Jeff Layton	0efaa7e82f	locks: generic_delete_lease doesn't need a file_lock at all ... Ensure that it's OK to pass in a NULL file_lock double pointer on a F_UNLCK request and convert the vfs_setlease F_UNLCK callers to do just that. Finally, turn the BUG_ON in generic_setlease into a WARN_ON_ONCE with an error return. That's a problem we can handle without crashing the box if it occurs.

Jeff Layton	62af4f1f7d	locks: add some tracepoints in the lease handling code ... v2: add a __break_lease tracepoint for non-blocking case Recently, I needed these to help track down a softlockup when recalling a delegation, but they might be helpful in other situations as well.
