mm: remove struct pagevec

2023-06-23T23:59:30+00:00

All users are now converted to use the folio_batch so we can get rid of this data structure. Link: https://lkml.kernel.org/r/20230621164557.3510324-11-willy@infradead.org Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Andrew Morton

pagevec: rename fbatch_count()

2023-06-23T23:59:29+00:00

This should always have been called folio_batch_count(). Link: https://lkml.kernel.org/r/20230621164557.3510324-8-willy@infradead.org Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Andrew Morton

mm: add __folio_batch_release()

2023-06-23T23:59:28+00:00

This performs the same role as __pagevec_release(), ie skipping the check for batch length of 0. Link: https://lkml.kernel.org/r/20230621164557.3510324-3-willy@infradead.org Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Andrew Morton

mm: pagevec: add folio_batch_reinit()

2023-02-03T06:33:04+00:00

Patch series "update mlock to use folios", v4. This series updates mlock to use folios, converting the internal interface to using folios exclusively and exposing the folio interface externally. As a product of this we move to using a folio batch rather than a pagevec for mlock folios, which brings it in line with the core folio batches contained in mm/swap.c. This patch (of 5): This performs the same task as pagevec_reinit(), only modifying a folio batch rather than a pagevec.

Pull MM updates from Andrew Morton: "Most of the MM queue. A few things are still pending. Liam's maple tree rework didn't make it. This has resulted in a few other minor patch series being held over for next time. Multi-gen LRU still isn't merged as we were waiting for mapletree to stabilize. The current plan is to merge MGLRU into -mm soon and to later reintroduce mapletree, with a view to hopefully getting both into 6.1-rc1. Summary: - The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe Lin, Yang Shi, Anshuman Khandual and Mike Rapoport - Some kmemleak fixes from Patrick Wang and Waiman Long - DAMON updates from SeongJae Park - memcg debug/visibility work from Roman Gushchin - vmalloc speedup from Uladzislau Rezki - more folio conversion work from Matthew Wilcox - enhancements for coherent device memory mapping from Alex Sierra - addition of shared pages tracking and CoW support for fsdax, from Shiyang Ruan - hugetlb optimizations from Mike Kravetz - Mel Gorman has contributed some pagealloc changes to improve latency and realtime behaviour. - mprotect soft-dirty checking has been improved by Peter Xu - Many other singleton patches all over the place" [ XFS merge from hell as per Darrick Wong in https://lore.kernel.org/all/YshKnxb4VwXycPO8@magnolia/ ] * tag 'mm-stable-2022-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (282 commits) tools/testing/selftests/vm/hmm-tests.c: fix build mm: Kconfig: fix typo mm: memory-failure: convert to pr_fmt() mm: use is_zone_movable_page() helper hugetlbfs: fix inaccurate comment in hugetlbfs_statfs() hugetlbfs: cleanup some comments in inode.c hugetlbfs: remove unneeded header file hugetlbfs: remove unneeded hugetlbfs_ops forward declaration hugetlbfs: use helper macro SZ_1{K,M} mm: cleanup is_highmem() mm/hmm: add a test for cross device private faults selftests: add soft-dirty into run_vmtests.sh selftests: soft-dirty: add test for mprotect mm/mprotect: fix soft-dirty check in can_change_pte_writable() mm: memcontrol: fix potential oom_lock recursion deadlock mm/gup.c: fix formatting in check_and_migrate_movable_page() xfs: fail dax mount if reflink is enabled on a partition mm/memcontrol.c: remove the redundant updating of stats_flush_threshold userfaultfd: don't fail on unrecognized features hugetlb_cgroup: fix wrong hugetlb cgroup numa stat ...

mm/swap: make __pagevec_lru_add static

2022-07-04T01:08:45+00:00

__pagevec_lru_add has no callers outside swap.c, so make it static, and move it to a more logical position in the file. Link: https://lkml.kernel.org/r/20220617175020.717127-4-willy@infradead.org Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Andrew Morton

pagevec: Initialise folio_batch->percpu_pvec_drained

2022-01-13T21:50:50+00:00

When UBSAN is enabled, it reports an invalid value in __pagevec_release() when accessing pvec->percpu_pvec_drained, which is simply whatever garbage was on the stack. Initialise it when initialising the rest of the folio_batch. Fixes: 10331795fb79 ("pagevec: Add folio_batch") Reported-by: Randy Dunlap Tested-by: Randy Dunlap Signed-off-by: Matthew Wilcox (Oracle)
