[PATCH v2 0/9] Remove aops->writepage

[Matthew Wilcox (Oracle)]

We have just one filesystm (vboxsf) left which implements ->writepage.
This patchset converts it to writepages then removes all the callers
of ->writepage.

v1: https://lore.kernel.org/linux-mm/20250307135414.2987755-1-willy@infradead.org/
v2:
 - Added ttm patch
 - Remove f2fs patches as they were merged
 - Add 9p patch
 - Add warning in migration code about aops which set writepages but not
   migrate_folio

Matthew Wilcox (Oracle) (9):
  9p: Add a migrate_folio method
  vboxsf: Convert to writepages
  migrate: Remove call to ->writepage
  writeback: Remove writeback_use_writepage()
  shmem: Add shmem_writeout()
  i915: Use writeback_iter()
  ttm: Call shmem_writeout() from ttm_backup_backup_page()
  mm: Remove swap_writepage() and shmem_writepage()
  fs: Remove aops->writepage
