18fbf5151d Merge tag 'mm-stable-2026-08-26-15-22' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm 
Pull more MM updates from Andrew Morton:

 - "mm/rmap: index MAP_PRIVATE file-backed folios by anonymous pgoff"
   (Lorenzo Stoakes)

   Index MAP_PRIVATE file-backed folios by their anonymous page offset
   to resolve confusion around reverse mapping for zeroed and CoW'd
   file-backed memory.

   Use this new VMA anonymous page offset tracking to eliminate index
   conflicts and lay the foundation for scalable CoW performance
   improvements.

 - "promote mapped executable folios after first usage for MGLRU"
   (Baolin Wang)

   Make MGLRU's protection of mapped executable file folios more
   reliable. Follow the classical LRU's logic, promoting mapped
   executable file folios after their first usage to give executable
   code a better chance to stay in memory and improve workload
   performance.

 - "mm: vmscan: fix node reclaim ignoring swappiness parameter" (Ridong
   Chen)

   Fix per-node proactive reclaim interface's ignoring the swappiness
   parameter when CONFIG_MEMCG is disabled by consolidating
   sc_swappiness() into a single function that checks
   proactive_swappiness regardless of kernel configuration.

 - "mm/vmscan: reduce lru_lock contention via vmstat-derived
   scan-balance cost" (Usama Arif)

   Reduce lru_lock contention in the reclaim path by deriving
   scan-balance costs from vmstat counters rather than lock-acquired
   producer updates.

   Read and decay these cost signals on the reclaim side under a
   dedicated per-lruvec lock, reducing total LRU lock wait time by over
   60% without impacting scan throughput.

 - "zram: fix zram issues reported by sashiko" (Sergey Senozhatsky)

   Fix two low-risk zram bugs which Sashiko spotted in drive-by review.

 - "Honor XA_FLAGS_ACCOUNT in xas_split_alloc() and charge to folio's
   memcg" (Zi Yan)

   Fix xas_split_alloc() by enabling target folio memcg charging during
   splits and adding the missing __GFP_ACCOUNT flag for proper XArray
   node memory accounting.

 - "selftests/mm: use pattern matching in .gitignore" (Pratyush Mallick)

   Replace hardcoded binary names in selftests/mm/.gitignore with a
   generic pattern-matching rule to automatically ignore generated test
   files and avoid manual updates when adding new tests.

 - "mm/page_ext: remove pgdat_page_ext_init()" (Sang-Heon Jeon)

   Make the incompatibility between FLATMEM and NUMA explicit in
   mm/Kconfig and remove the unused pgdat_page_ext_init() function.

 - "zram: fix zstd error paths and add parameter validation" (Haoqin
   Huang)

   Clean up zram compression backends by removing redundant error
   cleanup, adding parameter and dictionary validation, auto-prefixing
   algorithm error logs, and resetting parameters prior to
   reinitialization.

 - "zram: fix stale scan bounds after reinitialization" (Longlong Xia)

   Prevent out-of-bounds slot accesses during concurrent zram resets by
   moving table scan bound calculations under dev_lock in
   writeback_store() and read_block_state().

 - "add anon mTHP collapse test cases" (Baolin Wang)

   Extend selftests helper functions to support arbitrary page orders
   and add new test cases and options for mTHP collapse in khugepaged.

 - "selftests/mm: Handle unsupported and transient test conditions"
   (Muhammad Usama Anjum)

   Update MM selftests to report a SKIP status instead of a failure when
   required kernel or filesystem features are unsupported, while adding
   retry logic for transient page migration errors.

 - "mm/zswap: Fixes and improves the zswap shrink" (Hao Jia)

   Fix the missing zswap global shrinker when CONFIG_MEMCG is disabled
   and extend shrink_memcg() to support batch writeback for improved
   writeback efficiency.

 - "alloc_tag: introduce IOCTL-based filtering for MAP" (Suren
   Baghdasaryan)

   Introduce an IOCTL-based binary interface for memory allocation
   profiling that enables kernel-side filtering before per-CPU counter
   aggregation.

   This eliminates the text-parsing overhead of /proc/allocinfo and
   provides up to a 20x speedup by transferring only filtered allocation
   data to userspace.

 - "better block swap batching and a different take on swap_ops v5"
   (Christoph Hellwig)

   Refactor block swap I/O to use swap_iocb for batching instead of
   single-bio requests and rebase the swap_ops interface, achieving
   faster swap throughput during kernel builds.

 - "mm: kmemleak: reduce transient false positives by confirming leaks"
   (Catalin Marinas)

   Reduce false-positive kmemleak reports by combining two kmemleak
   enhancements that add a second confirmation scan and a configurable
   minimum unreferenced scan count module parameter.

 - "mm: kmemleak: default min_unref_scans to 2 for verbose kernels"
   (Breno Leitao)

   Auto-scanning kernels can generate false-positive memory leak reports
   on single scans, so this patch defaults min_unref_scans to 2 when
   CONFIG_DEBUG_KMEMLEAK_VERBOSE is enabled to require a second
   confirming scan.

 - "swap_ops updates" (Christoph Hellwig)

   Batching I/O for synchronous swap devices causes performance
   regressions and filesystem-based swap suffers from double-indirection
   overhead. This series resolves both issues by reintroducing per-folio
   writes for synchronous swap and allowing filesystems to directly
   export their own swap_ops.

 - "mm/khugepaged: several cleanups" (Nico Pache)

   khugepaged accumulated redundant state-checking patterns and outdated
   comments following mTHP integration. Introduce dedicated helpers for
   PTE validation and event counting while refreshing the internal
   documentation.

 - "maple_tree: lock checking and clean ups" (Liam Howlett)

   Syzbot reports incorrectly blame memory management exit paths for
   locking bugs, maple tree erase operations risk allocation failures
   without gfp flags and internal documentation lacks clarity.

   Improve lock error detection, update docs, fix race and allocation
   edge cases and optimize erase allocations using a fallback to
   GFP_KERNEL | GFP_NOFAIL.

Pull runtime verification fix from Steven Rostedt:

 - Use .old instead of .bak for rvgen kunit backup files

   The rvgen kunit command generates .bak backup files and these are
   checked in for selftests as "golden" files for make check. But
   'make distclean' removes such files, leaving the tree dirty.

   Switch to .old to preserve a clean tree after make disclean.

502d45774a Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux 
Pull clk updates from Stephen Boyd:
 "Mostly the usual clk driver updates and new SoC additions plus
  non-critical data fixes for things that weren't used yet.

  One thing that's new here in the core is SSC spread spectrum support
  (SSC) in the clk provider API. The idea is that DT authors will
  configure SSC for certain clks and they'll be configured at clk
  provider registration time or when a consumer device is probed,
  similar to how we handle assigned clk rates or parents.

  On the clk driver side we have Qualcomm adding almost half the diff
  because they add support for 4 different SoCs and then a long tail of
  other SoCs like Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more
  SoC support this time around. Luckily it's mostly clk data for these
  new SoCs because the actual clk_ops are already there. Beyond the new
  drivers we get all the little fixups for more compilation coverage or
  usage of more modern APIs. That all looks normal.

  Finally, I kinda buried the lede, I'm bringing on Brian and Jerome to
  help out with maintaining the clk subsystem. The current working model
  is already semi-distributed in that silicon vendors typically take
  care of their drivers and send me pull requests but I'm becoming a
  bottleneck for new drivers and core framework review because this has
  become a 100% volunteer effort on my part.

  Mike is stepping down after all these years (thanks Mike!) and that
  jump started the conversation around finding co-maintainers. Brian and
  Jerome have graciously offered to help me with the work load, meaning
  in the future they'll be sending pull requests and committing directly
  to the clk.git tree. They've both been around on the list for a while,
  I've met them both in person, and they've been making changes to the
  core clk framework along with helping review patches so I'm pretty
  confident this will work well.

  Core:
   - devm_clk_bulk_get_enable() consumer API
   - devm_clk_hw_register_composite_pdata() provider API
   - Spread Spectrum Clock (SSC) support via DT bindings and provider APIs
   - Divider clk rounding improved (and tested)

   - Cix Sky1 audio subsystem (AUDSS)
   - UltraRISC DP1000

Pull AppArmor updates from John Johansen:
 "The biggest functional change is Jann Horn's fix for how aparmor is
  doing stale cred updates after a policy replacement.

     apparmor: fix cred UAF caused by begin_current_label_crit_section()

  It moves the update to be done during task_work at the end of the
  syscall.

  One major feature is allowing policy to be compressed in userspace
  instead of after the fact (in kernel) if we need to hold onto it for
  CRIU/introspection.

  The other major change is to do with network mediation. It is a lot of
  code churn but does not do any functional changes to mediation. It
  moves the code around, and refactors it to use newer patterns for
  consistency, and in preparation for some improvements in mediation in
  a future patchset.

  Features:
   - support loading compressed policies
   - add audit mode to provide a mechanism to silence complain messages
   - refactor network mediation to use new patterns, and prepare to for
     extended inet mediation (no functional change)

  Cleanups:
   - switch website link to https
   - make include headers self-contained, and fix circular include
   - constify aa_label, aa_dfa, aa_profile, and aa_perms paraneters
   - mark static tables and structs as read only
   - drop use of _confined variant for iteration
   - refactory mount to use check_perms
   - refactor network mediation code to be together
   - refactor xattr attachment, to take the file path
   - optimize current_label_crit_section()
   - leverage audit_log_n_untrustedstring() when possible

  Bug Fixes:
   - initialized policy lists heads before fail path
   - fix deadlock in complain-mode change_hat
   - auditing of mount binary data
   - fix error debug output in fn_label_build
   - fix race condition in label replacement
   - fix unconfined user namespace restriction forced stack
   - fix error handling for copy_from_user in policy_update
   - fix out-of-bounds write when null terminating a label vec
   - fix integer overflow in verify_tags() bounds check
   - fix cred UAF caused by begin_current_label_crit_section()
   - use SEND_SIG_NOINFO instead of NULL in aa_audit()"

 "A single tree-wide rename of two of the public functions to better

   - rename pwrseq_power_on/off() to pwrseq_enable/disable() tree-wide"

* tag 'pwrseq-updates-for-v7.3-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:

Bartosz Golaszewski
d51fc9d4cd power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable() 
The way power sequencing works means that a call to pwrseq_power_on()
does not necessarily result in the pwrseq target being powered-on at
that time: it may have already been powered on before. Similarly: a call
to pwrseq_power_off() does not have to result in an actual powering off
of resources: there may still be other users that requested a power-on
before.

We will also introduce the concept of "non-controllable" pwrseq targets
soon which further increases the disconnect between the naming
convention and the actual semantics.

What consumers of pwrseq descriptors actually do is: they *vote* for a
powering on of a given target or retract that vote. These operations
could be called get/put in line with runtime PM but this could become
confusing since we already provide pwrseq_get/put() for a different
purpose. pwrseq_vote_on/off() also have been rejected as unusual in
the tree.

Change the name of the two functions to pwrseq_enable/disable() which
better reflects their purpose and semantics and also mirrors other
enable-counted resources like regulators and clocks. No functional change
intended.

If at any point users need to know *when* the exact power event happens,
we can provide that information in the form of a notifier.

     host and pKVM hypervisor

   - Disable traps of EL1 registers for nested hypervisors when
     FEAT_NV2p1 is present, guaranteeing that EL2-specific register bits
     are stateful in the EL1 counterpart

   - Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the
     scope of those instructions remains 'in host' (i.e. L1
     kernel/userspace)

   - Pile of fixes for the management of the VNCR pseudo-TLB, such as
     under-invalidations and races with concurrent TLBIs on other vCPUs

   - Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
     runtime-patched constant, allowing the same data to be shared with
     pKVM prior to dropping host privileges

   - Considerable pile of LLM-assisted fixes around the shop but mostly
     in the VGIC, our in-kernel generator of bugs (and sometimes
     interrupts)

  LoongArch:

   - Advertise already-supported capabilities

   - Some bug fixes about timer and MMIO

   - Some hardening about interrupt injection

   - Replace kvm_err() with kvm_pr_unimpl()

   - Add FPU/LSX/LASX test cases for selftests

  RISC-V:

   - Svadu/Zicfiss/Zicfilp FWFT support for Guest

   - Use try_cmpxchg for IMSIC MRIF RMW

   - More arch-specific tracepoints in KVM RISC-V

   - Eager page splitting when enabling dirty logging

   - Optimize hfence request handling for SMP Guests

   - Improve dirty log clearing by skipping zero bits in mask

   - Guard HFENCE range loops against overflow

   - CPU PM notifiers in KVM RISC-V for non-retentive idle states

   - Fix kernel-mode vector context save/restore for Guest

  s390:

   - Fixes for vfio-ap

   - Fixes for the gmap rework

   - Fixes for vsie

   - AI triggered fixes all over

   - diag9c tracing

   - code move preparation for the additional arm64 support

   - enable CONTEXT_ANALYSIS

  x86:

   - Perform spring cleaning on x86.{c,h} and asm/kvm_host.h, by adding
     regs.c (the kvm_cache_regs.h => regs.h is already applied) and
     msrs.{c,h}, and moving relevant code out of x86.c

   - Split kvm_mmu in three parts, respectively to describe the format
     of page tables, walking the guest page tables and building the page
     tables. Always use the same page table walker kvm->arch.gva_walk as
     the entry point to convert a guest's virtual address, where the
     previous code used two different kvm_mmu structs depending on
     whether the walk included nested EPT/NPT or not. Make page fault
     vmexits reuse the permission checking machinery that is used for
     guest page faults. This is both a cleanup and a baby step towards
     supporting XS/XU memory permissions

   - Document some of the "fun" gotchas with the APIC base when creating
     IRQCHIPs on x86

   - Remove a defunct masterclock update from kvm_xen_shared_info_init().
     It could result in incorrect kvmclock due to triggering an
     unnecessary switch to/from masterclock mode

   - Skip Xen runstate time updates if time has effectively gone
     backwards, so that the guest doesn't report 100% steal time for
     a very, very long time

   - Drop KVM's runtime updates of the Xen PV timing CPUID leaf, as KVM
     was updating the wrong sub-leaf, and upstream KVM will soon provide
     all the information needed by userspace to populate the CPUID field
     itself

   - Fix a bug where KVM would walk a newly created rmap without holding
     the rmap lock (or mmu_lock) during aging

   - Fix a bug where aging TDP MMU SPTEs could clobber FROZEN SPTEs

   - Fix a variety of #DB priority bugs

   - Fix a class of races related to enabling Hyper-V emulation on a
     vCPU after the vCPU is visible to the rest of KVM

   - Use static calls for nested virtualization ops

   - Move more KVM-internal code out of x86's kvm_host.h

   - Enumerate support for a variety of Zhaoxin instructions that don't
     require explicit virtualization

   - Fix missing EFER validation bugs, including in the KVM_SET_SREGS*
     path

   - Harden kvm_vcpu_map() against double-mapping and thus leaking
     references

   - Misc fixes and cleanups, e.g. for largely benign syzkaller splats

  x86 (Intel):

   - Zero a vCPU's entry in VMX's Posted Interrupt Descriptor table used
     for IPI virtualization when the vCPU is freed, to fix a
     use-after-free where hardware will write to a freed vCPU's PID

   - Service local TLB flushes on a failed nested VM-Enter to fix a bug
     where KVM could miss a TLB on a future, successful VM-Enter with
     the same L2 VPID

   - Cap the maximum value shoved into the VMX Preemption Timer to
     workaround an erratum that affects all existing Intel CPUs that
     support CPUID 0x15

   - Fix VPID virtualization bugs where KVM would fail to flush hardware
     TLBs

   - Harden the TDX "populate" ioctls against bad input, and to prepare
     for supporting in-place private<=>shared conversion

  x86 (AMD):

   - Forcefully invalidate SNP VMSA pages if their backing guest_memfd
     page is zapped/invalidated, e.g. due to a PUNCH_HOLE in response to
     a Page-State Change request

   - Remove a dying VM from the GA Log notifier list before the VM is
     actually destroyed, to fix a potential use-after-free

   - While FOLL_WRITE was needed in the past to trigger CoW unsharing,
     nowadays FOLL_LONGTERM does that already even without FOLL_WRITE,
     and in fact, get_user_pages() actually disallows FOLL_WRITE
     together with FOLL_LONGTERM. So don't pass FOLL_WRITE when
     registering encrypted memory regions, i.e. when pinning SEV/SEV-ES
     guest memory, to fix a regression with file-backed memory
     introduced by KVM's (correct) usage of long-term pins

     (This was reviewed by mm maintainers; for more information, see
     commit ee1a586dd1 "KVM: SEV: Drop FOLL_WRITE for encrypted region
     registration")

   - Allocate full pages for SEV/SEV-ES {DE,EN}CRYPT ops on SNP-enabled
     hosts to fix a data corruption issue due to the PSP driver
     assigning to-be-written pages to firmware (as required by the SNP
     specs)

   - Unconditionally intercept ICBEP so that KVM generates the correct
     guest RIP when handling an ICEBP-induced TASK_SWITCH #VMEXIT

   - Harden the SNP "populate" ioctls against bad input, and to prepare
     for supporting in-place private<=>shared conversion

  Generic:

   - Remove kvm_debugfs_dir if kvm_init() fails after creating KVM's
     debugfs

   - Add a per-VM bitmap to track which vCPU IDs have been "claimed" but
     for which the vCPU isn't yet online, and use the bitmap to reject
     duplicate IDs before calling into arch code. This allows arch code
     to consume vcpu_id without having to worry about cross-vCPU
     clobbering (at least s390 and x86 have had related bugs)

   - Rework the so called "prepare" and "invalidate" guest_memfd hooks
     to prepare for in-place private<=>shared conversion, and clean up a
     few warts along the way

  Selftests:

   - Automatically allocate a full page for L2 guest stacks on x86
     instead of requiring test-specific L1 guest code to carve out a
     portion of the L1 stack for L2 usage, and to ensure the L2 stack
     also adheres to the x86-64 calling convention ABI

   - Add a selftest to verify {Guest,Host}-Only behavior in x86's
     mediated PMU

   - Clean up nested SVM's handling of GPRs on L2<=>L1 transitions,
     reuse the functionality for nested VMX, and drop the ucall hack
     that was fudging around the lack of GPR switching on nVMX

   - Add a stress test to verify KVM doesn't clobber/drop #PF state,
     e.g. CR2, across save/restore, including when L2 is active

   - Add a test to verify KVM_CREATE_VM accepts exactly what is reported
     by KVM_CAP_VM_TYPES

   - Misc selftests fixes and cleanups

   - Fix several issues with seeding the pRNG, and rework the pRNG APIs
     to that the pRNG can be sanely used in host code, not just guest
     code

   - Add an IRQ test to validate virtual IRQ deliverty for IRQs wired up
     via KVM_IRQFD + KVM_SET_GSI_ROUTING, with optional support for
     triggering IRQs via writes to an assigned VFIO device

   - Add syscall wrappers to assert success on a variety of pthreads and
     CPU affinity APIs

   - Set vCPU pthread affinity as early as possible to reduce contention
     issues that were surfaced by PREEMPT_LAZY, which result in runtimes
     of over a minute on large hosts, versus the expected ~5 seconds

   - Rework the PMU counters test to run each testcase using a single VM
     with many vCPUs for each sub-testcase, instead of using a unique VM
     for each sub-testcase. This cuts the runtime by ~20x

  Miscellaneous:

   - MAINTAINERS updates for vfio-ap, guest_memfd, kvm-x86. Mostly
     representing the status quo more accurately, but also... welcome
     David Hildenbrand as guest_memfd reviewer!"

7f22f3a193 Merge tag 'ntfs-for-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs 
Pull ntfs updates from Namjae Jeon:
 "This contains improvements to compression support, metadata handling,
  error propagation, and filesystem robustness.

  New feature:

   - Add optional read support for Windows System Compression (WOF)

     Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading
     WOF-compressed files through the NTFS page-read path. This includes
     parsing REPARSE_TAG_WOF, handling resident and non-resident WOF
     metadata and compressed chunks, and adding kernel-side XPRESS
     4K/8K/16K and LZX 32K decompressors. The codecs use a common
     transparent compression interface shared with LZNT1.

     WOF support is read-only and disabled unless explicitly enabled.

  Other changes:

   - Harden malformed filesystem handling and error paths.

     Add bounds and consistency checks for mapping pairs, run lengths,
     MFT locations, update-sequence offsets, non-resident attributes,
     compressed attributes, index roots, and bitmap scans. Prevent
     out-of-bounds accesses in decompression, MFT allocation, and index
     conversion paths, clean up MFT mappings and attribute search
     contexts on failure, and propagate attribute and inode
     initialization errors correctly.

   - Improve compressed-file I/O path.

     Fix compressed writes on large-page and highmem systems, reuse
     compression contexts and output workspaces, avoid unnecessary reads
     for full-unit overwrites, and submit one bio per compressed write
     unit. Write replacement data before publishing the new mapping,
     correctly handle zero-filled compressed blocks, and fix
     initialized-size and folio state updates after compressed writes.

   - Synchronize resident reads with MFT record updates.

   - Validate the final EA stream size before modifying existing data,
     rewrite the stream safely when replacing entries, restore the
     previous state when metadata updates fail, and remove the EA
     attribute pair when the last entry is deleted.

   - Apply Windows filename restrictions only when windows_names is
     enabled.

   - Allow index roots to relocate to extent MFT records when the base
     record lacks sufficient space.

   - Move non-resident attribute payload data before shrinking its
     record.

   - Correct resident-to-non-resident conversion when compression or
     sparse flags are enabled.

   - Prepare file allocation and initialized-size updates before
     buffered or direct I/O submission, and use
     pagecache_isize_extended() when extending the file size.

   - Fix highmem and page/folio access in compressed I/O paths by using
     the correct local mappings and page helpers.

   - Apply per-file $LXMOD permissions instead of mount masks when
     available, and prevent unprivileged writes to reserved $LX*
     attributes

   - Update the NTFS maintainer mailing list

   - Small cleanups"

ab0304fd69 verification/rvgen: Use .old instead of .bak for kunit backup files 
The rvgen kunit command generates .bak backup files and these can be
checked in for selftests (make check). Clean targets like make disclean
remove such files, leaving the tree dirty.

Switch to .old to preserve a clean tree after make disclean.

0685630fdc selftests/proc: make proc-maps-race work with READ_IMPLIES_EXEC 
test_maps_tearing_from_split times out when READ_IMPLIES_EXEC is set. 
This happens by default on pre-ARMv6 CPUs, which lack no-execute support.

split_vma() re-maps the first page with mod_info->prot | PROT_EXEC to make
it differ from its neighbours.  With READ_IMPLIES_EXEC the original
mapping is already executable, so no split occurs and the test hangs
waiting for the modifier child.

Use PROT_NONE for the split mapping, which always differs from its
readable neighbours.

0e0ac326c5 memcg: move LRU size accounting on reparenting instead of copying it 
When a memory cgroup is offlined its LRU folios are reparented to the
parent.  lruvec_reparent_lru() splices the child's lists into the
parent's and credits the parent with the child's per-zone
lru_zone_size[], but never clears the child's copy, so the size is
copied rather than moved.  lru_gen_reparent_memcg() does the same for
MGLRU.

The parent is left correct, credited with exactly the folios it took
over.  The stale value sits on the child and nothing will correct it:
folio->memcg_data now resolves to the parent, so every later
update_lru_size() for those folios goes there.

Dying cgroups are not freed immediately and mem_cgroup_iter() still
walks them, so shrink_lruvec() keeps being called on them.
get_scan_count() reads the phantom counter through lruvec_lru_size() and
the scan loop then grinds through nr[] in SWAP_CLUSTER_MAX steps against
an empty list, for as long as the dead cgroup lives.  Under MGLRU the
MGLRU scanner runs instead, but count_shadow_nodes() sums all of
NR_LRU_LISTS through lruvec_lru_size() and over-budgets the shadow node
limit just the same.

On one 251 GiB host a sweep of every mz->lru_zone_size[] found 380
counters describing folios on no list at all: 124777314 pages, 476 GiB,
1.89x the machine's RAM, across 57 cgroups.  All were on memcgs with
CSS_DYING set and CSS_ONLINE clear, and parent/child pairs reported
byte-identical sizes.

LRU_UNEVICTABLE needs its size moved too.  Its list is deliberately not
spliced because lruvec_init() poisons the head - the unevictable LRU is
imaginary and folios are never threaded on it - but the size is kept by
lruvec_add_folio()/lruvec_del_folio() and those folios account to the
parent from here on.

This depends on commit bf4ade7dbd ("memcg: keep folio's objcg same as
its node") and must not be backported ahead of it.  Without that
invariant a folio's objcg can belong to another node, so a folio already
spliced onto the parent's list can still resolve to the child's lruvec
until the objcg's node is reparented in a later iteration of
memcg_reparent_objcgs(); clearing the child's counter early then lets
lruvec_del_folio() underflow it and trip the WARN_ONCE()/VM_BUG_ON() in
mem_cgroup_update_lru_size().

Prior to ending the ascension loop of larger operations like split,
rebalance, and spanning store the gap in the node had been calculated. 
Once the node is inserted into the tree, the gap is recalculated in
mas_update_gap().  This can be avoided by creating a helper for
mas_update_gap() that accepts the known gap value, which reduces the
operations required for gap updating path.

35f1342e5b maple_tree: catch race in mas_alloc_cyclic() 
If mas_alloc_cyclic() is called during a low memory situation, it is
possible the lock may be dropped so reclaim can occur.  There is a window
where some other task may allocate the same id and cause the mas_insert()
to fail with -EEXIST.  In this scenario the function will return -EEXIST,
which is not expected.

Modifying the retry on mas_nomem() to re-search for a slot means that any
race with other writes will not matter as the lock will be held between
finding the index and writing the index.

Moving the flag logic avoids cases where the flag is modified on drop
lock/reacquire or when the write fails after clearing the flag.

No existing users are exposed to this issue.
