My guess would be for the case where sched_preempt_enable_no_resched()
is followed some time later by cond_resched().

I might hope not.. preempt_enable_no_resched() is nasty and you're likely to be
hit with a frozen fish of sorts by tglx if you try to use it ;-)

I will stick with my guess, though I agree that if I am correct,
this situation almost certainly predates tglx's Linux-related use of
frozen fish as projectile weapons.  ;-)
