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.

Merge tag 'mm-stable-2022-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

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"

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.

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.
