Right, fortunately it doesn't appear that the conflicts are too hard to resolve. It looks like sch_redirect_xmit() will need to be resolved with an additional check to test if the qdisc lock is needed. Then assuming my reading is correct validate_xmit_xfrm(), xfrm_dev_resume(), and xfrm_dev_backlog() can run without qdisc lock already.
