[PATCH v2 0/6] netfs, afs, ceph: Support folios, at least partially

[David Howells <dhowells@redhat.com>]

Here's a set of patches to convert netfs and afs to use folios and to
provide sufficient conversion for ceph that it can continue to use the
netfs library.  Jeff Layton is working on fully converting ceph.

This based on top of part of Matthew Wilcox's folio changes[1]

Changes:

ver #2:
 - Reorder the patches to put both non-folio afs patches to the front.
 - Use page_offset() rather than manual calculation[2].
 - Fix folio_inode() to directly access the inode[3].
