Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull ceph fixes from Sage Weil:
"These fix several bugs with RBD from 3.11 that didn't get tested in
time for the merge window: some error handling, a use-after-free, and
a sequencing issue when unmapping and image races with a notify
operation.
There is also a patch fixing a problem with the new ceph + fscache
code that just went in"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
fscache: check consistency does not decrement refcount
rbd: fix error handling from rbd_snap_name()
rbd: ignore unmapped snapshots that no longer exist
rbd: fix use-after free of rbd_dev->disk
rbd: make rbd_obj_notify_ack() synchronous
rbd: complete notifies before cleaning up osd_client and rbd_dev
libceph: add function to ensure notifies are complete
