  ceph: defer flushing the capsnap if the Fb is used (2021-02-16 12:09:52 +0100)

----------------------------------------------------------------
With netfs helper library and fscache rework delayed, just a few cap
handling improvements to avoid grabbing mmap_lock in some code paths
and deal with capsnaps better and a mount option cleanup.

----------------------------------------------------------------
Ilya Dryomov (2):
      libceph: deprecate [no]cephx_require_signatures options
      libceph: remove osdtimeout option entirely

Jeff Layton (3):
      ceph: fix flush_snap logic after putting caps
      ceph: clean up inode work queueing
      ceph: allow queueing cap/snap handling after putting cap references
