Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph updates from Sage Weil: "This time around we have a collection of CephFS fixes from Zheng around MDS failure handling and snapshots, support for a new CRUSH straw2 algorithm (to sync up with userspace) and several RBD cleanups and fixes from Ilya, an error path leak fix from Taesoo, and then an assorted collection of cleanups from others" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (28 commits) rbd: rbd_wq comment is obsolete libceph: announce support for straw2 buckets crush: straw2 bucket type with an efficient 64-bit crush_ln() crush: ensuring at most num-rep osds are selected crush: drop unnecessary include from mapper.c ceph: fix uninline data function ceph: rename snapshot support ceph: fix null pointer dereference in send_mds_reconnect() ceph: hold on to exclusive caps on complete directories libceph: simplify our debugfs attr macro ceph: show non-default options only libceph: expose client options through debugfs libceph, ceph: split ceph_show_options() rbd: mark block queue as non-rotational libceph: don't overwrite specific con error msgs ceph: cleanup unsafe requests when reconnecting is denied ceph: don't zero i_wrbuffer_ref when reconnecting is denied ceph: don't mark dirty caps when there is no auth cap ceph: keep i_snap_realm while there are writers libceph: osdmap.h: Add missing format newlines ...
