The following changes since commit 0518dbe97fe629fea255318841cf3ef1b4532d66: selftests/mm: fix cross compilation with LLVM (2023-06-19 13:19:35 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm tags/mm-stable-2023-06-24-19-15 for you to fetch changes up to acc72d59c7509540c27c49625cb4b5a8db1f1a84: mm/hugetlb: remove hugetlb_set_page_subpool() (2023-06-23 16:59:33 -0700) ---------------------------------------------------------------- - Yosry Ahmed brought back some cgroup v1 stats in OOM logs. - Yosry has also eliminated cgroup's atomic rstat flushing. - Nhat Pham adds the new cachestat() syscall. It provides userspace with the ability to query pagecache status - a similar concept to mincore() but more powerful and with improved usability. - Mel Gorman provides more optimizations for compaction, reducing the prevalence of page rescanning. - Lorenzo Stoakes has done some maintanance work on the get_user_pages() interface. - Liam Howlett continues with cleanups and maintenance work to the maple tree code. Peng Zhang also does some work on maple tree. - Johannes Weiner has done some cleanup work on the compaction code. - David Hildenbrand has contributed additional selftests for get_user_pages(). - Thomas Gleixner has contributed some maintenance and optimization work for the vmalloc code. - Baolin Wang has provided some compaction cleanups, - SeongJae Park continues maintenance work on the DAMON code. - Huang Ying has done some maintenance on the swap code's usage of device refcounting. - Christoph Hellwig has some cleanups for the filemap/directio code. - Ryan Roberts provides two patch series which yield some rationalization of the kernel's access to pte entries - use the provided APIs rather than open-coding accesses. - Lorenzo Stoakes has some fixes to the interaction between pagecache and directio access to file mappings. - John Hubbard has a series of fixes to the MM selftesting code. - ZhangPeng continues the folio conversion campaign. - Hugh Dickins has been working on the pagetable handling code, mainly with a view to reducing the load on the mmap_lock. - Catalin Marinas has reduced the arm64 kmalloc() minimum alignment from 128 to 8. - Domenico Cerasuolo has improved the zswap reclaim mechanism by reorganizing the LRU management. - Matthew Wilcox provides some fixups to make gfs2 work better with the buffer_head code. - Vishal Moola also has done some folio conversion work. - Matthew Wilcox has removed the remnants of the pagevec code - their functionality is migrated over to struct folio_batch. ---------------------------------------------------------------- Ackerley Tng (1): fs: hugetlbfs: set vma policy only when needed for allocating folio Alexey Romanov (1): mm/zsmalloc: get rid of PAGE_MASK Anders Roxell (1): selftests: damon: add config file Andrew Morton (2): mm/mlock: rename mlock_future_check() to mlock_future_ok() Merge mm-hotfixes-stable into mm-stable to pick up depended-upon changes.
