Bah.

I forgot to call fscache_op_complete().  Patch updated and repushed.

Btw, I've reordered the patches to put the CIFS patch last.  Can you merge the
patches prior to the CIFS commit from my branch rather than cherry picking
them so that if they go via two different routes, GIT will handle the merge
correctly?  I've stuck a tag on it (fscache-fixes-for-ceph) to make that
easier for you.

I've also asked another RH engineer to try doing some basic testing on the
CIFS stuff - which may validate the fscache_readpages_cancel patch.
