The above code, before your change, had the affect that if mpol_copy()
failed, then the cpusets that were just setup by the cpuset_fork()
call were undone by a cpuset_exit() call.
>From what I can tell, after your change, this is no longer done,
and a failed mpol_copy will leave cpusets in an incorrect state.
Am I missing something?
