Thanks for your review.
I agree that the submit message is a bit misleading, what this patch do is just
avoiding search for least_loaded_cpu
in non-idle cpus.
sched:add check of shallowest_idle_cpu before search for least_loaded_cpu
Idle cpu is idler than non-idle cpu, so we needn't search for
least_loaded_cpu
after we have found an idle cpu.
what about this?
Thanks,
