[0/6] Filesystem page flags cleanup

Message

Matthew Wilcox Oct. 2, 2024, 4:01 a.m. UTC

I think this pile of patches makes most sense to take through the VFS
tree.  The first four continue the work begun in 02e1960aafac to make the
mappedtodisk/owner_2 flag available to filesystems which don't use
buffer heads.  The last two remove uses of Private2 (we're achingly
close to being rid of it entirely, but that doesn't seem like it'll
land this merge window).

Matthew Wilcox (Oracle) (6):
  fs: Move clearing of mappedtodisk to buffer.c
  nilfs2: Convert nilfs_copy_buffer() to use folios
  mm: Remove PageMappedToDisk
  btrfs: Switch from using the private_2 flag to owner_2
  ceph: Remove call to PagePrivate2()
  migrate: Remove references to Private2
