It seems that we are not updating is_idle when we find an idle CPU with pick_cpu(), causing unnecessary rescheduling events when select_cpu() is called.
To resolve this, ensure that the is_idle state is correctly set. Additionally, always ensure that the task is dispatched to the local DSQ immediately upon finding (and reserving) an idle CPU.
