Merge tag 'ceph-for-4.15-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov:
"We have a set of file locking improvements from Zheng, rbd rw/ro state
handling code cleanup from myself and some assorted CephFS fixes from
Jeff.
rbd now defaults to single-major=Y, lifting the limit of ~240 rbd
images per host for everyone"
