Linus Torvalds fcc95f0640 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: 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
