Merge tag 'ceph-for-5.8-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov:
"The highlights are:
- OSD/MDS latency and caps cache metrics infrastructure for the
filesytem (Xiubo Li). Currently available through debugfs and will
be periodically sent to the MDS in the future.
- support for replica reads (balanced and localized reads) for rbd
and the filesystem (myself). The default remains to always read
from primary, users can opt-in with the new crush_location and
read_from_replica options. Note that reading from replica is safe
for general use only since Octopus.
- support for RADOS allocation hint flags (myself). Currently used by
rbd to propagate the compressible/incompressible hint given with
the new compression_hint map option and ready for passing on more
advanced hints, e.g. based on fadvise() from the filesystem.
- support for efficient cross-quota-realm renames (Luis Henriques)
- assorted cap handling improvements and cleanups, particularly
untangling some of the locking (Jeff Layton)"
