing code does, so the patch is effectively a no-op.
Rename rq->prev_mm to rq->prev_lazy_mm, because that's what it is.

Subject: lazy tlb: shoot lazies, a non-refcounting lazy tlb option
On big systems, the mm refcount can become highly contented when doing a
lot of context switching with threaded applications (particularly
switching between the idle thread and an application thread).
Abandoning lazy tlb slows switching down quite a bit in the important
user->idle->user cases, so instead implement a non-refcounted scheme that
causes __mmdrop() to IPI all CPUs in the mm_cpumask and shoot down any
remaining lazy ones.
Shootdown IPIs are some concern, but they have not been observed to be a
big problem with this scheme (the powerpc implementation generated 314
additional interrupts on a 144 CPU system during a kernel compile). There
are a number of strategies that could be employed to reduce IPIs if they
turn out to be a problem for some workload.

Subject: powerpc/64s: enable MMU_LAZY_TLB_SHOOTDOWN
On a 16-socket 192-core POWER8 system, a context switching benchmark
with as many software threads as CPUs (so each switch will go in and
out of idle), upstream can achieve a rate of about 1 million context
switches per second. After this patch it goes up to 118 million.
No real datya for real world workloads unfortunately. I think it's
always been a "known" cacheline, it just showed up badly on
will-it-scale tests recently when Anton was doing a sweep of low
hanging scalability issues on big systems.
We have some very big systems running certain in-memory databases that
get into very high contention conditions on mutexes that push context
switch rates right up and with idle times pretty high, which would get
a lot of parallel context switching between user and idle thread, we
might be getting a bit of this contention there.
It's not something at the top of profiles though. And on
multi-threaded workloads like this, the normal refcounting of the user
mm still has fundmaental contention. It's tricky to get the change
tested on these workloads (machine time is very limited and I can't
drive the software).
I suspect it could also show in things that do high net or disk IO
rates (enough to need a lot of cores), and do some user processing
steps along the way. You'd potentially get a lot of idle switching.
This infrastructure could be beneficial to other architectures. The
cacheline is going to bounce in the same situations on other archs, so
I would say yes. Rik at one stage had some patches to try avoid it for
x86 some years ago, I don't know what happened to those.
The way powerpc has to maintain mm_cpumask for its TLB flushing makes
it relatively easy to do this shootdown, and we decided the additional
IPIs were less of a concern than the bouncing. Others have different
concerns, but I tried to make it generic and add comments explaining
what other archs can do, or possibly different ways it might be
achieved.

Subject: mmc: JZ4740: remove the flush_kernel_dcache_page call in jz4740_mmc_read_data
Patch series "_kernel_dcache_page fixes and removal".
While looking to convert the block layer away from kmap_atomic towards
kmap_local_page and prefeably the helpers that abstract it away I noticed
that a few block drivers directly or implicitly call
flush_kernel_dcache_page before kunmapping a page that has been written
to.
flush_kernel_dcache_page is documented to to be used in such cases, but
flush_dcache_page is actually required when the page could be in the page
cache and mapped to userspace, which is pretty much always the case when
kmapping an arbitrary page. Unfortunately the documentation doesn't
exactly make that clear, which lead to this misused. And it turns out
that only the copy_strings / copy_string_kernel in the exec code were
actually correct users of flush_kernel_dcache_page, which is why I think
we should just remove it and eat the very minor overhead in exec rather
than confusing poor driver writers.
This patch (of 6):
MIPS now implements flush_kernel_dcache_page (as an alias to
flush_dcache_page).

Also remove the PageSlab check given that page_mapping_file as used by the

Subject: mm: remove flush_kernel_dcache_page
flush_kernel_dcache_page is a rather confusing interface that implements a
subset of flush_dcache_page by not being able to properly handle page
cache mapped pages.
The only callers left are in the exec code as all other previous callers
were incorrect as they could have dealt with page cache pages. Replace
the calls to flush_kernel_dcache_page with calls to flush_dcache_page,
which for all architectures does either exactly the same thing, can
contains one or more of the following:
1) an optimization to defer the cache flush for page cache pages not
mapped into userspace
2) additional flushing for mapped page cache pages if cache aliases
are possible

From: Huang Ying <ying.huang@intel.com>
Subject: mm,do_huge_pmd_numa_page: remove unnecessary TLB flushing code
Before commit c5b5a3dd2c1f ("mm: thp: refactor NUMA fault handling"), the
TLB flushing is done in do_huge_pmd_numa_page() itself via
flush_tlb_range().
But after commit c5b5a3dd2c1f ("mm: thp: refactor NUMA fault handling"),
the TLB flushing is done in migrate_pages() as in the following code path
anyway.
do_huge_pmd_numa_page
migrate_misplaced_page
migrate_pages
So now, the TLB flushing code in do_huge_pmd_numa_page() becomes
unnecessary. So the code is deleted in this patch to simplify the code.
This is only code cleanup, there's no visible performance difference.
The mmu_notifier_invalidate_range() in do_huge_pmd_numa_page() is
deleted too. Because migrate_pages() takes care of that too when CPU
TLB is flushed.

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Subject: mm: change fault_in_pages_* to have an unsigned size parameter
fault_in_pages_writeable() and fault_in_pages_readable() treat the size
parameter as unsigned, doing pointer math with the value, so make this
explicit and set it to be a size_t type which all callers currently treat
it as anyway.
This solves the issue where static checkers get nervous seeing pointer
arithmetic happening with a signed value.

Subject: mm/pagemap: add mmap_assert_locked() annotations to find_vma*()
find_vma() and variants need protection when used. This patch adds
mmap_assert_lock() calls in the functions.
To make sure the invariant is satisfied, we also need to add a
mmap_read_loc() around the get_user_pages_remote() call in get_arg_page().
The lock is not strictly necessary because the mm has been newly created,
but the extra cost is limited because the same mutex was also acquired
shortly before in __bprm_mm_init(), so it is hot and uncontended.
[penguin-kernel@i-love.sakura.ne.jp: TOMOYO needs the same protection which get_arg_page() needs]

From: Chen Wandun <chenwandun@huawei.com>
Subject: mm/mremap: fix memory account on do_munmap() failure
mremap will account the delta between new_len and old_len in
vma_to_resize, and then call move_vma when expanding an existing memory
mapping. In function move_vma, there are two scenarios when calling
do_munmap:
1. move_page_tables from old_addr to new_addr success
2. move_page_tables from old_addr to new_addr fail
In first scenario, it should account old_len if do_munmap fail, because
the delta has already been accounted.
In second scenario, new_addr/new_len will assign to old_addr/old_len if
move_page_table fail, so do_munmap is try to unmap new_addr actually, if
do_munmap fail, it should account the new_len, because error code will be
return from move_vma, and delta will be unaccounted. What'more, because
of new_len == old_len, so account old_len also is OK.
In summary, account old_len will be correct if do_munmap fail.

Subject: mm: sparse: pass section_nr to section_mark_present
Patch series "mm: sparse: remove __section_nr() function", v4.
This patch (of 3):
With CONFIG_SPARSEMEM_EXTREME enabled, __section_nr() which converts
mem_section to section_nr could be costly since it iterates all section
roots to check if the given mem_section is in its range.
Since both callers of section_mark_present already know section_nr, let's
also pass section_nr as well as mem_section in order to reduce costly
translation.

Subject: mm/sparse: set SECTION_NID_SHIFT to 6
Currently SECTION_NID_SHIFT is set to 3, which is incorrect because bit 3
and 4 can be overlapped by sub-field for early NID, and can be
unexpectedly set on NUMA systems. There are a few non-critical issues
related to this:
- Having SECTION_TAINT_ZONE_DEVICE set for wrong sections forces
pfn_to_online_page() through the slow path, but doesn't actually break
the kernel.
- A kdump generation tool like makedumpfile uses this field to calculate
the physical address to read. So wrong bits can make the tool access to
wrong address and fail to create kdump. This can be avoided by the
tool, so it's not critical.
To fix it, set SECTION_NID_SHIFT to 6 which is the minimum number of
available bits of section flag field.

Subject: include/linux/mmzone.h: avoid a warning in sparse memory support
cppcheck warns that we're possibly losing information by shifting an int.
It's a false positive, because we don't allow for a NUMA node ID that
large, but if we ever change SECTION_NID_SHIFT, it could become a problem,
and in any case this is usually a legitimate warning. Fix it by adding
the necessary cast, which makes the compiler generate the right code.

From: Miles Chen <miles.chen@mediatek.com>
Subject: mm/sparse: clarify pgdat_to_phys
Clarify pgdat_to_phys() by testing if
pgdat == &contig_page_data when CONFIG_NUMA=n.
We only expect contig_page_data in such case, so we
use &contig_page_data directly instead of pgdat.
No functional change intended when CONFIG_BUG_VM=n.
Comment from Mark [1]:
"
... and I reckon it'd be clearer and more robust to define
pgdat_to_phys() in the same ifdefs as contig_page_data so
that these, stay in-sync. e.g. have:
| #ifdef CONFIG_NUMA
| #define pgdat_to_phys(x) virt_to_phys(x)
| #else /* CONFIG_NUMA */
|
| extern struct pglist_data contig_page_data;
| ...
| #define pgdat_to_phys(x) __pa_symbol(&contig_page_data)
|
| #endif /* CONIFIG_NUMA */

To address this issue invoke a bulk-allocator many times until all pages
are obtained, i.e. do batched page requests adding cond_resched()
meanwhile to reschedule. Batched value is hard-coded and is 100 pages per

Get rid of gfpflags_allow_blocking() check from the vmalloc() path as it
is supposed to be sleepable anyway. Thus remove it from the
alloc_vmap_area() as well as from the vm_area_alloc_pages().

Subject: mm/vmalloc: fix wrong behavior in vread
commit f608788cd2d6 ("mm/vmalloc: use rb_tree instead of list for vread()
lookups") use rb_tree instread of list to speed up lookup, but function
__find_vmap_area is try to find a vmap_area that include target address,
if target address is smaller than the leftmost node in vmap_area_root, it
will return NULL, then vread will read nothing. This behavior is
different from the primitive semantics.
The correct way is find the first vmap_are that bigger than target addr,
that is what function find_vmap_area_exceed_addr does.

Move the boot parameter 'kasan.fault' from hw_tags.c to report.c, so it
can support all KASAN modes - generic, and both tag-based.

Subject: kasan: test: rework kmalloc_oob_right
Patch series "kasan: test: avoid crashing the kernel with HW_TAGS", v2.
KASAN tests do out-of-bounds and use-after-free accesses. Running the
tests works fine for the GENERIC mode, as it uses qurantine and redzones.
But the HW_TAGS mode uses neither, and running the tests might crash the
kernel.
Rework the tests to avoid corrupting kernel memory.
This patch (of 8):
Rework kmalloc_oob_right() to do these bad access checks:
1. An unaligned access one byte past the requested kmalloc size
(can only be detected by KASAN_GENERIC).
2. An aligned access into the first out-of-bounds granule that falls
within the aligned kmalloc object.
3. Out-of-bounds access past the aligned kmalloc object.
Test #3 deliberately uses a read access to avoid corrupting memory.
Otherwise, this test might lead to crashes with the HW_TAGS mode, as it
neither uses quarantine nor redzones.

Multiple KASAN tests do writes past the allocated objects or writes to
freed memory. Turn these writes into reads to avoid corrupting memory.
Otherwise, these tests might lead to crashes with the HW_TAGS mode, as it
neither uses quarantine nor redzones.

Subject: kasan: test: avoid corrupting memory via memset
kmalloc_oob_memset_*() tests do writes past the allocated objects. As the
result, they corrupt memory, which might lead to crashes with the HW_TAGS
mode, as it neither uses quarantine nor redzones.
Adjust the tests to only write memory within the aligned kmalloc objects.
Also add a comment mentioning that memset tests are designed to touch both
valid and invalid memory.

The HW_TAGS mode doesn't check memmove for negative size. As a result,
the kmalloc_memmove_invalid_size test corrupts memory, which can result in
a crash.
Disable this test with HW_TAGS KASAN.

kmalloc_uaf_memset() writes to freed memory, which is only safe with the
GENERIC mode (as it uses quarantine). For other modes, this test corrupts
kernel memory, which might result in a crash.
Only enable kmalloc_uaf_memset() for the GENERIC mode.

Subject: kasan: test: clean up ksize_uaf
Some KASAN tests use global variables to store function returns values so
that the compiler doesn't optimize away these functions.
ksize_uaf() doesn't call any functions, so it doesn't need to use
kasan_int_result. Use volatile accesses instead, to be consistent with
other similar tests.

Subject: kasan: test: avoid corrupting memory in copy_user_test
copy_user_test() does writes past the allocated object. As the result, it
corrupts kernel memory, which might lead to crashes with the HW_TAGS mode,
as it neither uses quarantine nor redzones.
(Technically, this test can't yet be enabled with the HW_TAGS mode, but
this will be implemented in the future.)
Adjust the test to only write memory within the aligned kmalloc object.

Subject: mm/page_alloc: always initialize memory map for the holes
Patch series "mm: ensure consistency of memory map poisoning".
Currently memory map allocation for FLATMEM case does not poison the
struct pages regardless of CONFIG_PAGE_POISON setting.
This happens because allocation of the memory map for FLATMEM and SPARSMEM
use different memblock functions and those that are used for SPARSMEM case
(namely memblock_alloc_try_nid_raw() and memblock_alloc_exact_nid_raw())
implicitly poison the allocated memory.
Another side effect of this implicit poisoning is that early setup code
that uses the same functions to allocate memory burns cycles for the
memory poisoning even if it was not intended.
These patches introduce memmap_alloc() wrapper that ensure that the memory
map allocation is consistent for different memory models.
This patch (of 4):
Currently memory map for the holes is initialized only when SPARSEMEM
memory model is used. Yet, even with FLATMEM there could be holes in the
physical memory layout that have memory map entries.
For instance, the memory reserved using e820 API on i386 or
"reserved-memory" nodes in device tree would not appear in memblock.memory
and hence the struct pages for such holes will be skipped during memory
map initialization.
These struct pages will be zeroed because the memory map for FLATMEM
systems is allocated with memblock_alloc_node() that clears the allocated
memory. While zeroed struct pages do not cause immediate problems, the
correct behaviour is to initialize every page using __init_single_page().
Besides, enabling page poison for FLATMEM case will trigger
PF_POISONED_CHECK() unless the memory map is properly initialized.
Make sure init_unavailable_range() is called for both SPARSEMEM and
FLATMEM so that struct pages representing memory holes would appear as
PG_Reserved with any memory layout.

Subject: microblaze: simplify pte_alloc_one_kernel()
The microblaze's implementation of pte_alloc_one_kernel() used
memblock_alloc_try_nid_raw() along with clear_page() to allocated a zeroed
page during early setup.
Replace calls of these functions with a call to memblock_alloc_try_nid()
that already returns zeroed page and respects the same allocation limits
as memblock_alloc_try_nid_raw().
While on it drop early_get_page() wrapper that was only used in
pte_alloc_one_kernel().

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: introduce memmap_alloc() to unify memory map allocation
There are several places that allocate memory for the memory map:
alloc_node_mem_map() for FLATMEM, sparse_buffer_init() and
__populate_section_memmap() for SPARSEMEM.
The memory allocated in the FLATMEM case is zeroed and it is never
poisoned, regardless of CONFIG_PAGE_POISON setting.
The memory allocated in the SPARSEMEM cases is not zeroed and it is
implicitly poisoned inside memblock if CONFIG_PAGE_POISON is set.
Introduce memmap_alloc() wrapper for memblock allocators that will be used
for both FLATMEM and SPARSEMEM cases and will makei memory map zeroing and
poisoning consistent for different memory models.

Subject: memblock: stop poisoning raw allocations
Functions memblock_alloc_exact_nid_raw() and memblock_alloc_try_nid_raw()
are intended for early memory allocation without overhead of zeroing the
allocated memory. Since these functions were used to allocate the memory
map, they have ended up with addition of a call to page_init_poison() that
poisoned the allocated memory when CONFIG_PAGE_POISON was set.
Since the memory map is allocated using a dedicated memmep_alloc()
function that takes care of the poisoning, remove page poisoning from the
memblock_alloc_*_raw() functions.

Subject: mm/page_alloc.c: fix 'zone_id' may be used uninitialized in this function warning
When compiling with -Werror, cc1 will warn that 'zone_id' may be used
uninitialized in this function warning.
Initialize the zone_id as 0.
Its safe to assume that if the code reaches this point it has at least one
numa node with memory, so no need for an assertion before
init_unavilable_range.

alloc_node_mem_map() is never only called from free_area_init_node() that
is an __init function.
Make the actual alloc_node_mem_map() also __init and its stub version
static inline.

Subject: mm/page_isolation: tracing: trace all test_pages_isolated failures
Some test_pages_isolated failure conditions don't include trace points.
For debugging issues caused by "pinned" pages, make sure to trace all
calls whether they succeed or fail. In this case, a failure case did not
result in a trace point. So add the missing failure case in
test_pages_isolated traces.

Patch series "Cleanups and fixup for hwpoison"
This series contains cleanups to remove unneeded variable, fix some
obsolete comments and so on. Also we fix potential pte_unmap_unlock on
wrong pte. More details can be found in the respective changelogs.
This patch (of 4):
unmap_success is used to indicate whether page is successfully unmapped
but it's irrelated with ZONE_DEVICE page and unmap_success is always true
here. Remove this unneeded one.

shrink_node_slabs is renamed to drop_slab_node. And doit argument is
changed to forcekill since commit 6751ed65dc66 ("x86/mce: Fix
siginfo_t->si_addr value for non-recoverable memory faults").

Subject: mm: hwpoison: don't drop slab caches for offlining non-LRU page
In the current implementation of soft offline, if non-LRU page is met, all
the slab caches will be dropped to free the page then offline. But if the
page is not slab page all the effort is wasted in vain. Even though it is
a slab page, it is not guaranteed the page could be freed at all.
However the side effect and cost is quite high. It does not only drop the
slab caches, but also may drop a significant amount of page caches which
are associated with inode caches. It could make the most workingset gone
in order to just offline a page. And the offline is not guaranteed to
succeed at all, actually I really doubt the success rate for real life
workload.
Furthermore the worse consequence is the system may be locked up and
unusable since the page cache release may incur huge amount of works
queued for memcg release.
Actually we ran into such unpleasant case in our production environment.
Firstly, the workqueue of memory_failure_work_func is locked up as below:
BUG: workqueue lockup - pool cpus=1 node=0 flags=0x0 nice=0 stuck for 53s!
Showing busy workqueues and worker pools:
workqueue events: flags=0x0

pending: css_release_work_fn
There were over 12K css_release_work_fn queued, and this caused a few
lockups due to the contention of worker pool lock with IRQ disabled, for
example:

The lockup made the machine is quite unusable. And it also made the most
workingset gone, the reclaimabled slab caches were reduced from 12G to
300MB, the page caches were decreased from 17G to 4G.
But the most disappointing thing is all the effort doesn't make the page
offline, it just returns:
soft_offline: 0x1469f2: unknown non LRU page type 5ffff0000000000 ()
It seems the aggressive behavior for non-LRU page didn't pay back, so it
doesn't make too much sense to keep it considering the terrible side
effect.

Subject: mm: hwpoison: dump page for unhandlable page
Currently just very simple message is shown for unhandlable page, e.g.
non-LRU page, like: soft_offline: 0x1469f2: unknown non LRU page type
5ffff0000000000 ()
It is not very helpful for further debug, calling dump_page() could show
more useful information.
Calling dump_page() in get_any_page() in order to not duplicate the call
in a couple of different places. It may be called with pcp disabled and
holding memory hotplug lock, it should be not a big deal since hwpoison
handler is not called very often.

Subject: mm: fix panic caused by __page_handle_poison()
In commit 510d25c92ec4 ("mm/hwpoison: disable pcp for
page_handle_poison()"), __page_handle_poison() was introduced, and if we
mark:
RET_A = dissolve_free_huge_page();
RET_B = take_page_off_buddy();
then __page_handle_poison was supposed to return TRUE When RET_A == 0 &&
RET_B == TRUE
But since it failed to take care the case when RET_A is -EBUSY or -ENOMEM,
and just return the ret as a bool which actually become TRUE, it break the
original logic.
The following result is a huge page in freelist but was
referenced as poisoned, and lead into the final panic:

Subject: hugetlb: simplify prep_compound_gigantic_page ref count racing code
Code in prep_compound_gigantic_page waits for a rcu grace period if it
notices a temporarily inflated ref count on a tail page. This was due to
the identified potential race with speculative page cache references which
could only last for a rcu grace period. This is overly complicated as
this situation is VERY unlikely to ever happen. Instead, just quickly
return an error.
Also, only print a warning in prep_compound_gigantic_page instead of
multiple callers.

Subject: hugetlb: drop ref count earlier after page allocation
When discussing the possibility of inflated page ref counts, Muuchun Song
pointed out this potential issue [1]. It is true that any code could
potentially take a reference on a compound page after allocation and
before it is converted to and put into use as a hugetlb page.
Specifically, this could be done by any users of get_page_unless_zero.
There are three areas of concern within hugetlb code.
1) When adding pages to the pool. In this case, new pages are
allocated added to the pool by calling put_page to invoke the hugetlb
destructor (free_huge_page). If there is an inflated ref count on the
page, it will not be immediately added to the free list. It will only
be added to the free list when the temporary ref count is dropped.
This is deemed acceptable and will not be addressed.
2) A page is allocated for immediate use normally as a surplus page or
migration target. In this case, the user of the page will also hold a
reference. There is no issue as this is just like normal page ref
counting.
3) A page is allocated and MUST be added to the free list to satisfy a
reservation. One such example is gather_surplus_pages as pointed out
by Muchun in [1]. More specifically, this case covers callers of
enqueue_huge_page where the page reference count must be zero. This
patch covers this third case.
Three routines call enqueue_huge_page when the page reference count could
potentially be inflated. They are: gather_surplus_pages,
alloc_and_dissolve_huge_page and add_hugetlb_page.
add_hugetlb_page is called on error paths when a huge page can not be
freed due to the inability to allocate vmemmap pages. In this case, the
temporairly inflated ref count is not an issue. When the ref is dropped
the appropriate action will be taken. Instead of VM_BUG_ON if the ref
count does not drop to zero, simply return.
In gather_surplus_pages and alloc_and_dissolve_huge_page the caller
expects a page (or pages) to be put on the free lists. In this case we
must ensure there are no temporary ref counts. We do this by calling
put_page_testzero() earlier and not using pages without a zero ref count.
The temporary page flag (HPageTemporary) is used in such cases so that as
soon as the inflated ref count is dropped the page will be freed.

Subject: hugetlb: before freeing hugetlb page set dtor to appropriate value
When removing a hugetlb page from the pool the ref count is set to one (as
the free page has no ref count) and compound page destructor is set to
NULL_COMPOUND_DTOR. Since a subsequent call to free the hugetlb page will
call __free_pages for non-gigantic pages and free_gigantic_page for
gigantic pages the destructor is not used.
However, consider the following race with code taking a speculative
reference on the page:
Thread 0 Thread 1
-------- --------
remove_hugetlb_page
set_page_refcounted(page);
set_compound_page_dtor(page,
NULL_COMPOUND_DTOR);
get_page_unless_zero(page)
__update_and_free_page
__free_pages(page,
huge_page_order(h));
/* Note that __free_pages() will simply drop
the reference to the page. */
put_page(page)
__put_compound_page()
destroy_compound_page
NULL_COMPOUND_DTOR
BUG: kernel NULL pointer
dereference, address:
0000000000000000
To address this race, set the dtor to the normal compound page dtor for
non-gigantic pages. The dtor for gigantic pages does not matter as
gigantic pages are changed from a compound page to 'just a group of pages'
before freeing. Hence, the destructor is not used.

Upon further examination, it was discovered that the css structure was
associated with hugetlb reservations.
For private hugetlb mappings the vma points to a reserve map that contains
a pointer to the css. At mmap time, reservations are set up and a
reference to the css is taken. This reference is dropped in the vma close
operation; hugetlb_vm_op_close. However, if a vma is split no additional
reference to the css is taken yet hugetlb_vm_op_close will be called twice
for the split vma resulting in an underflow.
Fix by taking another reference in hugetlb_vm_op_open. Note that the
reference is only taken for the owner of the reserve map. In the more
common fork case, the pointer to the reserve map is cleared for non-owning
vmas.

Subject: userfaultfd: change mmap_changing to atomic
Patch series "userfaultfd: minor bug fixes".
Three unrelated bug fixes. The first two addresses possible issues (not
too theoretical ones), but I did not encounter them in practice.
The third patch addresses a test bug that causes the test to fail on my
system. It has been sent before as part of a bigger RFC.
This patch (of 3):
mmap_changing is currently a boolean variable, which is set and cleared
without any lock that protects against concurrent modifications.
mmap_changing is supposed to mark whether userfaultfd page-faults handling
should be retried since mappings are undergoing a change. However,
concurrent calls, for instance to madvise(MADV_DONTNEED), might cause
mmap_changing to be false, although the remove event was still not read
(hence acknowledged) by the user.
Change mmap_changing to atomic_t and increase/decrease appropriately. Add
a debug assertion to see whether mmap_changing is negative.

Subject: userfaultfd: prevent concurrent API initialization
userfaultfd assumes that the enabled features are set once and never
changed after UFFDIO_API ioctl succeeded.
However, currently, UFFDIO_API can be called concurrently from two
different threads, succeed on both threads and leave userfaultfd's
features in non-deterministic state. Theoretically, other uffd operations
(ioctl's and page-faults) can be dispatched while adversely affected by
such changes of features.
Moreover, the writes to ctx->state and ctx->features are not ordered,
which can - theoretically, again - let userfaultfd_ioctl() think that
userfaultfd API completed, while the features are still not initialized.
To avoid races, it is arguably best to get rid of ctx->state. Since there
are only 2 states, record the API initialization in ctx->features as the
uppermost bit and remove ctx->state.

Subject: selftests/vm/userfaultfd: wake after copy failure
When userfaultfd copy-ioctl fails since the PTE already exists, an -EEXIST
error is returned and the faulting thread is not woken. The current
userfaultfd test does not wake the faulting thread in such case. The
assumption is presumably that another thread set the PTE through copy/wp
ioctl and would wake the faulting thread or that alternatively the fault
handler would realize there is no need to "must_wait" and continue. This
is not necessarily true.
There is an assumption that the "must_wait" tests in handle_userfault()
are sufficient to provide definitive answer whether the offending PTE is
populated or not. However, userfaultfd_must_wait() test is lockless.
Consequently, concurrent calls to ptep_modify_prot_start(), for instance,
can clear the PTE and can cause userfaultfd_must_wait() to wrongly assume
it is not populated and a wait is needed.
There are therefore 3 options:
(1) Change the tests to wake on copy failure.
(2) Wake faulting thread unconditionally on zero/copy ioctls before
returning -EEXIST.
(3) Change the userfaultfd_must_wait() to hold locks.
This patch took the first approach, but the others are valid solutions
with different tradeoffs.

Subject: mm/numa: automatically generate node migration order
Patch series "Migrate Pages in lieu of discard", v11.
We're starting to see systems with more and more kinds of memory such as
Intel's implementation of persistent memory.
Let's say you have a system with some DRAM and some persistent memory.
Today, once DRAM fills up, reclaim will start and some of the DRAM
contents will be thrown out. Allocations will, at some point, start
falling over to the slower persistent memory.
That has two nasty properties. First, the newer allocations can end up in
the slower persistent memory. Second, reclaimed data in DRAM are just
discarded even if there are gobs of space in persistent memory that could
be used.
This patchset implements a solution to these problems. At the end of the
reclaim process in shrink_page_list() just before the last page refcount
is dropped, the page is migrated to persistent memory instead of being
dropped.
While I've talked about a DRAM/PMEM pairing, this approach would function
in any environment where memory tiers exist.
This is not perfect. It "strands" pages in slower memory and never brings
them back to fast DRAM. Huang Ying has follow-on work which repurposes
NUMA balancing to promote hot pages back to DRAM.
This is also all based on an upstream mechanism that allows persistent
memory to be onlined and used as if it were volatile:
http://lkml.kernel.org/r/20190124231441.37A4A305@viggo.jf.intel.com
With that, the DRAM and PMEM in each socket will be represented as 2
separate NUMA nodes, with the CPUs sit in the DRAM node. So the
general inter-NUMA demotion mechanism introduced in the patchset can
migrate the cold DRAM pages to the PMEM node.
We have tested the patchset with the postgresql and pgbench. On a
2-socket server machine with DRAM and PMEM, the kernel with the patchset
can improve the score of pgbench up to 22.1% compared with that of the
DRAM only + disk case. This comes from the reduced disk read throughput
(which reduces up to 70.8%).
== Open Issues ==
* Memory policies and cpusets that, for instance, restrict allocations
to DRAM can be demoted to PMEM whenever they opt in to this
new mechanism. A cgroup-level API to opt-in or opt-out of
these migrations will likely be required as a follow-on.
* Could be more aggressive about where anon LRU scanning occurs
since it no longer necessarily involves I/O. get_scan_count()
for instance says: "If we have no swap space, do not bother
scanning anon pages"
This patch (of 9):
Prepare for the kernel to auto-migrate pages to other memory nodes with a
node migration table. This allows creating single migration target for
each NUMA node to enable the kernel to do NUMA page migrations instead of
simply discarding colder pages. A node with no target is a "terminal
node", so reclaim acts normally there. The migration target does not
fundamentally _need_ to be a single node, but this implementation starts
there to limit complexity.
When memory fills up on a node, memory contents can be automatically
migrated to another node. The biggest problems are knowing when to
migrate and to where the migration should be targeted.
The most straightforward way to generate the "to where" list would be to
follow the page allocator fallback lists. Those lists already tell us if
memory is full where to look next. It would also be logical to move
memory in that order.
But, the allocator fallback lists have a fatal flaw: most nodes appear in
all the lists. This would potentially lead to migration cycles (A->B,
B->A, A->B, ...).
Instead of using the allocator fallback lists directly, keep a separate
node migration ordering. But, reuse the same data used to generate page
allocator fallback in the first place: find_next_best_node().
This means that the firmware data used to populate node distances
essentially dictates the ordering for now. It should also be
architecture-neutral since all NUMA architectures have a working
find_next_best_node().
RCU is used to allow lock-less read of node_demotion[] and prevent
demotion cycles been observed. If multiple reads of node_demotion[] are
performed, a single rcu_read_lock() must be held over all reads to ensure
no cycles are observed. Details are as follows.
=== What does RCU provide? ===
Imagine a simple loop which walks down the demotion path looking
for the last node:
terminal_node = start_node;
while (node_demotion[terminal_node] != NUMA_NO_NODE) {
terminal_node = node_demotion[terminal_node];
}
The initial values are:
node_demotion[0] = 1;
node_demotion[1] = NUMA_NO_NODE;
and are updated to:
node_demotion[0] = NUMA_NO_NODE;
node_demotion[1] = 0;
What guarantees that the cycle is not observed:
node_demotion[0] = 1;
node_demotion[1] = 0;
and would loop forever?
With RCU, a rcu_read_lock/unlock() can be placed around the loop. Since
the write side does a synchronize_rcu(), the loop that observed the old
contents is known to be complete before the synchronize_rcu() has
completed.
RCU, combined with disable_all_migrate_targets(), ensures that the old
migration state is not visible by the time __set_migration_target_nodes()
is called.
=== What does READ_ONCE() provide? ===
READ_ONCE() forbids the compiler from merging or reordering successive
reads of node_demotion[]. This ensures that any updates are *eventually*
observed.
Consider the above loop again. The compiler could theoretically read the
entirety of node_demotion[] into local storage (registers) and never go
back to memory, and *permanently* observe bad values for node_demotion[].
Note: RCU does not provide any universal compiler-ordering

Subject: mm/migrate: update node demotion order on hotplug events
Reclaim-based migration is attempting to optimize data placement in memory
based on the system topology. If the system changes, so must the
migration ordering.
The implementation is conceptually simple and entirely unoptimized. On
any memory or CPU hotplug events, assume that a node was added or removed
and recalculate all migration targets. This ensures that the
node_demotion[] array is always ready to be used in case the new reclaim
mode is enabled.
This recalculation is far from optimal, most glaringly that it does not
even attempt to figure out the hotplug event would have some *actual*
effect on the demotion order. But, given the expected paucity of hotplug
events, this should be fine.

From: Yang Shi <yang.shi@linux.alibaba.com>
Subject: mm/migrate: enable returning precise migrate_pages() success count
Under normal circumstances, migrate_pages() returns the number of pages
migrated. In error conditions, it returns an error code. When returning
an error code, there is no way to know how many pages were migrated or not
migrated.
Make migrate_pages() return how many pages are demoted successfully for
all cases, including when encountering errors. Page reclaim behavior will
depend on this in subsequent patches.

From: Dave Hansen <dave.hansen@linux.intel.com>
Subject: mm/migrate: demote pages during reclaim
This is mostly derived from a patch from Yang Shi:
https://lore.kernel.org/linux-mm/1560468577-101178-10-git-send-email-yang.shi@linux.alibaba.com/
Add code to the reclaim path (shrink_page_list()) to "demote" data to
another NUMA node instead of discarding the data. This always avoids the
cost of I/O needed to read the page back in and sometimes avoids the
writeout cost when the page is dirty.
A second pass through shrink_page_list() will be made if any demotions
fail. This essentially falls back to normal reclaim behavior in the case
that demotions fail. Previous versions of this patch may have simply
failed to reclaim pages which were eligible for demotion but were unable
to be demoted in practice.
For some cases, for example, MADV_PAGEOUT, the pages are always discarded
instead of demoted to follow the kernel API definition. Because
MADV_PAGEOUT is defined as freeing specified pages regardless in which
tier they are.
Note: This just adds the start of infrastructure for migration. It is
actually disabled next to the FIXME in migrate_demote_page_ok().

Subject: mm/vmscan: add helper for querying ability to age anonymous pages
Anonymous pages are kept on their own LRU(s). These lists could
theoretically always be scanned and maintained. But, without swap, there
is currently nothing the kernel can *do* with the results of a scanned,
sorted LRU for anonymous pages.
A check for '!total_swap_pages' currently serves as a valid check as to
whether anonymous LRUs should be maintained. However, another method will
be added shortly: page demotion.
Abstract out the 'total_swap_pages' checks into a helper, give it a
logically significant name, and check for the possibility of page
demotion.

Subject: mm/vmscan: Consider anonymous pages without swap
Reclaim anonymous pages if a migration path is available now that demotion
provides a non-swap recourse for reclaiming anon pages.
Note that this check is subtly different from the can_age_anon_pages()
checks. This mechanism checks whether a specific page in a specific
context can actually be reclaimed, given current swap space and cgroup
limits.
can_age_anon_pages() is a much simpler and more preliminary check which
just says whether there is a possibility of future reclaim.

Subject: mm/vmscan: never demote for memcg reclaim
Global reclaim aims to reduce the amount of memory used on a given node or
set of nodes. Migrating pages to another node serves this purpose.
memcg reclaim is different. Its goal is to reduce the total memory
consumption of the entire memcg, across all nodes. Migration does not
assist memcg reclaim because it just moves page contents between nodes
rather than actually reducing memory consumption.

Subject: mm/migrate: add sysfs interface to enable reclaim migration
Some method is obviously needed to enable reclaim-based migration.
Just like traditional autonuma, there will be some workloads that will
benefit like workloads with more "static" configurations where hot pages
stay hot and cold pages stay cold. If pages come and go from the hot and
cold sets, the benefits of this approach will be more limited.
The benefits are truly workload-based and *not* hardware-based. We do not
believe that there is a viable threshold where certain hardware
configurations should have this mechanism enabled while others do not.
To be conservative, earlier work defaulted to disable reclaim- based
migration and did not include a mechanism to enable it. This proposes add
a new sysfs file
/sys/kernel/mm/numa/demotion_enabled
as a method to enable it.
We are open to any alternative that allows end users to enable this
mechanism or disable it if workload harm is detected (just like
traditional autonuma).
Once this is enabled page demotion may move data to a NUMA node that does
not fall into the cpuset of the allocating process. This could be
construed to violate the guarantees of cpusets. However, since this is an
opt-in mechanism, the assumption is that anyone enabling it is content to
relax the guarantees.

+Description: Enable/disable demoting pages during reclaim
+
+ Page migration during reclaim is intended for systems
+ with tiered memory configurations. These systems have
+ multiple types of memory with varied performance
+ characteristics instead of plain NUMA systems where
+ the same kind of memory is found at varied distances.
+ Allowing page migration during reclaim enables these
+ systems to migrate pages from fast tiers to slow tiers
+ when the fast tier is under pressure. This migration
+ is performed before swap. It may move data to a NUMA
+ node that does not fall into the cpuset of the
+ allocating process which might be construed to violate
+ the guarantees of cpusets. This should not be enabled
+ on systems which need strict cpuset location
+ guarantees.

We can get memcg directly form vmpr instead of vmpr->memcg->css->memcg, so
add a new func helper vmpressure_to_memcg(). And no code will use
vmpressure_to_css(), so delete it.

Subject: mm/vmscan: remove the PageDirty check after MADV_FREE pages are page_ref_freezed
Patch series "Cleanups for vmscan", v2.
This series contains cleanups to remove unneeded return value, misleading
setting and so on. Also this remove the PageDirty check after MADV_FREE
pages are page_ref_freezed. More details can be found in the respective
changelogs.
This patch (of 4):
If the MADV_FREE pages are redirtied before they could be reclaimed, put
the pages back to anonymous LRU list by setting SwapBacked flag and the
pages will be reclaimed in normal swapout way. But as Yu Zhao pointed
out, "The page has only one reference left, which is from the isolation.
After the caller puts the page back on lru and drops the reference, the
page will be freed anyway. It doesn't matter which lru it goes." So we
don't bother checking PageDirty here.
[Yu Zhao's comment is also quoted in the code.]

The priority field of sc is used to control how many pages we should scan
at once while we always traverse the list to shrink the pages in these
functions. So these settings are unneeded and misleading.

Subject: mm, vmscan: guarantee drop_slab_node() termination
drop_slab_node() is called as part of echo 2>/proc/sys/vm/drop_caches
operation. It iterates over all memcgs and calls shrink_slab() which in
turn iterates over all slab shrinkers. Freed objects are counted and as
long as the total number of freed objects from all memcgs and shrinkers is
higher than 10, drop_slab_node() loops for another full memcgs*shrinkers
iteration.
This arbitrary constant threshold of 10 can result in effectively an
infinite loop on a system with large number of memcgs and/or parallel
activity that allocates new objects. This has been reported previously by
Chunxin Zang [1] and recently by our customer.
The previous report [1] has resulted in commit 069c411de40a ("mm/vmscan:
fix infinite loop in drop_slab_node") which added a check for signals
allowing the user to terminate the command writing to drop_caches. At the
time it was also considered to make the threshold grow with each iteration
to guarantee termination, but such patch hasn't been formally proposed
yet.
This patch implements the dynamically growing threshold. At first
iteration it's enough to free one object to continue, and this threshold
effectively doubles with each iteration. Our customer's feedback was
positive.
There is always a risk that this change will result on some system in a
previously terminating drop_caches operation to terminate sooner and free
fewer objects. Ideally the semantics would guarantee freeing all freeable
objects that existed at the moment of starting the operation, while not
looping forever for newly allocated objects, but that's not feasible to
track. In the less ideal solution based on thresholds, arguably the
termination guarantee is more important than the exhaustiveness guarantee.
If there are reports of large regression wrt being exhaustive, we can
tune how fast the threshold grows.

Subject: mm: compaction: optimize proactive compaction deferrals
Vlastimil Babka figured out that when fragmentation score didn't go down
across the proactive compaction i.e. when no progress is made, next wake
up for proactive compaction is deferred for 1 << COMPACT_MAX_DEFER_SHIFT,
i.e. 64 times, with each wakeup interval of
HPAGE_FRAG_CHECK_INTERVAL_MSEC(=500). In each of this wakeup, it just
decrement 'proactive_defer' counter and goes sleep i.e. it is getting
woken to just decrement a counter.
The same deferral time can also achieved by simply doing the
HPAGE_FRAG_CHECK_INTERVAL_MSEC << COMPACT_MAX_DEFER_SHIFT thus unnecessary
wakeup of kcompact thread is avoided thus also removes the need of
'proactive_defer' thread counter.

Subject: mm: compaction: support triggering of proactive compaction by user
The proactive compaction[1] gets triggered for every 500msec and run
compaction on the node for COMPACTION_HPAGE_ORDER (usually order-9) pages
based on the value set to sysctl.compaction_proactiveness. Triggering the
compaction for every 500msec in search of COMPACTION_HPAGE_ORDER pages is
not needed for all applications, especially on the embedded system
usecases which may have few MB's of RAM. Enabling the proactive
compaction in its state will endup in running almost always on such
systems.
Other side, proactive compaction can still be very much useful for getting
a set of higher order pages in some controllable manner(controlled by
using the sysctl.compaction_proactiveness). So, on systems where enabling
the proactive compaction always may proove not required, can trigger the
same from user space on write to its sysctl interface. As an example, say
app launcher decide to launch the memory heavy application which can be
launched fast if it gets more higher order pages thus launcher can prepare
the system in advance by triggering the proactive compaction from
userspace.
This triggering of proactive compaction is done on a write to
sysctl.compaction_proactiveness by user.

Subject: mm/mempolicy: add MPOL_PREFERRED_MANY for multiple preferred nodes
Patch series "Introduce multi-preference mempolicy", v7.
This patch series introduces the concept of the MPOL_PREFERRED_MANY
mempolicy. This mempolicy mode can be used with either the
set_mempolicy(2) or mbind(2) interfaces. Like the MPOL_PREFERRED
interface, it allows an application to set a preference for nodes which
will fulfil memory allocation requests. Unlike the MPOL_PREFERRED mode,
it takes a set of nodes. Like the MPOL_BIND interface, it works over a
set of nodes. Unlike MPOL_BIND, it will not cause a SIGSEGV or invoke the
OOM killer if those preferred nodes are not available.
Along with these patches are patches for libnuma, numactl, numademo, and
memhog. They still need some polish, but can be found here:
https://gitlab.com/bwidawsk/numactl/-/tree/prefer-many It allows new
usage: `numactl -P 0,3,4`
The goal of the new mode is to enable some use-cases when using tiered memory
usage models which I've lovingly named.
1a. The Hare - The interconnect is fast enough to meet bandwidth and
latency requirements allowing preference to be given to all nodes with
"fast" memory.
1b. The Indiscriminate Hare - An application knows it wants fast
memory (or perhaps slow memory), but doesn't care which node it runs
on. The application can prefer a set of nodes and then xpu bind to
the local node (cpu, accelerator, etc). This reverses the nodes are
chosen today where the kernel attempts to use local memory to the CPU
whenever possible. This will attempt to use the local accelerator to
the memory.
2. The Tortoise - The administrator (or the application itself) is
aware it only needs slow memory, and so can prefer that.
Much of this is almost achievable with the bind interface, but the bind
interface suffers from an inability to fallback to another set of nodes if
binding fails to all nodes in the nodemask.
Like MPOL_BIND a nodemask is given. Inherently this removes ordering from the
preference.
> /* Set first two nodes as preferred in an 8 node system. */
> const unsigned long nodes = 0x3
> set_mempolicy(MPOL_PREFER_MANY, &nodes, 8);
> /* Mimic interleave policy, but have fallback *.
> const unsigned long nodes = 0xaa
> set_mempolicy(MPOL_PREFER_MANY, &nodes, 8);
Some internal discussion took place around the interface. There are two
alternatives which we have discussed, plus one I stuck in:
1. Ordered list of nodes. Currently it's believed that the added
complexity is nod needed for expected usecases.
2. A flag for bind to allow falling back to other nodes. This
confuses the notion of binding and is less flexible than the current
solution.
3. Create flags or new modes that helps with some ordering. This
offers both a friendlier API as well as a solution for more customized
usage. It's unknown if it's worth the complexity to support this.
Here is sample code for how this might work:
> // Prefer specific nodes for some something wacky
> set_mempolicy(MPOL_PREFER_MANY, 0x17c, 1024);
>
> // Default
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_SOCKET, NULL, 0);
> // which is the same as
> set_mempolicy(MPOL_DEFAULT, NULL, 0);
>
> // The Hare
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE, NULL, 0);
>
> // The Tortoise
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE_REV, NULL, 0);
>
> // Prefer the fast memory of the first two sockets
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE, -1, 2);
>
This patch (of 5):
The NUMA APIs currently allow passing in a "preferred node" as a single
bit set in a nodemask. If more than one bit it set, bits after the first
are ignored.
This single node is generally OK for location-based NUMA where memory
being allocated will eventually be operated on by a single CPU. However,
in systems with multiple memory types, folks want to target a *type* of
memory instead of a location. For instance, someone might want some
high-bandwidth memory but do not care about the CPU next to which it is
allocated. Or, they want a cheap, high capacity allocation and want to
target all NUMA nodes which have persistent memory in volatile mode. In
both of these cases, the application wants to target a *set* of nodes, but
does not want strict MPOL_BIND behavior as that could lead to OOM killer
or SIGSEGV.
So add MPOL_PREFERRED_MANY policy to support the multiple preferred nodes
requirement. This is not a pie-in-the-sky dream for an API. This was a
response to a specific ask of more than one group at Intel. Specifically:
1. There are existing libraries that target memory types such as
https://github.com/memkind/memkind. These are known to suffer from
SIGSEGV's when memory is low on targeted memory "kinds" that span more
than one node. The MCDRAM on a Xeon Phi in "Cluster on Die" mode is an
example of this.
2. Volatile-use persistent memory users want to have a memory policy
which is targeted at either "cheap and slow" (PMEM) or "expensive and
fast" (DRAM). However, they do not want to experience allocation
failures when the targeted type is unavailable.
3. Allocate-then-run. Generally, we let the process scheduler decide
on which physical CPU to run a task. That location provides a default
allocation policy, and memory availability is not generally considered
when placing tasks. For situations where memory is valuable and
constrained, some users want to allocate memory first, *then* allocate
close compute resources to the allocation. This is the reverse of the
normal (CPU) model. Accelerators such as GPUs that operate on
core-mm-managed memory are interested in this model.
A check is added in sanitize_mpol_flags() to not permit 'prefer_many'
policy to be used for now, and will be removed in later patch after all
implementations for 'prefer_many' are ready, as suggested by Michal Hocko.

Subject: mm/memplicy: add page allocation function for MPOL_PREFERRED_MANY policy
The semantics of MPOL_PREFERRED_MANY is similar to MPOL_PREFERRED, that it
will first try to allocate memory from the preferred node(s), and fallback
to all nodes in system when first try fails.
Add a dedicated function alloc_pages_preferred_many() for it just like for
'interleave' policy, which will be used by 2 general memoory allocation
APIs: alloc_pages() and alloc_pages_vma()

Subject: mm/hugetlb: add support for mempolicy MPOL_PREFERRED_MANY
Implement the missing huge page allocation functionality while obeying the
preferred node semantics. This is similar to the implementation for
general page allocation, as it uses a fallback mechanism to try multiple
preferred nodes first, and then all other nodes.
To avoid adding too many "#ifdef CONFIG_NUMA" check, add a helper function
in mempolicy.h to check whether a mempolicy is MPOL_PREFERRED_MANY.

Subject: mm/mempolicy: advertise new MPOL_PREFERRED_MANY
Adds a new mode to the existing mempolicy modes, MPOL_PREFERRED_MANY.
MPOL_PREFERRED_MANY will be adequately documented in the internal
admin-guide with this patch. Eventually, the man pages for mbind(2),
get_mempolicy(2), set_mempolicy(2) and numactl(8) will also have text
about this mode. Those shall contain the canonical reference.
NUMA systems continue to become more prevalent. New technologies like
PMEM make finer grain control over memory access patterns increasingly
desirable. MPOL_PREFERRED_MANY allows userspace to specify a set of nodes
that will be tried first when performing allocations. If those
allocations fail, all remaining nodes will be tried. It's a straight
forward API which solves many of the presumptive needs of system
administrators wanting to optimize workloads on such machines. The mode
will work either per VMA, or per thread.

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: memblock: make memblock_find_in_range method private
There are a lot of uses of memblock_find_in_range() along with
memblock_reserve() from the times memblock allocation APIs did not exist.
memblock_find_in_range() is the very core of memblock allocations, so any
future changes to its internal behaviour would mandate updates of all the
users outside memblock.
Replace the calls to memblock_find_in_range() with an equivalent calls to
memblock_phys_alloc() and memblock_phys_alloc_range() and make
memblock_find_in_range() private method of memblock.
This simplifies the callers, ensures that (unlikely) errors in
memblock_reserve() are handled and improves maintainability of
memblock_find_in_range().

From: Suren Baghdasaryan <surenb@google.com>
Subject: mm: introduce process_mrelease system call
In modern systems it's not unusual to have a system component monitoring
memory conditions of the system and tasked with keeping system memory
pressure under control. One way to accomplish that is to kill
non-essential processes to free up memory for more important ones.
Examples of this are Facebook's OOM killer daemon called oomd and
Android's low memory killer daemon called lmkd.
For such system component it's important to be able to free memory quickly
and efficiently. Unfortunately the time process takes to free up its
memory after receiving a SIGKILL might vary based on the state of the
process (uninterruptible sleep), size and OPP level of the core the
process is running. A mechanism to free resources of the target process
in a more predictable way would improve system's ability to control its
memory pressure.
Introduce process_mrelease system call that releases memory of a dying
process from the context of the caller. This way the memory is freed in a
more controllable way with CPU affinity and priority of the caller. The
workload of freeing the memory will also be charged to the caller. The
operation is allowed only on a dying process.
After previous discussions [1, 2, 3] the decision was made [4] to
introduce a dedicated system call to cover this use case.
The API is as follows,
int process_mrelease(int pidfd, unsigned int flags);
DESCRIPTION
The process_mrelease() system call is used to free the memory of
an exiting process.
The pidfd selects the process referred to by the PID file
descriptor.
(See pidfd_open(2) for further information)
The flags argument is reserved for future use; currently, this
argument must be specified as 0.
RETURN VALUE
On success, process_mrelease() returns 0. On error, -1 is
returned and errno is set to indicate the error.
ERRORS
EBADF pidfd is not a valid PID file descriptor.
EAGAIN Failed to release part of the address space.
EINTR The call was interrupted by a signal; see signal(7).
EINVAL flags is not 0.
EINVAL The memory of the task cannot be released because the
process is not exiting, the address space is shared
with another live process or there is a core dump in
progress.
ENOSYS This system call is not supported, for example, without
MMU support built into Linux.
ESRCH The target process does not exist (i.e., it has terminated
and been waited on).

From: Zhansaya Bagdauletkyzy <zhansayabagdaulet@gmail.com>
Subject: selftests: vm: add KSM merge test
Patch series "add KSM selftests".
Introduce selftests to validate the functionality of KSM. The tests are
run on private anonymous pages. Since some KSM tunables are modified,
their starting values are saved and restored after testing. At the start,
run is set to 2 to ensure that only test pages will be merged (we assume
that no applications make madvise syscalls in the background). If KSM
config not enabled, all tests will be skipped.
This patch (of 4):
Add check_ksm_merge() function to check the basic merging feature of KSM.
First, some number of identical pages are allocated and the MADV_MERGEABLE
advice is given to merge these pages. Then, pages_shared and
pages_sharing values are compared with the expected numbers using
assert_ksm_pages_count() function. The number of pages can be changed
using -p option.

Subject: selftests: vm: add KSM unmerge test
Add check_ksm_unmerge() function to verify that KSM is properly unmerging
shared pages. For this, two duplicate pages are merged first and then
their contents are modified. Since they are not identical anymore, the
pages must be unmerged and the number of merged pages has to be 0. The
test is run as follows: ./ksm_tests -U

Subject: selftests: vm: add KSM zero page merging test
Add check_ksm_zero_page_merge() function to test that empty pages are
being handled properly. For this, several zero pages are allocated and
merged using madvise. If use_zero_pages is enabled, the pages must be
shared with the special kernel zero pages; otherwise, they are merged as
usual duplicate pages. The test is run as follows: ./ksm_tests -Z

Subject: selftests: vm: add KSM merging across nodes test
Add check_ksm_numa_merge() function to test that pages in different NUMA
nodes are being handled properly. First, two duplicate pages are
allocated in two separate NUMA nodes using the libnuma library. Since
there is one unique page in each node, with merge_across_nodes = 0, there
won't be any shared pages. If merge_across_nodes is set to 1, the pages
will be treated as usual duplicate pages and will be merged. If NUMA
config is not enabled or the number of NUMA nodes is less than two, then
the test is skipped. The test is run as follows: ./ksm_tests -N

Subject: selftests: vm: add KSM merging time test
Patch series "add KSM performance tests", v3.
Extend KSM self tests with a performance benchmark. These tests are not
part of regular regression testing, as they are mainly intended to be used
by developers making changes to the memory management subsystem.
This patch (of 2):
Add ksm_merge_time() function to determine speed and time needed for
merging. The total spent time is shown in seconds while speed is in
MiB/s. User must specify the size of duplicated memory area (in MiB)
before running the test.
The test is run as follows: ./ksm_tests -P -s 100
The output:
Total size: 100 MiB
Total time: 0.201106786 s
Average speed: 497.248 MiB/s

Subject: selftests: vm: add COW time test for KSM pages
Since merged pages are copied every time they need to be modified, the
write access time is different between shared and non-shared pages. Add
ksm_cow_time() function which evaluates latency of these COW breaks.
First, 4000 pages are allocated and the time, required to modify 1 byte in
every other page, is measured. After this, the pages are merged into 2000
pairs and in each pair, 1 page is modified (i.e. they are decoupled) to
detect COW breaks. The time needed to break COW of merged pages is then
compared with performance of non-shared pages.
The test is run as follows: ./ksm_tests -C
The output:
Total size: 15 MiB
Not merged pages:
Total time: 0.002185489 s
Average speed: 3202.945 MiB/s
Merged pages:
Total time: 0.004386872 s
Average speed: 1595.670 MiB/s

There is a usecase in Android that an app process's memory is swapped out
by process_madvise() with MADV_PAGEOUT, such as the memory is swapped to
zram or a backing device. When the process is scheduled to running, like
switch to foreground, multiple page faults may cause the app dropped
frames.
To reduce the problem, System Management Software can read-ahead memory
of the process immediately when the app switches to forground. Calling
process_madvise() with MADV_WILLNEED can meet this need.

This pile is:
Nacked-by: Andy Lutomirski <luto@kernel.org>
For reasons that have been discussed previously. My series is still in progress. It’s moving slowly for two reasons. First, I have limited time to work on it. Second, the existing mm refcounting is a giant pile of worms, and that needs fixing one way or another before we add yet more complexity. For example, has anyone noticed that kthread mms are refcounted using different rules than everything else?
Even if my modified refcounting scheme isn’t the eventual winner, the prerequisite cleanups are still prerequisites. I absolutely nack anything that adds yet more nonsensical complexity to the existing scheme, makes it substantially more fragile, and does not fix the underlying crap that makes speeding up responsibly such a mess.
Nick or anyone else, you’re welcome to finish up my series (and I can give pointers) or you can wait.

Can you specify exactly the range you want me to drop?
I assume it's the four patches 117-120, ie
lazy tlb: introduce lazy mm refcount helper functions
lazy tlb: allow lazy tlb mm refcounting to be configurable
lazy tlb: shoot lazies, a non-refcounting lazy tlb option
powerpc/64s: enable MMU_LAZY_TLB_SHOOTDOWN
but I just want to double-check before I do surgery on that series.

I absolutely DETEST this patch.
Code like this is just garbage:

with actively misleading names ("lock"? WTF? There's no lock there!)
and just disgusting semantics with conditionals etc.
And the thing is, I don't even see that this would be in the least required.
If that function had just been split into two: the first part that
needed to absolutely be called with interrupts disabled, and the
latter part that didn't, then none of this stupid ugly code would be
needed at all.
So flush_slab() could have been split into "that first part that
returned the freelist and page, and then the second part that did the
deactivate_slab() and the stats update.
Then somebody who had interrupts disabled anyway (ie existing cases)
would just do both.
And then the new code that you want to have with interrupts disabled
just for the first part would do the first part with interrupts
disabled, and the second part without.
See? No need for a "flags" field and odd conditional interrupt disables.
And yes, I realize that the "inline" means that *most* of the time,
the compiler will inline things, the "conditional" will become static,
and it will not be a run-time conditional.
But it's the human-readable conditional that is the ugly part here.
Now any sane human that reads that flush_slab() code will see "oh,
sometimes interrupts are disabled, and sometimes they aren't".
Because that is what the code does, at that level.
But no, what's actually going on is that interrupts are *always*
disabled - it's just that sometimes they will have already been
disabled in the caller. So all that misleading and misnamed "lock"
argument does is really "were interrupts already disabled so that I
don't need to disable and re-enable them".
That's what the code actually *does*, but it's not how the code reads,
and it's not how the code is written, or how the argument in question
is named.
So it's all very misleading, and ugly.
I'm going to sleep on this, and maybe tomorrow morning my reaction
will be "whatever, the code probably works".
But more likely, tomorrow morning I will take another look, and still
say "no, this is actually making the code less maintainable and
actively misleading", and just throw the whole slab series out the
window.

.. and I see that "mm, slub: convert kmem_cpu_slab protection to
local_lock" makes that local_irq_save() make it use a local_lock,
which may have been the cause of the naming.
But that doesn't make my other objections about this go away.
Instead of having it lock/unlock halfway through the function (and
have magic "Oh, the caller already holds the lock, so don't lock"
semantics except with misleading names) I really think that function
should just have been split in two, and then the locked region can be
minimized in the caller only taking it for the first part.

If there's some reason why it can't sanely be split into two (too many
common variables or some odd control flow or whatever), at least the
locking logic should be changed from
if (lock)
local_irq_save(flags);
to something along the lines of
if (!caller_already_locked)
local_irq_save(flags);
so that when you read that function on its own, it's clear that the
lock is always held over that critical section - and the issue is that
perhaps the lock was already taken by the caller.
This ignores the whole misleading "lock" name when it isn't even yet a lock.

Indeed.
If anyone cares, my WIP series is here:
https://git.kernel.org/pub/scm/linux/kernel/git/luto/linux.git/log/?h=sched/lazymm
It has known bugs and is definitely not ready. The major known problem is that the kthread and execve paths are still not cleaned up. (We have several different code paths that change current->mm, and they're not all quite consistent with each other.) kthread_use_mm() follows its own little set of refcounting rules that is not consistent with the scheduler's expectations, but I think it's just close enough that current kernels will not erroneously free an in-use mm or permanently leak a reference. I have half-written code to consolidate all the ->mm assignments into a single function, but it's not done.
The CPU offline issue fixed in that series seems to me like it should also affect Nick's series, but I haven't dug in. I don't immediately see why Nick's series would be able to get away without the same rearrangement I needed. (You can't *shoot* a lazy TLB entry out from under an offlined CPU -- you need to actually get rid of the reference and account for it correctly. Perhaps it's all okay in Nick's series because mmdrop() becomes a no-op and the stale logical reference doesn't actually exist.)

That's not reasonable. Andy has had complete misunderstandings about the
series which seems to stem from x86's horrible hacks that have gone in
has confused him.
My series doesn't affect x86 at all and it's no reason why Andy's series
to improve x86 can't be merged later. But that half finished series he
keeps threatening with has been sitting there for almost a year now and
it's gone nowhere, while there have been no unresolved technical
objections to mine, it works, it's simple and small.
I've kept trying to offer to help Andy with reviewing his stuff or fix
the horrible x86 hacks, but nothing.

The horrible hacks in question are almost exclusively in core code.
Here's a brief summary of the situation.
There's a messy interaction between mmget()/mmdrop() and membarrier.
membarrier currently depends on some mmget() and mmdrop() calls to be
full barriers. You make membarrier keep working by putting an ifdef'd
smp_mb() in the core scheduler. I clean up the code to make it work
independently of smp_mb() and therefore save the cost of the
unconditional barrier for non-membarrier-using programs.
Your series adds an option MMU_LAZY_TLB_REFCOUNT=n for architectures to
opt out of lazy TLB refcounting. This is simply wrong. Right now, the
core scheduler provides current->active_mm and guarantees that
current->active_mm always points to a live (possibly mm_users == 0 but
definitely not freed) mm_struct. With MMU_LAZY_TLB_REFCOUNT=n,
current->active_mm still exists, is still updated, but may point to
freed memory. I consider this unacceptable. A comment says "This can
be disabled if the architecture ensures no CPUs are using an mm as a
"lazy tlb" beyond its final refcount" -- that's nice, but saying "well,
if you this, you have to make sure you don't accidentally dereference
that juicy dangling pointer we give you" is, in my book, a poor
justification.
I have no particular objection to the actual shoot lazies part, except
insofar as I think we can do even better (e.g. my patch). But 90% of
the complexity of my WIP series is cleaning up the mess so that we can
have a maintainable lazy mm mechanism instead of expanding the current
hard-to-maintain part into three separate possible modes.
Maybe I'm holding my own patches to an excessively high standard.

My series barely touches x86. The only "hack" is that x86 may have a
CPU that has ->mm == NULL, ->active_mm != NULL, CR3 pointing to the init
pgd, and mm_cpumask clear. I don't see why this is a problem other than
being somewhat unusual. But x86 bare metal, like every architecture
that can only flush the TLB using an IPI, can very efficiently shoot
lazies, since it shoots the lazies anyway when tearing down pagetables,
but actually enabling the config option with this series applied will
result in ->active_mm pointing to freed memory. Ick.

Normally I would have done that, similarly to " [patch 033/212] mm,

I think what discouraged me was that the second part is to call
deactivate_slab() and to that we need to return two values
from the first part (page and freelist), so one of them has to be a
return parameter. On the other hand the second part does so little
it can be opencoded. See below.

Actually that "already taken" becomes "caller does not need it/can't
even take the local lock as it's not local" (it's a cpu hot remove
handler on behalf of another, dead cpu).
So would it work with something like the following cleanup on top later
after proper testing? (now just compile tested).

Membarrier has had (and is improving but still has) some complexity,
which is caused by interaction with _existing_ lazy-mm code in the tree.
The complexity is not with lazy-mm itself, and my series does not add
more to the membarrier interaction. So I don't accept the criticism
that it has to do with membarrier complexity.
> You make membarrier keep working by putting an ifdef'd

Sure, it's well commented and replaces the smp_mb provided by atomic
operation that membarrier relied on to an explicit one. That's not a
horrible hack.
> I clean up the code to make it work

Great. Nothing to do with this series though which is not changing
membarrier ordering.
I can certainly help you rebase it on top of these patches if you need.

Wrong. It does nothing of the sort. I told you this in the previous
discussion, you obviously ignored me. You are just wrong, and you can't
actually point to where this happens.
This criticism is invalid too.

It's not a justification, it's a recipe for other archs which might want

What actually happened is that when you ran out of (incorrect) technical
disputes like this confusion about the active_mm thing, you then started
to demand that I massively rework core code that you don't understand so
that it matches the horrible mess that x86 has got itself into. I can
bring up quotes from previous threads.

I'm talking about your previous insistence that my patch series removed
"active_mm" from core code, because it doesn't match x86 internals, and
similar such stupidity.

No need to be sorry about that, it will be trivial to rebase on top of
my series, I've even done a quick attempt. No problem at all.

To my eyeballs, below duplication of a couple lines of initialization
needed by the lockless function is less icky than the double return.

Subject: [PATCH] mm, slub: remove conditional locking parameter from
flush_slab()
flush_slab() is called either as part of work scheduled on given live cpu, or
called as a cleanup for another cpu that went offline. In the first case it
needs to hold the cpu_slab->lock local lock when updating the protected
kmem_cache_cpu fields. This is now achieved by a "bool lock" parameter.
To avoid the conditional locking, we can instead lock unconditionally in
flush_slab() for live cpus, and opencode the variant without locking in
__flush_cpu_slab() for the dead cpus.

Ack. Something like this seems to avoid the whole issue.
Vlastimil - the alternative I was actually going to suggest for that
"double return value" thing is something we use elsewhere in the VM
code - just use a structure for "state".
It's not hugely common, and I think Mike's solution in this case is
the much simpler one, but I'll mention it anyway because it's actually
been quite successful in the few cases we use it, and it's both
readable to humans and generates fairly good code.
The "generates fairly good code" is generally more true when inlining,
but it's not horrible even outside of that.
So the idea with the "state structure" is that you just pass in both
the arguments and the return values in a struct.
Some examples of this are
- 'struct follow_page_context' in mm/gup.c is an example of a small local one.
- 'struct vm_fault' is an example of a *big* one, that has a lot of
state, and that is actually exported as an interface.
That 'struct vm_fault' one is interesting as an example because it
does that "both inputs and outputs", and has that unnamed "const
struct" member to actually catch mis-uses where some callee would
change those fields (which is a no-no).
It's also an example of something that generates good code despite not
inlining, because it actively makes argument passing simpler and
avoids copying arguments as you call other functions.
Those issues are non-issues in this case, which is why I point to that
'follow_page_context' in the gup code as a very different example of
this, which is much more along the lines of the slub case. It's purely
local to that call chain, and it's basically used to return more
state.
In both cases, the top-level caller just initializes things on the
stack. For that 'struct vm_fault' case you actually *have* to use an
initializer, since the constant fields cannot be changed later. It
makes for pretty legible code, and when things are inlined, all those
fields actually act exactly like just regular local variables shared
across functions.
When things aren't inlined, it can generate extra memory accesses, but
that 'struct vm_fault' is an example of when that isn't even
necessarily worse.
Anyway, I wanted to just point that out as a pattern that has been
quite successful.
Side note: one very special case of that pattern goes back decades:
the VM use of structures that get returned and passed *as* structures.
It's in fact so common that people don't even think about it: 'pte_t'
and friends. They are designed to be opaque data types that are often
multi-word structures.
Quite often those structures have only one or two words in them, which
helps code generation (returning two words can be done in registers),
but they _can_ have more.
Eg x86:
typedef union {
struct {
unsigned long pte_low, pte_high;
};
pteval_t pte;
} pte_t;
or some powerpc cases:
typedef struct { pte_basic_t pte, pte1, pte2, pte3; } pte_t;
just to show that you can actually pass structures not by reference,
but by value, and it's not even unusual in the kernel. That can also
be used to return multiple values if you want to.
Note: code generation really matters, and when doing those multi-value
structures, for code generation it's generally important to limit it
to at most two words.
Anything more, and the compiler will generally be forced to pass it by
copying it to the stack and using a pointer to it, and then you get
the worst of both worlds. You're better off just passing the structure
by reference, and avoiding extra copies on the stack.
ANYWAY.
I'll drop this part from Andrew's patch-bomb, and I can take it later
in its cleaned-up form. You mentioned a git tree elsewhere, maybe even
that way.

Hmm. I think "ret" is unnecessary, and this could just have been

Ack. I did the merge of Andrew's series as-is, to avoid even more
disruption (I already skipped two sub-series in there), but wouldn't
mind this simplification.
That said, it's not like it's a big deal, just me reacting to that
patch being larger than strictly needed. It's not like the extra "ret"
thing is confusing or wrong per se.
So I'll leave it to others if they want to pursue this.

If there's no further objections that can be substanitated, then
can we merge this please?

This alternative is far from a foregone conclusion even if it does ever
get finished. It adds significant ordering complexity to core scheduler
that my approach does not have, for no benefit for powerpc and likely
no measurable benefit for others either. The first hurdle for it
obviously will be why can't x86 be updated to use this shoot-lazies
work, with actual numbers.

Greeting,
FYI, we noticed a -14.0% regression of aim7.jobs-per-min due to commit:
commit: 45208c9105bd96015b98cdf31fbd6a3bcff234b6 ("[patch 097/212] memcg: infrastructure to flush memcg stats")
url: https://github.com/0day-ci/linux/commits/Andrew-Morton/ia64-fix-typo-in-a-comment/20210903-065028
in testcase: aim7
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory
with following parameters:
disk: 1BRD_48G
fs: xfs
test: disk_rr
load: 3000
cpufreq_governor: performance
ucode: 0xd000280
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.

Greeting,
FYI, we noticed a -39.8% regression of will-it-scale.per_process_ops due to commit:
commit: 059dd9003ad894ad7b2e47126cde89a3ec46e630 ("[patch 101/212] memcg: enable accounting for file lock caches")
url: https://github.com/0day-ci/linux/commits/Andrew-Morton/ia64-fix-typo-in-a-comment/20210903-065028
in testcase: will-it-scale
on test machine: 96 threads 2 sockets Ice Lake with 256G memory
with following parameters:
nr_task: 100%
mode: process
test: lock1
cpufreq_governor: performance
ucode: 0xb000280
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
In addition to that, the commit also has significant impact on the following tests:

Greeting,
FYI, we noticed a -15.4% regression of will-it-scale.per_thread_ops due to commit:
commit: fa4e6b1ad57df096ddcf091fece3d9babfe90048 ("[patch 100/212] memcg: enable accounting for pollfd and select bits arrays")
url: https://github.com/0day-ci/linux/commits/Andrew-Morton/ia64-fix-typo-in-a-comment/20210903-065028
in testcase: will-it-scale
on test machine: 144 threads 4 sockets Intel(R) Xeon(R) CPU E7-8890 v3 @ 2.50GHz with 512G memory
with following parameters:
nr_task: 50%
mode: thread
test: poll2
cpufreq_governor: performance
ucode: 0x16
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.

I am looking into this. I was hoping we have resolution for [1] as
these patches touch similar data structures.

Because we added some operations during online/offline CPU, it's
expected that the performance of online/offline CPU will decrease. In
most cases, the performance of CPU hotplug isn't a big problem. But
then I remembers that the performance of the CPU hotplug may influence
suspend/resume performance :-(
It appears that it is easy and reasonable to enclose the added
operations inside #ifdef CONFIG_NUMA. Is this sufficient to restore the
performance of suspend/resume?
Best Regards,
Huang, Ying

It's "memhotplug", not CPUs, right?
I didn't do was to actively go out and look for changes that would
affect the migration order. The code just does regenerates and writes
the order blindly when it sees any memory hotplug event. I have the
feeling the synchronize_rcu()s are what's killing us.
It would be pretty easy to go and generate the order, but only do the
update and the RCU bits when the order changes from what was there.
I guess we have a motivation now.

Yes. Thanks for pointing that out!
We will update node_demotion[] in CPU hotplug too. Because the status
that whether a node has CPU may change after CPU hotplug. And CPU
online/offline performance may be relevant for suspend/resume.

I don't know whether the performance of memory hotplug is important or
not. But it should be welcome not to make it too bad. You proposal
sounds good.

Rui and I took a look at the default kernel config, it seems that CONFIG_NUMA is
enabled on laptops on some distributions. Maybe a runtime detecting flag indicating
that whether this system has enabled NUMA (static key eg) would be an option too, so as
not to enable node_demotion[] on non-NUMA laptops/desktops.

Got it! Thanks for your information. Maybe we can try Dave's method
firstly and check whether that's OK for suspend/resume.

I tried 2 debug methods for that 36.4% vm-scalability regression:
1. Disable the HW cache prefetcher, no effect on this case
2. relayout and add padding to 'struct cgroup_subsys_state', reduce
the regression to 3.1%
Thanks,

Thanks Feng but it seems like the issue for this commit is different.
Rearranging the layout didn't help. Actually the cause of slowdown is
the call to queue_work() inside __mod_memcg_lruvec_state().
At the moment, queue_work() is called after 32 updates. I changed it
to 128 and the slowdown of will-it-scale:page_fault[1|2|3] halved
(from around 10% to 5%). I am unable to run reaim or
will-it-scale:fallocate2 as I was getting weird errors.
Feng, is it possible for you to run these benchmarks with the change
(basically changing MEMCG_CHARGE_BATCH to 128 in the if condition
before queue_work() inside __mod_memcg_lruvec_state())?
For the formal patch/fix, I will write down a better explanation on
what should be the batch size.
thanks,
Shakeel

When I checked this, I tried different changes, including this batch
number change :), but it didn't recover the regression (the regression
is slightly reduced to about 12%)
Please check if my patch is what you want to test:
diff --git a/mm/memcontrol.c b/mm/memcontrol.c

Another change we can try is to remove this specific queue_work()
altogether because this is the only significant change for the
workload. That will give us the base performance number. If that also
has regression then there are more issues to debug. Thanks a lot for
your help.

I just tested with patch removing the queue_work() in __mod_memcg_lruvec_state(),
and the regression is gone.
Also to avoid some duplication of debugging, here are some other tries
I did:
* add padding in 'struct lruvec' for 'lru_lock', no effect
* add padding in 'mem_cgroup_per_node' between 'lruvec_stats_percpu' and
'lruvec_stats', no effect.
Thanks,
Feng

Thanks again for confirming this. I will follow this lead and see how

Hi Feng,
Would you please check if it helps fix the regression to avoid queuing a
queued work by adding and checking an atomic counter.

Hi Hillf,
I just tested your patch, and it didn't recover the regression, but
just reduced it from -14% to around -13%, similar to the patch
increasing the batch charge number.
Thanks,

Thanks Hillf for taking a look and Feng for running the test.
This shows that parallel calls to queue_work() is not the issue (there
is already a test and set at the start of queue_work()) but the actual
work done by queue_work() is costly for this code path.
I wrote a simple anon page fault nohuge c program, profiled it and it
seems like queue_work() is significant enough.
- 51.00% do_anonymous_page
+ 16.68% alloc_pages_vma
11.61% _raw_spin_lock
+ 10.26% mem_cgroup_charge
- 5.25% lru_cache_add_inactive_or_unevictable
- 4.48% __pagevec_lru_add
- 3.71% __pagevec_lru_add_fn
- 1.74% __mod_lruvec_state
- 1.60% __mod_memcg_lruvec_state
- 1.35% queue_work_on
- __queue_work
- 0.93% wake_up_process
- try_to_wake_up
- 0.82% ttwu_queue
0.61% ttwu_do_activate
- 2.97% page_add_new_anon_rmap
- 2.68% __mod_lruvec_page_state
- 2.48% __mod_memcg_lruvec_state
- 1.67% queue_work_on
- 1.53% __queue_work
- 1.25% wake_up_process
- try_to_wake_up
- 0.94% ttwu_queue
+ 0.70% ttwu_do_activate
0.61% cgroup_rstat_updated
2.10% rcu_read_unlock_strict
1.40% cgroup_throttle_swaprate
However when I switch the batch size to 128, it goes away.
Feng, do you see any change with 128 batch size for aim7 benchmark?

I did one more experiment with same workload but with system_wq
instead system_unbound_wq and there is clear difference in profile:
With system_unbound_wq:
- 4.63% 0.33% mmap [kernel.kallsyms] [k] queue_work_on
4.29% queue_work_on
- __queue_work
- 3.45% wake_up_process
- try_to_wake_up
- 2.46% ttwu_queue
- 1.66% ttwu_do_activate
- 1.14% activate_task
- 0.97% enqueue_task_fair
enqueue_entity
With system_wq:
- 1.36% 0.06% mmap [kernel.kallsyms] [k] queue_work_on
1.30% queue_work_on
- __queue_work
- 1.03% wake_up_process
- try_to_wake_up
- 0.97% ttwu_queue
0.66% ttwu_do_activate
Tejun, is this expected? i.e. queuing work on system_wq has a
different performance impact than on system_unbound_wq?

Yes, system_unbound_wq is putting the work item on the global shared
workqueue while the system_wq is per-cpu, so on a loaded system, overhead
difference showing up isn't too surprising.
Thanks.

Thanks a lot for the explanation. Are there any concerns to call
cgroup_rstat_flush_irqsafe(root_mem_cgroup->css.cgroup) in system_wq?
This will be called every 2 seconds, so, we can assume the updated
tree would be small most of the time.
Thanks,
Shakeel

I can't think of a reason why this would be problematic.

Thanks again.
Feng, is it possible to re-run these benchmarks with
queue_work(system_wq) instead of queue_work(system_unbound_wq)?

I just run the patch twice, and there was no obvious change, the
hotspot is still the spinlock.

Thanks Feng, the spinlock in lock_page_lruvec_irqsave() is unrelated
and not taken in __mod_memcg_lruvec_state().
If removing queue_work() from __mod_memcg_lruvec_state() removes the
regression then I was expecting some improvement by replacing
system_unbound_wq with system_wq. Anyways thanks for your help. I will
run some benchmarks as well (the page fault ones from will-it-scale).

Can you help to test whether the following patch can recover the
regression?

Subject: [PATCH] mm/migrate: recover hotplug performance regression
0-Day kernel test robot reported a -53.8% performance regression for
stress-ng memhotplug test case. This patch is to recover the
regression via avoid updating the demotion order if not necessary.
Refer: https://lore.kernel.org/lkml/20210905135932.GE15026@xsang-OptiPlex-9020/
