437 The wait_lock of the mutex is taken since the slow path of unlocking the
449 wait_lock, which this code currently holds. So setting the "Has Waiters" flag
477 Since the wait_lock was taken at the entry of the slow lock, we can safely
486 (or deadlock checking is on), we unlock the wait_lock of the mutex and go ahead
527 The first thing done in the slow unlock path is to take the wait_lock of the
