Subject: [PATCH v2 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.

F2fs and Ceph have quite alot of work to be done regarding folios, so
for now those patches only have the changes necessary for the removal of
find_get_pages_range_tag(), and only support folios of size 1 (which is
all they use right now anyways).

I've run xfstests on btrfs, ext4, f2fs, and nilfs2, but more testing may be
beneficial. The page-writeback and filemap changes implicitly work. Testing
and review of the other changes (afs, ceph, cifs, gfs2) would be appreciated.
