Subject[PATCH 2/3] sched/fair: trigger asym_packing during idle load balance
Date
newly idle load balance is not always triggered when a cpu becomes idle.
This prevent the scheduler to get a chance to migrate task for asym packing.
Enable active migration because of asym packing during idle load balance too.
