Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (59 commits) ceph: reuse mon subscribe message instead of allocated anew ceph: avoid resending queued message to monitor ceph: Storage class should be before const qualifier ceph: all allocation functions should get gfp_mask ceph: specify max_bytes on readdir replies ceph: cleanup pool op strings ceph: Use kzalloc ceph: use common helper for aborted dir request invalidation ceph: cope with out of order (unsafe after safe) mds reply ceph: save peer feature bits in connection structure ceph: resync headers with userland ceph: use ceph. prefix for virtual xattrs ceph: throw out dirty caps metadata, data on session teardown ceph: attempt mds reconnect if mds closes our session ceph: clean up send_mds_reconnect interface ceph: wait for mds OPEN reply to indicate reconnect success ceph: only send cap releases when mds is OPEN|HUNG ceph: dicard cap releases on mds restart ceph: make mon client statfs handling more generic ceph: drop src address(es) from message header [new protocol feature] ...
