Good point.

How about also adding this check (NULL mm and struct subset cpus)
to sched_setaffinity?

Granted, this pair of checks, in cpusets and sched_setaffinity,
is getting to be a little more work than the PF_* flag.

I guess one question would be how hard we want to work to avoid
consuming another PF_* flag.  I thought they were scarce, but I
might be wrong.
