[PATCH v6 00/13] ceph: async directory operations support

[Jeff Layton <jlayton@kernel.org>]

v6: move handling of CEPH_I_ASYNC_CREATE from __send_cap into callers
    also issue ceph_mdsc_release_dir_caps() in complete_request
    properly handle -EJUKEBOX return in async callbacks
    
I previously pulled the async unlink patch from ceph-client/testing, so
this set includes a revised version of that as well, and orders it
some other changes.

The main change from v5 is to rework the callers of __send_cap to either
skip sending or wait if the create reply hasn't come in yet.

We may not actually need patch #7 here. Zheng had that delta in one
of the earlier patches, but I'm not sure it's really needed now. It
may make sense to just take it on its own merits though.

Jeff Layton (12):
  ceph: make kick_flushing_inode_caps non-static
  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

Yan, Zheng (1):
  ceph: don't take refs to want mask unless we have all bits
