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
