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
