[PATCH v5 00/23] Convert to filemap_get_folios_tag()

This patch series replaces find_get_pages_range_tag() with
filemap_get_folios_tag(). This also allows the removal of multiple
calls to compound_head() throughout.
It also makes a good chunk of the straightforward conversions to folios,
and takes the opportunity to introduce a function that grabs a folio
from the pagecache.

I've run xfstests on xfs, btrfs, ext4, f2fs, and nilfs2, but more testing may
be beneficial. The page-writeback and filemap changes implicitly work. Still
looking for review of cifs, gfs2, and ext4.

v5:
Rebased onto upstream 6.2-rc2
Filesystems modified to use folio_get() instead of folio_ref_inc()
F2fs modified to maintain use of F2FS_ONSTACK_PAGES

v4:
Fixed a bug with reference counting in cifs changes
- Reported-by: kernel test robot <oliver.sang@intel.com>
Improved commit messages to be more meaningful
Got some Acked-bys and Reviewed-bys

v3:
Rebased onto upstream 6.1
Simplified the ceph patch to only necessary changes
Changed commit messages throughout to be clearer
Got an Acked-by for another nilfs patch
Got Tested-by for afs

v2:
Got Acked-By tags for nilfs and btrfs changes
Fixed an error arising in f2fs
- Reported-by: kernel test robot <lkp@intel.com>
