    Have you at all followed the discussion about the people who asked for
    cross-CPU ordering? They wanted not timestamps at all, but global atomic
    counter updates. Which is very reasonable, if timestamps don't work (and
    jiffies certainly doesn't, especially in a NOHZ environment).

    IOW, my whole argument is that what tracers want is _not_ the same thing
    as what "sched_clock()" wants.
