Subject[PATCH 3.16 106/357] locks: pass correct "before" pointer to locks_unlink_lock in generic_add_lease
Date
3.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jeff Layton <jlayton@primarydata.com>

commit e0b760ff71be168d4e623f7c3612e98902ab93e9 upstream.

The argument to locks_unlink_lock can't be just any pointer to a
pointer. It must be a pointer to the fl_next field in the previous
lock in the list.
