[GIT PULL] Ceph fixes for -rc2

[Sage Weil]

Hi Linus,

Please pull the following Ceph fixes from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

We have a few follow-up fixes for the libceph refactor from Ilya, and then 
some cephfs + fscache fixes from Zheng.  The first two FS-Cache patches 
are acked by David Howells and deemed trivial enough to go through our 
tree.  The rest fix some issues with the ceph fscache handling (disable 
cache for inodes opened for write, and simplify the revalidation logic 
accordingly, dropping the now-unnecessary work queue).

Thanks!
sage
