Linus, please merge the MM updates for this release cycle. I'm seeing two minor conflicts here: - a clash with the block tree in mm/hugetlb.c. Stephen resolved it thusly: https://lkml.kernel.org/r/20221110172246.32792d6a@xxxxxxxxxxxxxxxx - also drivers/media/common/videobuf2/frame_vector.c, Stephen's fix is at https://lkml.kernel.org/r/20221207130140.7c014015@xxxxxxxxxxxxxxxx Thanks. The following changes since commit 4a7ba45b1a435e7097ca0f79a847d0949d0eb088: memcg: fix possible use-after-free in memcg_write_event_control() (2022-12-09 18:41:17 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm tags/mm-stable-2022-12-13 for you to fetch changes up to c45bc55a99957b20e4e0333bcd42e12d1833a7f5: mm/hugetlb: set head flag before setting compound_order in __prep_compound_gigantic_folio (2022-12-12 16:47:11 -0800) ---------------------------------------------------------------- MM patches for 6.2-rc1. - More userfaultfs work from Peter Xu. - Several convert-to-folios series from Sidhartha Kumar and Huang Ying. - Some filemap cleanups from Vishal Moola. - David Hildenbrand added the ability to selftest anon memory COW handling. - Some cpuset simplifications from Liu Shixin. - Addition of vmalloc tracing support by Uladzislau Rezki. - Some pagecache folioifications and simplifications from Matthew Wilcox. - A pagemap cleanup from Kefeng Wang: we have VM_ACCESS_FLAGS, so use it. - Miguel Ojeda contributed some cleanups for our use of the __no_sanitize_thread__ gcc keyword. This series shold have been in the non-MM tree, my bad. - Naoya Horiguchi improved the interaction between memory poisoning and memory section removal for huge pages. - DAMON cleanups and tuneups from SeongJae Park - Tony Luck fixed the handling of COW faults against poisoned pages. - Peter Xu utilized the PTE marker code for handling swapin errors. - Hugh Dickins reworked compound page mapcount handling, simplifying it and making it more efficient. - Removal of the autonuma savedwrite infrastructure from Nadav Amit and David Hildenbrand. - zram support for multiple compression streams from Sergey Senozhatsky. - David Hildenbrand reworked the GUP code's R/O long-term pinning so that drivers no longer need to use the FOLL_FORCE workaround which didn't work very well anyway. - Mel Gorman altered the page allocator so that local IRQs can remnain enabled during per-cpu page allocations. - Vishal Moola removed the try_to_release_page() wrapper. - Stefan Roesch added some per-BDI sysfs tunables which are used to prevent network block devices from dirtying excessive amounts of pagecache. - David Hildenbrand did some cleanup and repair work on KSM COW breaking. - Nhat Pham and Johannes Weiner have implemented writeback in zswap's zsmalloc backend. - Brian Foster has fixed a longstanding corner-case oddity in file[map]_write_and_wait_range(). - sparse-vmemmap changes for MIPS, LoongArch and NIOS2 from Feiyang Chen. - Shiyang Ruan has done some work on fsdax, to make its reflink mode work better under xfstests. Better, but still not perfect. - Christoph Hellwig has removed the .writepage() method from several filesystems. They only need .writepages(). - Yosry Ahmed wrote a series which fixes the memcg reclaim target beancounting. - David Hildenbrand has fixed some of our MM selftests for 32-bit machines. - Many singleton patches, as usual. ---------------------------------------------------------------- Alexander Gordeev (1): mm: mmu_gather: do not expose delayed_rmap flag Alexander Potapenko (4): Revert
