  huh.  i believe you're correct.  i'll take a closer look but i still
get this feeling that there's something ... messy about that API.
case in point:  kfifo_in_rec() is *not* being exported, but a routine
that it invokes -- __kfifo_in_generic() -- *is* being exported.
doesn't that just seem a bit backwards?

  anyway, off to the gym to bike and see which duke team shows up for
