Here's a patch that fixes what seems to be a showstopping bug in cifs-fscache. *Any time* that a fscache read hit occurs on a mounted cifs filesystem (and therefore cifs_readpage_worker is called), the page lock on the read page is leaked, causing subsequent accesses to the page to deadlock. I've been running my machine for the past week with this change and it seems to work, but I'm a little concerned that this may mean cifs-fscache has no users (besides me). Up to you (maintainers) whether that means you should accept this patch... or delete the fscache support.
