Take a look at:

   https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/

The "ceph-folio" branch has Willy's folio conversion patches plus a tracing
patch plus a patch that's an unsuccessful attempt by me to fix the hang I was
seeing.

The tracepoint I'm using (netfs_folio) takes a folio pointer, so it was easier
to do it on top of Willy's patches.

The "netfs-crypto" branch are my patches to implement content crypto in
netfslib.  I've tested them to some extent with AFS, but the test code I have
in AFS only supports crypto of files where the file is an exact multiple of
page size as AFS doesn't support any sort of xattr and so I can't store the
real EOF pointer so simply.

The "ceph-iter" branch are my patches on top of a merge of those two
(excluding the debugging patches) to try and convert ceph to fully using
netfslib and to pass an iterator all the way down to the socket, aiming to
reduce the number of data types to basically two.
