  locks: update Locking documentation to clarify fl_release_private behavior (2014-08-14 10:08:20 -0400)

----------------------------------------------------------------
File locking related bugfixes for v3.17 (pile #2)

Hi Linus!

Most of these patches are to fix a long-standing regression that crept
in when the BKL was removed from the file-locking code. The code was
converted to use a conventional spinlock, but some fl_release_private
ops can block and you can end up sleeping inside the lock.

There's also a patch to make /proc/locks show delegations as "DELEG".

----------------------------------------------------------------
Jeff Layton (6):
      locks: show delegations as "DELEG" in /proc/locks
      locks: don't call locks_release_private from locks_copy_lock
      locks: don't reuse file_lock in __posix_lock_file
      locks: defer freeing locks in locks_delete_lock until after i_lock has been dropped
      locks: move locks_free_lock calls in do_fcntl_add_lease outside spinlock
      locks: update Locking documentation to clarify fl_release_private behavior
