[v2,00/19] Convert aops->migratepage to aops->migrate_folio

Message

Matthew Wilcox (Oracle) June 8, 2022, 3:02 p.m. UTC

We're getting to the last aops that take a struct page.  The only
remaining ones are ->writepage, ->write_begin, ->write_end and
->error_remove_page.

Changes from v1:
 - Remove ->isolate_page from secretmem
 - Split the movable_operations from address_space_operations
 - Drop the conversions of balloon, zsmalloc and z3fold
 - Fix the build errors with hugetlbfs
 - Fix the kerneldoc errors
 - Fix the ;; typo

  secretmem: Remove isolate_page
  mm: Convert all PageMovable users to movable_operations

  mm/migrate: Convert buffer_migrate_page() to buffer_migrate_folio()
  mm/migrate: Convert expected_page_refs() to folio_expected_refs()
  btrfs: Convert btree_migratepage to migrate_folio
  nfs: Convert to migrate_folio
  mm/migrate: Convert migrate_page() to migrate_folio()
  mm/migrate: Add filemap_migrate_folio()
