Here's a set of patches to convert netfs, 9p 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 has been rebased on to the 9p merge in Linus's tree[5] so that it has

Ran basic tests on 9p with this; it'd probably deserve a bit more
soak-in but at least doesn't seem to break anything obvious:
