Sat, 18 Apr 2026 01:35:49 +0200

Merge tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfsPull ntfs resurrection from Namjae Jeon: "Ever since Kari Argillander’s 2022 report [1] regarding the state of the ntfs3 driver, I have spent the last 4 years working to provide full write support and current trends (iomap, no buffer head, folio), enhanced performance, stable maintenance, utility support including fsck for NTFS in Linux. This new implementation is built upon the clean foundation of the original read-only NTFS driver, adding: - Write support: Implemented full write support based on the classic read-only NTFS driver. Added delayed allocation to improve write performance through multi-cluster allocation and reduced fragmentation of the cluster bitmap. - iomap conversion: Switched buffered IO (reads/writes), direct IO, file extent mapping, readpages, and writepages to use iomap. - Remove buffer_head: Completely removed buffer_head usage by converting to folios. As a result, the dependency on CONFIG_BUFFER_HEAD has been removed from Kconfig. - Stability improvements: The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3. All tests passed by ntfs3 are a complete subset of the tests passed by this implementation. Added support for fallocate, idmapped mounts, permissions, and more. xfstests Results report: Total tests run: 787 Passed : 326 Failed : 38 Skipped : 423 Failed tests breakdown: - 34 tests require metadata journaling - 4 other tests: 094: No unwritten extent concept in NTFS on-disk format 563: cgroup v2 aware writeback accounting not supported 631: RENAME_WHITEOUT support required 787: NFS delegation test"Link: https://lore.kernel.org/all/da20d32b-5185-f40b-48b8-2986922d8b25@stargateuniverse.net/ [1][ Let's see if this undead filesystem ends up being of the "Easter miracle" kind, or the "Nosferatu of filesystems" kind... ]* tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs: (46 commits) ntfs: remove redundant out-of-bound checks ntfs: add bound checking to ntfs_external_attr_find ntfs: add bound checking to ntfs_attr_find ntfs: fix ignoring unreachable code warnings ntfs: fix inconsistent indenting warnings ntfs: fix variable dereferenced before check warnings ntfs: prefer IS_ERR_OR_NULL() over manual NULL check ntfs: harden ntfs_listxattr against EA entries ntfs: harden ntfs_ea_lookup against malformed EA entries ntfs: check $EA query-length in ntfs_ea_get ntfs: validate WSL EA payload sizes ntfs: fix WSL ea restore condition ntfs: add missing newlines to pr_err() messages ntfs: fix pointer/integer casting warnings ntfs: use ->mft_no instead of ->i_ino in prints ntfs: change mft_no type to u64 ntfs: select FS_IOMAP in Kconfig ntfs: add MODULE_ALIAS_FS ntfs: reduce stack usage in ntfs_write_mft_block() ntfs: fix sysctl table registration and path ...

Merge tag 'mm-stable-2025-10-01-19-00' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mmPull MM updates from Andrew Morton: - "mm, swap: improve cluster scan strategy" from Kairui Song improves performance and reduces the failure rate of swap cluster allocation - "support large align and nid in Rust allocators" from Vitaly Wool permits Rust allocators to set NUMA node and large alignment when perforning slub and vmalloc reallocs - "mm/damon/vaddr: support stat-purpose DAMOS" from Yueyang Pan extend DAMOS_STAT's handling of the DAMON operations sets for virtual address spaces for ops-level DAMOS filters - "execute PROCMAP_QUERY ioctl under per-vma lock" from Suren Baghdasaryan reduces mmap_lock contention during reads of /proc/pid/maps - "mm/mincore: minor clean up for swap cache checking" from Kairui Song performs some cleanup in the swap code - "mm: vm_normal_page*() improvements" from David Hildenbrand provides code cleanup in the pagemap code - "add persistent huge zero folio support" from Pankaj Raghav provides a block layer speedup by optionalls making the huge_zero_pagepersistent, instead of releasing it when its refcount falls to zero - "kho: fixes and cleanups" from Mike Rapoport adds a few touchups to the recently added Kexec Handover feature - "mm: make mm->flags a bitmap and 64-bit on all arches" from Lorenzo Stoakes turns mm_struct.flags into a bitmap. To end the constant struggle with space shortage on 32-bit conflicting with 64-bit's needs - "mm/swapfile.c and swap.h cleanup" from Chris Li cleans up some swap code - "selftests/mm: Fix false positives and skip unsupported tests" from Donet Tom fixes a few things in our selftests code - "prctl: extend PR_SET_THP_DISABLE to only provide THPs when advised" from David Hildenbrand "allows individual processes to opt-out of THP=always into THP=madvise, without affecting other workloads on the system". It's a long story - the [1/N] changelog spells out the considerations - "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on the memdesc project. Please see https://kernelnewbies.org/MatthewWilcox/Memdescs and https://blogs.oracle.com/linux/post/introducing-memdesc - "Tiny optimization for large read operations" from Chi Zhiling improves the efficiency of the pagecache read path - "Better split_huge_page_test result check" from Zi Yan improves our folio splitting selftest code - "test that rmap behaves as expected" from Wei Yang adds some rmap selftests - "remove write_cache_pages()" from Christoph Hellwig removes that function and converts its two remaining callers - "selftests/mm: uffd-stress fixes" from Dev Jain fixes some UFFD selftests issues - "introduce kernel file mapped folios" from Boris Burkov introduces the concept of "kernel file pages". Using these permits btrfs to account its metadata pages to the root cgroup, rather than to the cgroups of random inappropriate tasks - "mm/pageblock: improve readability of some pageblock handling" from Wei Yang provides some readability improvements to the page allocator code - "mm/damon: support ARM32 with LPAE" from SeongJae Park teaches DAMON to understand arm32 highmem - "tools: testing: Use existing atomic.h for vma/maple tests" from Brendan Jackman performs some code cleanups and deduplication under tools/testing/ - "maple_tree: Fix testing for 32bit compiles" from Liam Howlett fixes a couple of 32-bit issues in tools/testing/radix-tree.c - "kasan: unify kasan_enabled() and remove arch-specific implementations" from Sabyrzhan Tasbolatov moves KASAN arch-specific initialization code into a common arch-neutral implementation - "mm: remove zpool" from Johannes Weiner removes zspool - an indirection layer which now only redirects to a single thing (zsmalloc) - "mm: task_stack: Stack handling cleanups" from Pasha Tatashin makes a couple of cleanups in the fork code - "mm: remove nth_page()" from David Hildenbrand makes rather a lot of adjustments at various nth_page() callsites, eventually permitting the removal of that undesirable helper function - "introduce kasan.write_only option in hw-tags" from Yeoreum Yun creates a KASAN read-only mode for ARM, using that architecture's memory tagging feature. It is felt that a read-only mode KASAN is suitable for use in production systems rather than debug-only - "mm: hugetlb: cleanup hugetlb folio allocation" from Kefeng Wang does some tidying in the hugetlb folio allocation code - "mm: establish const-correctness for pointer parameters" from Max Kellermann makes quite a number of the MM API functions more accurate about the constness of their arguments. This was getting in the way of subsystems (in this case CEPH) when they attempt to improving their own const/non-const accuracy - "Cleanup free_pages() misuse" from Vishal Moola fixes a number of code sites which were confused over when to use free_pages() vs __free_pages() - "Add Rust abstraction for Maple Trees" from Alice Ryhl makes the mapletree code accessible to Rust. Required by nouveau and by its forthcoming successor: the new Rust Nova driver - "selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and some cleanups to the thp selftesting code - "mm, swap: introduce swap table as swap cache (phase I)" from Chris Li and Kairui Song is the first step along the path to implementing "swap tables" - a new approach to swap allocation and state tracking which is expected to yield speed and space improvements. This patchset itself yields a 5-20% performance benefit in some situations - "Some ptdesc cleanups" from Matthew Wilcox utilizes the new memdesc layer to clean up the ptdesc code a little - "Fix va_high_addr_switch.sh test failure" from Chunyu Hu fixes some issues in our 5-level pagetable selftesting code - "Minor fixes for memory allocation profiling" from Suren Baghdasaryan addresses a couple of minor issues in relatively new memory allocation profiling feature - "Small cleanups" from Matthew Wilcox has a few cleanups in preparation for more memdesc work - "mm/damon: add addr_unit for DAMON_LRU_SORT and DAMON_RECLAIM" from Quanmin Yan makes some changes to DAMON in furtherance of supporting arm highmem - "selftests/mm: Add -Wunreachable-code and fix warnings" from Muhammad Anjum adds that compiler check to selftests code and fixes the fallout, by removing dead code - "Improvements to Victim Process Thawing and OOM Reaper Traversal Order" from zhongjinji makes a number of improvements in the OOM killer: mainly thawing a more appropriate group of victim threads so they can release resources - "mm/damon: misc fixups and improvements for 6.18" from SeongJae Park is a bunch of small and unrelated fixups for DAMON - "mm/damon: define and use DAMON initialization check function" from SeongJae Park implement reliability and maintainability improvements to a recently-added bug fix - "mm/damon/stat: expose auto-tuned intervals and non-idle ages" from SeongJae Park provides additional transparency to userspace clients of the DAMON_STAT information - "Expand scope of khugepaged anonymous collapse" from Dev Jain removes some constraints on khubepaged's collapsing of anon VMAs. It also increases the success rate of MADV_COLLAPSE against an anon vma - "mm: do not assume file == vma->vm_file in compat_vma_mmap_prepare()" from Lorenzo Stoakes moves us further towards removal of file_operations.mmap(). This patchset concentrates upon clearing up the treatment of stacked filesystems - "mm: Improve mlock tracking for large folios" from Kiryl Shutsemau provides some fixes and improvements to mlock's tracking of large folios. /proc/meminfo's "Mlocked" field became more accurate - "mm/ksm: Fix incorrect accounting of KSM counters during fork" from Donet Tom fixes several user-visible KSM stats inaccuracies across forks and adds selftest code to verify these counters - "mm_slot: fix the usage of mm_slot_entry" from Wei Yang addresses some potential but presently benign issues in KSM's mm_slot handling* tag 'mm-stable-2025-10-01-19-00' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (372 commits) mm: swap: check for stable address space before operating on the VMA mm: convert folio_page() back to a macro mm/khugepaged: use start_addr/addr for improved readability hugetlbfs: skip VMAs without shareable locks in hugetlb_vmdelete_list alloc_tag: fix boot failure due to NULL pointer dereference mm: silence data-race in update_hiwater_rss mm/memory-failure: don't select MEMORY_ISOLATION mm/khugepaged: remove definition of struct khugepaged_mm_slot mm/ksm: get mm_slot by mm_slot_entry() when slot is !NULL hugetlb: increase number of reserving hugepages via cmdline selftests/mm: add fork inheritance test for ksm_merging_pages counter mm/ksm: fix incorrect KSM counter handling in mm_struct during fork drivers/base/node: fix double free in register_one_node() mm: remove PMD alignment constraint in execmem_vmalloc() mm/memory_hotplug: fix typo 'esecially' -> 'especially' mm/rmap: improve mlock tracking for large folios mm/filemap: map entire large folio faultaround mm/fault: try to map the entire file folio in finish_fault() mm/rmap: mlock large folios in try_to_unmap_one() mm/rmap: fix a mlock race condition in folio_referenced_one() ...

Tue, 26 Aug 2025 05:09:55 +0200

Revert "hugetlb: make hugetlb depends on SYSFS or SYSCTL"Commit f8142cf94d47 ("hugetlb: make hugetlb depends on SYSFS or SYSCTL")added dependency on SYSFS or SYSCTL but hugetlb can be used without SYSFSor SYSCTL. So this dependency is wrong and should be removed.For users with CONFIG_SYSFS or CONFIG_SYSCTL on, there should be nodifference. For users have CONFIG_SYSFS and CONFIG_SYSCTL bothundefined, hugetlbfs can still works perfectly well through cmdlineexcept a possible kismet warning[1] when select CONFIG_HUGETLBFS. IMHO, it might not worth a backport.This reverts commit f8142cf94d4737ea0c3baffb3b9bad8addcb9b6b. Itoverlooked the scenario of using hugetlb through boot parameters whenit was submitted.Link: https://lkml.kernel.org/r/20250826030955.2898709-1-linmiaohe@huawei.comLink: https://lore.kernel.org/all/5c99458f-4a91-485f-8a35-3618a992e2e4@csgroup.eu/ [1]Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202508222032.bwJsQPZ1-lkp@intel.com/Signed-off-by: Miaohe Lin Cc: David Hildenbrand Cc: Muchun Song Cc: Oscar Salvador Signed-off-by: Andrew Morton List of files: /linux/fs/Kconfig
