    The per-process mode works fine after moving the trace point to be after:

    perf_event_task_sched_in(prev, current);

    App developers using this feature here say they're fine not having the
    block vs sleep distinction because they intend to use it with "-g" and
    the callstack makes it obvious which one it was.

    If we really need this info, we should be able to derive it in user
    space via perf inject.
