Hi Linus, The following changes since commit 3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162: Linux 5.7 (2020-05-31 16:49:15 -0700) are available in the Git repository at: https://github.com/ceph/ceph-client.git tags/ceph-for-5.8-rc1 for you to fetch changes up to dc1dad8e1a612650b1e786e992cb0c6e101e226a: rbd: compression_hint option (2020-06-01 23:32:35 +0200) ---------------------------------------------------------------- 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) ---------------------------------------------------------------- Gustavo A.
