Subject: [PATCHv2 00/11] Get rid of PG_reclaim and rename PG_dropbehind

Use PG_dropbehind instead of PG_reclaim and remove PG_reclaim.

After removing PG_relcaim, PG_readahead is exclusive user of the page
flag bit.

Once PG_reclaim is gone, we can rename PG_dropbehind to PG_reclaim.

Kirill A. Shutemov (11):
  mm/migrate: Transfer PG_dropbehind to the new folio
  drm/i915/gem: Convert __shmem_writeback() to folios
  drm/i915/gem: Use PG_dropbehind instead of PG_reclaim
  mm/zswap: Use PG_dropbehind instead of PG_reclaim
  mm/truncate: Use folio_set_dropbehind() instead of
    deactivate_file_folio()
  mm/vmscan: Use PG_dropbehind instead of PG_reclaim
  mm/vmscan: Use PG_dropbehind instead of PG_reclaim in
    shrink_folio_list()
  mm/mglru: Check PG_dropbehind instead of PG_reclaim in
    lru_gen_folio_seq()
  mm: Remove PG_reclaim
  mm/vmscan: Do not demote PG_dropbehind folios
  mm: Rename PG_dropbehind to PG_reclaim
