You can keep only the for_each_online_cpu() loop and remove the other
one. And in that one also, you don't have to do this for every cpu...
something like this will help you...
cpus_processed = NULL;
for_each_online_cpu(cpu) {
if cpu-is-present-in cpus_processed
continue;
cpu-set-mask(cpus_processed, policy->cpus);
}
Syntax is poor, please choose the correct one.
