libceph: advertise support for NEW_OSDOP_ENCODING and SERVER_LUMINOUS (2017-07-07 17:26:24 +0200)
----------------------------------------------------------------
The main item here is support for v12.y.z ("Luminous") clusters:RESEND_ON_SPLIT, RADOS_BACKOFF, OSDMAP_PG_UPMAP and CRUSH_CHOOSE_ARGS feature bits, and various other changes in the RADOS client protocol. On top of that we have a new fsc mount option to allow supplying fscache uniquifier (similar to NFS) and the usual pile of filesystem fixes from Zheng.
----------------------------------------------------------------
