  ceph: fix snapshot directory timestamps (2020-03-30 12:42:43 +0200)

----------------------------------------------------------------
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)

----------------------------------------------------------------
Andreas Gruenbacher (1):
      ceph: switch to page_mkwrite_check_truncate in ceph_page_mkwrite

Gustavo A. R. Silva (1):
      ceph: replace zero-length array with flexible-array member

Hannes Reinecke (2):
      rbd: kill img_request kref
      rbd: enable multiple blk-mq queues

Ilya Dryomov (7):
      libceph: drop CEPH_DEFINE_SHOW_FUNC
      rbd: remove barriers from img_request_layered_{set,clear,test}()
      rbd: get rid of img_request_layered_clear()
      rbd: acquire header_rwsem just once in rbd_queue_workfn()
      rbd: embed image request in blk-mq pdu
      libceph: simplify ceph_monc_handle_map()
      libceph: directly skip to the end of redirect reply

Jeff Layton (18):
      ceph: register MDS request with dir inode from the start
      ceph: add refcounting for Fx caps
      ceph: don't ClearPageChecked in ceph_invalidatepage()
      ceph: reorganize fields in ceph_mds_request

      ceph: add flag to designate that a request is asynchronous
      ceph: track primary dentry link
      ceph: add infrastructure for waiting for async create to complete
      ceph: make __take_cap_refs non-static
      ceph: cap tracking for async directory operations
      ceph: perform asynchronous unlink if we have sufficient caps
      ceph: make ceph_fill_inode non-static
      ceph: decode interval_sets for delegated inos
      ceph: add new MDS req field to hold delegated inode number
      ceph: cache layout in parent dir on first sync create
      ceph: attempt to do async create when possible

Luis Henriques (2):
      ceph: re-org copy_file_range and fix some error paths
      ceph: fix snapshot directory timestamps

Qiujun Huang (1):
      ceph: return ceph_mdsc_do_request() errors from __get_parent()

Xiubo Li (3):
      ceph: move ceph_osdc_{read,write}pages to ceph.ko
      ceph: fix description of some mount options
      ceph: return ETIMEDOUT errno to userland when request timed out

Yan, Zheng (14):
      ceph: check inode type for CEPH_CAP_FILE_{CACHE,RD,REXTEND,LAZYIO}
      ceph: check if file lock exists before sending unlock request
      ceph: don't take refs to want mask unless we have all bits
      ceph: update dentry lease for async create
      ceph: always renew caps if mds_wanted is insufficient
      ceph: consider inode's last read/write when calculating wanted caps
      ceph: remove delay check logic from ceph_check_caps()
      ceph: simplify calling of ceph_get_fmode()
      ceph: update i_requested_max_size only when sending cap msg to auth mds
      ceph: check all mds' caps after page writeback
      ceph: cleanup return error of try_get_cap_refs()
      ceph: request new max size only when there is auth cap
      ceph: don't skip updating wanted caps when cap is stale
      ceph: wait for async creating inode before requesting new max size
