Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph fixes from Sage Weil: "There are two critical regression fixes for CephFS from Zheng, and an RBD completion fix for layered images from Ilya" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: rbd: fix copyup completion race ceph: always re-send cap flushes when MDS recovers ceph: fix ceph_encode_locks_to_buffer()
