fscache and cachefiles should be taken care of by my patchset here:
https://lore.kernel.org/r/163363935000.1980952.15279841414072653108.stgit@warthog.procyon.org.uk
https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=fscache-remove-old-io
With that 9p, afs and ceph use netfs lib to handle readpage, readahead and
part of write_begin.
nfs and cifs do their own wrangling of readpages/readahead, but will call out
to the cache directly to handle each page individually. At some point, cifs
will hopefully be converted to use netfs lib.
