[GIT PULL] MM updates for 6.2-rc1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

  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.
