[PATCH 0/8] ceph: cap handling code fixes, cleanups and comments

[Jeff Layton <jlayton@kernel.org>]

I've been going over the cap handling code with an aim toward
simplifying the locking. There's one fix for a potential use-after-free
race in here. This also eliminates a number of __acquires and __releases
annotations by reorganizing the code, and adds some (hopefully helpful)
comments.

There should be no behavioral changes with this set.

Jeff Layton (8):
  ceph: reorganize __send_cap for less spinlock abuse
  ceph: split up __finish_cap_flush
  ceph: add comments for handle_cap_flush_ack logic
  ceph: don't release i_ceph_lock in handle_cap_trunc
  ceph: don't take i_ceph_lock in handle_cap_import
  ceph: document what protects i_dirty_item and i_flushing_item
  ceph: fix potential race in ceph_check_caps
  ceph: throw a warning if we destroy session with mutex still locked
