Summary of series in this merge:
- "mm: make VMA flag semantics explicit, eliminate VM_SPECIAL"
(Lorenzo Stoakes (ARM)):
Replace VM_SPECIAL with helpers describing mapping ownership and
behavior. Enforce the mmap flag rules and convert affected drivers,
removing ambiguous tests shared by driver mappings and ordinary memory.
- "support kselftest on nommu platform" (Hajime Tazaki):
Add opt-in mmap and mremap tests for NOMMU systems. Teach the runner to
avoid its fork-dependent timeout command and document the build and
runtime requirements.
- "mm/collapse: separate a collapse from its callers"
(Kiryl Shutsemau (Meta)):
Separate huge-page collapse from caller policy. Replace khugepaged
identity checks with explicit permissions, and separate scanning from
collapse with the mmap_lock drop in one place.
- "mm: implement and use vma_has_anon_rmap(), silence KCSAN"
(Lorenzo Stoakes (ARM)):
Provide a common helper for testing whether a VMA has anonymous reverse
mappings. Document the locking rules, annotate intentional concurrent
reads for KCSAN, and convert the core MM callers.
- "mm/sparse: remove SECTION_MARKED_PRESENT and further cleanups"
(David Hildenbrand (Arm)):
Remove SECTION_MARKED_PRESENT in favor of the early-section flag.
Simplify sparse memory initialization, section metadata handling and
related PFN validity checks.
- "sh: remove NUMA and SPARSEMEM support" (Mike Rapoport (Microsoft)):
Remove SuperH NUMA and SPARSEMEM support. The extra memory banks have
been unusable since the NO_BOOTMEM conversion, leaving only the code and
data overhead.
- "mm: Unify device DAX and HugeTLB vmemmap population paths"
(Muchun Song):
Unify the generic device DAX and HugeTLB vmemmap population paths and
shared tail-page handling. Remove the duplicate DAX machinery while
retaining the powerpc radix implementation.
- "kselftest: mm: fix some failure of split_huge_page_test" (Yeoreum Yun):
Fix huge-page split tests racing with khugepaged recollapse. Use pagemap
and page flags instead of VMA-boundary assumptions which fail when glibc
has already enabled THP.
- "memcg: move memcgid refcount to objcg to unpin dying memcgs"
(Bingfang Guo):
Let dying memcgs be freed while swapped-out shmem still holds their IDs.
Move ID references to reparentable objcgs, with the necessary swap
accounting and RCU lifetime changes.
- "mm/truncate: fix data loss when truncating straddling large folios"
(Zhang Yi):
Preserve out-of-range data when truncating straddling large folios. Fix
a lookup race and split-failure handling, and handle minimum folio orders
for the forthcoming ext4 iomap buffered I/O path.
- "mm/damon: introduce damos quota goal target metric complement flag"
(SJ Park):
Let DAMOS quota goals use a metric's complement, so utilization can also
express free-memory goals without adding separate metrics. Add the sysfs
interface, documentation and tests.
- "arm64/mm: Standardize printing for pgtable entries" (Anshuman Khandual):
Use the generic formatter for arm64 page-table entries, ready for future
wider entries. Move the safe-PTE-update check out of the header to avoid
an include cycle.
- "mm: kmsan: fix iounmap metadata teardown" (Dima Koziuk):
Fix KMSAN metadata leaks on iounmap and failed ioremap allocations. Free
backing pages before removing their mappings, and share the teardown with
partial-allocation cleanup.
- "mm/damon/core: preserve quota state when constructing schemes"
(Karl Mehltretter):
Preserve running DAMOS quota state while validating parameter updates.
Even rejected updates could reset accounting and exceed the quota window;
add tests for both accepted and rejected updates.
- "mm/vmalloc: fix vmalloc_dump_obj VA lookup" (Ye Liu):
Fix vmalloc_dump_obj() lookups for last-page addresses and allocations
spanning vmap zones. These allocations were being missed in diagnostic
output.
- "mm: various (urgent?) fixes" (David Hildenbrand (Arm)):
Fix mmap charge leaks and hugetlb use-after-free, wrong-address
unmapping, stuck locks and endless faults. Also preserve reservations on
failed mremap and handle stale userfaultfd bits.
- "maple_tree: fix maple_range_64 crashes in RCU mode" (Dimitris Charisis):
Fix pointer and metadata confusion during RCU destruction of
maple_range_64 nodes, avoiding double frees and invalid accesses. Add a
regression test; no in-tree user currently uses this combination.
- "mm: fix hugetlb NR_HUGETLB accounting on folio migration" (Hongfu Li):
Fix hugetlb migration and preallocation accounting so /proc/vmstat
retains the correct count and memory.numa_stat follows the folio to its
new node.
- "mm/damon: fix a minor bug, clean code, and add a test" (SJ Park):
Fix 32-bit DAMON age overflow which made old regions look young. Share
hugetlb folio acquisition code and add a regression test for the
previously fixed last-region skipping bug.
- "mm/damon/core: cleanup code, reduce stack usage, and add kunit"
(SJ Park):
Reduce kdamond stack usage and remove unused enums. Add deterministic
PSI quota-goal tests which do not depend on the machine's current memory
pressure.
- "mm/damon: fix the temporal goal tuner's size quota conversion"
(Donggeun Yoo):
Bound the temporal tuner's quota conversion to prevent overflow and zero
effective quotas, which could stop schemes making progress. Add boundary
tests.
- "Don't use GFP_DMA when calling dma_alloc_coherent" (Baoquan He):
Remove redundant GFP_DMA flags from coherent DMA allocation calls. The
DMA API already selects the zone from device limits and ignores the
caller's flag.
- "kselftest: mm: fix intermittent failure khugepaged test" (Yeoreum Yun):
Propagate child-process failures in the khugepaged tests and prevent
background collapse from racing their checks. This removes false passes
and intermittent failures.
- "MAINTAINERS: cover all hugetlb headers under HUGETLB SUBSYSTEM"
(Enze Li):
Cover all hugetlb headers in MAINTAINERS so get_maintainer.pl finds the
right maintainers. Also label the closing hugetlb_cgroup.h include
guard.
Summary of the 65 singletons in this merge:
The singletons include a few worthwhile performance fixes. Avoiding
unnecessary reverse-map tree updates gave a reported 15.9% improvement
in UnixBench's execl test on a 192-core x86 system. A reclaim retry fix
stops defrag_mode from spinning under memory.low protection; a reported
file-creation stress test ran 5.7 times faster, with far less memory
pressure. Narrower hugetlb invalidations also spare KVM guests needless
refaults: the reported Redis-in-VM P99 QPS penalty while punching holes
fell from 7.09% to 1.45%.
Several fixes prevent lost data or corrupted memory. Lazyfree huge-page
races with mremap()/munmap() could lose data or access freed memory, and
MADV_COLD could lose a concurrent write's dirty bit. Another fix
prevents stale migration entries from outliving large folios. On
filesystems with blocks smaller than a page, extending a file by 4 GiB
or more could expose bytes written past the old EOF through mmap instead
of zeroes. That is fixed, along with use-after-free races in
PAGEMAP_SCAN during process exit and in memory-cgroup accounting on
PREEMPT_RT kernels.
Other fixes stop UFFDIO_MOVE spinning forever on pinned large folios,
which could wedge other memory operations, and stop mremap() leaking
commit charges until allocations fail under strict overcommit. A further
fix keeps userfaultfd tracking intact on neighboring mappings. NUMA
binding no longer prevents long-term pins when the chosen node has only
movable memory, fixing QEMU/VFIO startup and io_uring buffer
registration failures. MGLRU also gets a fix for early-boot crashes with
memory cgroups disabled at boot, notably in small crash kernels.
