Pull f2fs updates from Jaegeuk Kim:
"In this round, key enhancements focus on reducing inode management
memory overhead, introducing resizable tail sections with unified
pinned allocation, and boosting I/O throughput via parallel
multi-device flushes and asynchronous f2fs_write_end_io() execution.
We also add dynamic device alias reservations to allow on-the-fly
space donation from user partitions.
Alongside these features, critical bug fixes resolve folio race
conditions, lingering dirty flags, dentry and block counter leaks, and
potential deadloops in f2fs_fsync_node_pages(). Additional stability
patches address error-path handling across symlink, sync, and
rename/unlink operations, prevent pinned file fragmentation, and
correct segment migration and free section accounting in
free_segment_range.
Enhancements:
- reduce memory footprint of ino management
- support dynamic reserve/release for device aliasing
- issue multi-device flushes in parallel
- add a way to run f2fs_write_end_io() asynchronously
- support resizable tail section and unify pinned allocation
Bug fixes:
- fix to pass folio->index to f2fs_sanity_check_node_footer()
- fix folio_nr_pages() race after put in large folio invalidate
- fix to clear dirty flag on folio in error path
- accurately adjust free_sections during free_segment_range
- fix to avoid potential deadloop in f2fs_fsync_node_pages()
- fix the error path in symlink, device alias in rename/unlink,
f2fs_sync_fs
- fix to migrate all curseg types during free_segment_range
- fix to avoid pinfile fragment on fragment:{block, segment} mode
- fix valid block count leak on data block allocation failure
- fix dentry folio leak in find_in_level
- reject overlapping move range after len expansion
- fix some bugs related to file pinning, GC functions, i_size
And, the series includes a number of minor bug fixes"

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 kvm updates from Paolo Bonzini:
"ARM64:
- Add support for 'slot' based PMU events, paired with new UAPI that
compels the user to select a specific PMU implementation
- Lazy save/restore of vCPU state for pKVM, along with various fixes
and cleanups to the management of vCPU state between the untrusted
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 ee1a586dd1fa "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!"

Extend the allocinfo filtering mechanism to allow users to filter tags
based on the total number of bytes allocated [min_size, max_size]. The
size range is inclusive.
Filtering by size involves retrieving allocinfo per-CPU counters, which is
an expensive operation. Hence, the performance of size-based filtering
will be worse than other filters.

Patch series "alloc_tag: introduce IOCTL-based filtering for MAP", v8.
Currently, memory allocation profiling data is primarily exposed through
/proc/allocinfo. While useful for manual inspection, this text-based
interface poses challenges for production monitoring and large-scale
analysis:
1. Userspace must parse large amounts of text to extract specific
fields.
2. To find specific tags, userspace must read the entire dataset,
requiring many context switches and high data copying.
3. The kernel currently aggregates per-CPU counters for every allocation
size, even those the user intends to filter out immediately.
This series introduces a new IOCTL-based binary interface for allocinfo
that supports kernel-side filtering. By allowing the user to specify a
filter mask, we significantly reduce the work performed in-kernel and the
amount of data transferred to userspace. The IOCTL mechanism was chosen
for allocinfo to address the per-CPU counter aggregation bottleneck. A
traditional read() operation must report the total allocation count and
sizes for every code tag in the system. Doing so requires iterating
across all CPUs to sum their per-CPU counters for thousands of tags, which
introduces substantial runtime overhead.
The IOCTL interface allows userspace to push selective filtering criteria
directly into the kernel before the per-CPU counter aggregation. The
kernel aggregates per-CPU counters only for a small subset of tags that
match the filter. This results in significant performance improvement.
Beyond fast filtered retrieval, the IOCTL foundation allows introducing a
context capture mechanism in the future to capture the context for
specific allocations.
Performance measurements were conducted on an Intel Xeon Platinum 8481C
(224 CPUs) with caches dropped before each run.
The IOCTL mechanism shows a ~20x performance improvement for
filtered queries. The kernel avoids the expensive per-CPU counter
aggregation (alloc_tag_read) for any tags that fail the initial string
or location filters.
Scenario 1: Specific File Filtering (arch/x86/events/rapl.c)
1. Traditional (cat /proc/allocinfo | grep): 22ms (sys)
2. IOCTL Interface: 1ms (sys)
Scenario 2: Compound Filtering (Filename + Size)
1. Traditional: (cat ... | grep | awk): 21ms (sys)
2. IOCTL Interface: 1ms (sys)
Scenario 3: Size-Based Filtering (min_size = 1MB)
1. Traditional: (cat ... | awk): 21ms (sys)
2. IOCTL Interface: 14ms (sys)
This patch (of 6):
Add the following ioctl commands for /proc/allocinfo file:
ALLOCINFO_IOC_CONTENT_ID - gets content identifier which can be used to
check whether the file content has changed specifically due to module
load/unload. Every time a module is loaded / unloaded, the returned value
will be different. By comparing the identifier value at the beginning and
at the end of the content retrieval operation, users can validate
retrieved information for consistency.
ALLOCINFO_IOC_GET_AT - gets the record at the specified position. This is
the position of a record in /proc/allocinfo.
ALLOCINFO_IOC_GET_NEXT - gets the record next to the last retrieved one.
If no records were previously retrieved, returns the first record.
Note, function file and module names often have the same prefixes,
therefore when filtering for them, we compare the last 64 characters to
minimize the chances of name collisions.

Add explicit padding before launch_time so xsk_tx_metadata has the same
layout on 32-bit and 64-bit systems.
On several architectures (csky, i386, nios2, m65k, openrisc, sh), the old
native 32-bit layout put launch_time at offset 12 and had a natural size of
20 bytes. Using sizeof(struct xsk_tx_metadata) as tx_metadata_len was already
rejected because the length must be a multiple of eight, so the
straightforward use of the interface was broken on those ABIs. Userspace
could still register a padded length of 24 bytes, though; mixing the old and
new layouts then silently reads launch_time from the wrong offset and
misprograms packet launch times. This intentionally replaces that
incompatible layout because the affected architectures are unlikely to
have any notable users. (x86_64 and arm64 have the most users and are _not_
affected)
