Ok, so that's not as bad as it looked. So, while it is still O(N), the
fact that it is O(N/HZ) makes this not a problem until you get to
possibly impractical levels of runqueue length.
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,
