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.
