Merge tag 'ceph-for-5.7-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "The main items are: - support for asynchronous create and unlink (Jeff Layton). Creates and unlinks are satisfied locally, without waiting for a reply from the MDS, provided the client has been granted appropriate caps (new in v15.y.z ("Octopus") release). This can be a big help for metadata heavy workloads such as tar and rsync. Opt-in with the new nowsync mount option. - multiple blk-mq queues for rbd (Hannes Reinecke and myself). When the driver was converted to blk-mq, we settled on a single blk-mq queue because of a global lock in libceph and some other technical debt. These have since been addressed, so allocate a queue per CPU to enhance parallelism. - don't hold onto caps that aren't actually needed (Zheng Yan). This has been our long-standing behavior, but it causes issues with some active/standby applications (synchronous I/O, stalls if the standby goes down, etc). - .snap directory timestamps consistent with ceph-fuse (Luis Henriques)" * tag 'ceph-for-5.7-rc1' of git://github.com/ceph/ceph-client: (49 commits) ceph: fix snapshot directory timestamps ceph: wait for async creating inode before requesting new max size ceph: don't skip updating wanted caps when cap is stale ceph: request new max size only when there is auth cap ceph: cleanup return error of try_get_cap_refs() ceph: return ceph_mdsc_do_request() errors from __get_parent() ceph: check all mds' caps after page writeback ceph: update i_requested_max_size only when sending cap msg to auth mds ceph: simplify calling of ceph_get_fmode() ceph: remove delay check logic from ceph_check_caps() ceph: consider inode's last read/write when calculating wanted caps ceph: always renew caps if mds_wanted is insufficient ceph: update dentry lease for async create ceph: attempt to do async create when possible ceph: cache layout in parent dir on first sync create ceph: add new MDS req field to hold delegated inode number ceph: decode interval_sets for delegated inos ceph: make ceph_fill_inode non-static ceph: perform asynchronous unlink if we have sufficient caps ceph: don't take refs to want mask unless we have all bits ...
