        lu_ref fields ->l_reference and ->lr_reference are added to ldlm_lock
        and ldlm_resource. LDLM interface has to be changed, because code that
        releases a reference on a lock, has to "know" what reference this is.
        In the most frequent case

        ldlm_handle2lock()) is released, LDLM_LOCK_RELEASE() has to be called

        for proper use. On the other hand, it was very instrumental in finding
