From: Linus Torvalds Date: Mon, 8 Jun 2020 19:49:18 +0000 (-0700) Subject: Merge tag 'ceph-for-5.8-rc1' of git://github.com/ceph/ceph-client X-Git-Tag: v5.10.7~2392 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=95288a9b3beee8dd69d73b7691e36f2f231b7903;p=platform%2Fkernel%2Flinux-rpi.git 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)" * tag 'ceph-for-5.8-rc1' of git://github.com/ceph/ceph-client: (29 commits) rbd: compression_hint option libceph: support for alloc hint flags libceph: read_from_replica option libceph: support for balanced and localized reads libceph: crush_location infrastructure libceph: decode CRUSH device/bucket types and names libceph: add non-asserting rbtree insertion helper ceph: skip checking caps when session reconnecting and releasing reqs ceph: make sure mdsc->mutex is nested in s->s_mutex to fix dead lock ceph: don't return -ESTALE if there's still an open file libceph, rbd: replace zero-length array with flexible-array ceph: allow rename operation under different quota realms ceph: normalize 'delta' parameter usage in check_quota_exceeded ceph: ceph_kick_flushing_caps needs the s_mutex ceph: request expedited service on session's last cap flush ceph: convert mdsc->cap_dirty to a per-session list ceph: reset i_requested_max_size if file write is not wanted ceph: throw a warning if we destroy session with mutex still locked ceph: fix potential race in ceph_check_caps ceph: document what protects i_dirty_item and i_flushing_item ... --- 95288a9b3beee8dd69d73b7691e36f2f231b7903
