The tracepoint should change to have two different notifiers that represent one for coming and one for going (as ftrace does). The coming one should have a priority of 0 (or INT_MIN (all other notifiers dependent on this should have > 0) The going notifier should have a INT_MAX to run after all other tracepoint notifiers.
