mm: Don't hog the CPU and zone lock in rmqueue_bulk()
There is noticeable scheduling latency and heavy zone lock contention stemming from rmqueue_bulk's single hold of the zone lock while doing its work, as seen with the preemptoff tracer. There's no actual need for rmqueue_bulk() to hold the zone lock the entire time; it only does so for supposed efficiency. As such, we can relax the zone lock and even reschedule when IRQs are enabled in order to keep the scheduling delays and zone lock contention at bay. Forward progress is still guaranteed, as the zone lock can only be relaxed after page removal. With this change, rmqueue_bulk() no longer appears as a serious offender in the preemptoff tracer, and system latency is noticeably improved. Signed-off-by: Sultan Alsawaf <sultan@kerneltoast.com> |

UPSTREAM: mm: count time in drain_all_pages during direct reclaim as memory pressure
When page allocation in direct reclaim path fails, the system will make
one attempt to shrink per-cpu page lists and free pages from high alloc
reserves. Draining per-cpu pages into buddy allocator can be a very slow
operation because it's done using workqueues and the task in direct
reclaim waits for all of them to finish before proceeding. Currently this
time is not accounted as psi memory stall.
While testing mobile devices under extreme memory pressure, when
allocations are failing during direct reclaim, we notices that psi events
which would be expected in such conditions were not triggered. After
profiling these cases it was determined that the reason for missing psi
events was that a big chunk of time spent in direct reclaim is not
accounted as memory stall, therefore psi would not reach the levels at
which an event is generated. Further investigation revealed that the bulk
of that unaccounted time was spent inside drain_all_pages call.
A typical captured case when drain_all_pages path gets activated:
__alloc_pages_slowpath took 44.644.613ns
__perform_reclaim took 751.668ns (1.7%)
drain_all_pages took 43.887.167ns (98.3%)
PSI in this case records the time spent in __perform_reclaim but ignores
drain_all_pages, IOW it misses 98.3% of the time spent in
__alloc_pages_slowpath.
Annotate __alloc_pages_direct_reclaim in its entirety so that delays from
handling page allocation failure in the direct reclaim path are accounted
as memory stall.

BACKPORT: mm, compaction: capture a page under direct compaction
Compaction is inherently race-prone as a suitable page freed during
compaction can be allocated by any parallel task. This patch uses a
capture_control structure to isolate a page immediately when it is freed
by a direct compactor in the slow path of the page allocator. The
intent is to avoid redundant scanning.

Latency is only moderately affected but the devil is in the details. A
closer examination indicates that base page fault latency is reduced but
latency of huge pages is increased as it takes creater care to succeed.
Part of the "problem" is that allocation success rates are close to 100%
even when under pressure and compaction gets harder

BACKPORT: mm, compaction: ignore the fragmentation avoidance boost for isolation and compaction
When pageblocks get fragmented, watermarks are artifically boosted to reclaim pages to avoid further fragmentation events. However, compaction is often either fragmentation-neutral or moving movable pages away from unmovable/reclaimable pages. As the true watermarks are preserved, allow compaction to ignore the boost factor. The expected impact is very slight as the main benefit is that compaction is slightly more likely to succeed when the system has been fragmented very recently. On both 1-socket and 2-socket machines for THP-intensive allocation during fragmentation the success rate was increased by less than 1% which is marginal. However, detailed tracing indicated that failure of migration due to a premature ENOMEM triggered by watermark checks were eliminated.

BACKPORT: ANDROID: mm: freeing MIGRATE_ISOLATE page instantly
Since Android has pcp list for MIGRATE_CMA[1], it could cause
CMA allocation latency due to not freeing the MIGRATE_ISOLATE
page immediately.
Originally, MIGRATE_ISOLATED page is supposed to go buddy list
with skipping pcp list. Otherwise, the page could be reallocated
from pcp list or staying on the pcp list until the pcp is drained
so that CMA keeps retrying since it couldn't find the freed page
from buddy list. That worked before since the CMA pfnblocks changed
only from MIGRATE_CMA to MIGRATE_ISOLATE and free function logic
in page allocator has checked MIGRATE_ISOLATEness on every CMA
pages using below.
free_unref_page_commit
if (migratetype >= MIGRATE_PCPTYPES)
if(is_migrate_isolate(migratetype))
free_one_page(page);
It worked since enum MIGRATE_CMA was bigger than enum
MIGRATE_PCPTYPES but since [1], the enum MIGRATE_CMA is less than
MIGRATE_PCPTYPES so the logic above doesn't work any more.
It could cause following race
CPU 0 CPU 1
free_unref_page
migratetype = get_pfnblock_migratetype()
set_pcppage_migratetype(MIGRATE_CMA)
cma_alloc
alloc_contig_range
set_migrate_isolate(MIGRATE_ISOLATE)
add the page into pcp list
the page could be reallocated
This patch couldn't fix the race completely due to missing zone->lock
in order-0 page free(for performance reason). However, it's not a new
problem so we need to deal with the issue separately.

FROMLIST: BACKPORT: mm: fix is_pinnable_page against on cma page
Pages on CMA area could have MIGRATE_ISOLATE as well as MIGRATE_CMA
so current is_pinnable_page could miss CMA pages which has MIGRATE_
ISOLATE. It ends up pinning CMA pages as longterm at pin_user_pages
APIs so CMA allocation keep failed until the pin is released.

internal_get_user_pages_fast

try_grab_folio
is_pinnable_page
return true;
So, pinned the page successfully.
page migration failure with pinned page
..
.. After 30 sec
unpin_user_page(page)
CMA allocation succeeded after 30 sec.
The CMA allocation path protects the migration type change race
using zone->lock but what GUP path need to know is just whether the
page is on CMA area or not rather than exact migration type.
Thus, we don't need zone->lock but just checks migration type in
either of (MIGRATE_ISOLATE and MIGRATE_CMA).
Adding the MIGRATE_ISOLATE check in is_pinnable_page could cause
rejecting of pinning pages on MIGRATE_ISOLATE pageblocks even
though it's neither CMA nor movable zone if the page is temporarily
unmovable. However, such a migration failure by unexpected temporal
refcount holding is general issue, not only come from MIGRATE_ISOLATE
and the MIGRATE_ISOLATE is also transient state like other temporal
elevated refcount problem.

FROMLIST: mm: multi-gen LRU: support page table walks
To further exploit spatial locality, the aging prefers to walk page
tables to search for young PTEs and promote hot pages. A kill switch
will be added in the next patch to disable this behavior. When
disabled, the aging relies on the rmap only.
NB: this behavior has nothing similar with the page table scanning in
the 2.4 kernel [1], which searches page tables for old PTEs, adds cold
pages to swapcache and unmaps them.
To avoid confusion, the term "iteration" specifically means the
traversal of an entire mm_struct list; the term "walk" will be applied
to page tables and the rmap, as usual.
An mm_struct list is maintained for each memcg, and an mm_struct
follows its owner task to the new memcg when this task is migrated.
Given an lruvec, the aging iterates lruvec_memcg()->mm_list and calls
walk_page_range() with each mm_struct on this list to promote hot
pages before it increments max_seq.
When multiple page table walkers iterate the same list, each of them
gets a unique mm_struct; therefore they can run concurrently. Page
table walkers ignore any misplaced pages, e.g., if an mm_struct was
migrated, pages it left in the previous memcg will not be promoted
when its current memcg is under reclaim. Similarly, page table walkers
will not promote pages from nodes other than the one under reclaim.
This patch uses the following optimizations when walking page tables:
1. It tracks the usage of mm_struct's between context switches so that
page table walkers can skip processes that have been sleeping since
the last iteration.
2. It uses generational Bloom filters to record populated branches so
that page table walkers can reduce their search space based on the
query results, e.g., to skip page tables containing mostly holes or
misplaced pages.
3. It takes advantage of the accessed bit in non-leaf PMD entries when
CONFIG_ARCH_HAS_NONLEAF_PMD_YOUNG=y.
4. It does not zigzag between a PGD table and the same PMD table
spanning multiple VMAs. IOW, it finishes all the VMAs within the
range of the same PMD table before it returns to a PGD table. This
improves the cache performance for workloads that have large
numbers of tiny VMAs [2], especially when CONFIG_PGTABLE_LEVELS=5.

mm, compaction: raise compaction priority after it withdrawns
Mike Kravetz reports that "hugetlb allocations could stall for minutes or hours when should_compact_retry() would return true more often then it should. Specifically, this was in the case where compact_result was COMPACT_DEFERRED and COMPACT_PARTIAL_SKIPPED and no progress was being made." The problem is that the compaction_withdrawn() test in should_compact_retry() includes compaction outcomes that are only possible on low compaction priority, and results in a retry without increasing the priority. This may result in furter reclaim, and more incomplete compaction attempts. With this patch, compaction priority is raised when possible, or should_compact_retry() returns false. The COMPACT_SKIPPED result doesn't really fit together with the other outcomes in compaction_withdrawn(), as that's a result caused by insufficient order-0 pages, not due to low compaction priority. With this patch, it is moved to a new compaction_needs_reclaim() function, and for that outcome we keep the current logic of retrying if it looks like reclaim will be able to help.

find free pages easily so free scanner of compaction were not moved fast like that. That means it wouldn't fail for non-costly high-order allocation. What this patch does is if the order is non-costly high order allocation, it will keep trying migration with reclaiming if system has enough reclaimable memory.

mm: prevent page_frag_alloc() from corrupting the memory
commit dac22531bbd4af2426c4e29e05594415ccfa365d upstream.
A number of drivers call page_frag_alloc() with a fragment's size >
PAGE_SIZE.
In low memory conditions, __page_frag_cache_refill() may fail the order
3 cache allocation and fall back to order 0; In this case, the cache
will be smaller than the fragment, causing memory corruptions.
Prevent this from happening by checking if the newly allocated cache is
large enough for the fragment; if not, the allocation will fail and
page_frag_alloc() will return NULL.

mm/page_alloc: fix race condition between build_all_zonelists and page allocation
commit 3d36424b3b5850bd92f3e89b953a430d7cfc88ef upstream. Patrick Daly reported the following problem; NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - before offline operation [0] - ZONE_MOVABLE [1] - ZONE_NORMAL [2] - NULL For a GFP_KERNEL allocation, alloc_pages_slowpath() will save the offset of ZONE_NORMAL in ac->preferred_zoneref. If a concurrent memory_offline operation removes the last page from ZONE_MOVABLE, build_all_zonelists() & build_zonerefs_node() will update node_zonelists as shown below. Only populated zones are added. NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - after offline operation [0] - ZONE_NORMAL [1] - NULL [2] - NULL The race is simple -- page allocation could be in progress when a memory hot-remove operation triggers a zonelist rebuild that removes zones. The allocation request will still have a valid ac->preferred_zoneref that is now pointing to NULL and triggers an OOM kill. This problem probably always existed but may be slightly easier to trigger due to |

mm: page_alloc: fix building error on -Werror=array-compare
commit ca831f29f8f25c97182e726429b38c0802200c8f upstream.
Arthur Marsh reported we would hit the error below when building kernel
with gcc-12:
CC mm/page_alloc.o
mm/page_alloc.c: In function `mem_init_print_info':
mm/page_alloc.c:8173:27: error: comparison between two arrays [-Werror=array-compare]
8173 | if (start <= pos && pos < end && size > adj) \
|
In C++20, the comparision between arrays should be warned.
