Ok, so that's not as bad as it looked. So, while it is still O(N), the

Do you mean N is the size of the loop? for_each_cpu_mask() loops
the number of CPUs times. It is not directly related to runqueue length.

Ok, I mistook it for a per-task loop.

Well, let me know if you think it's worth trying it out anyway.

I don't think this loop would be a bottle neck, but test by third person
is always valuable.

Thanks,
