Here are three patches which correct scale usage in both fix_small_imbalance
and update_sg_lb_stats.
And give out comment over when fix_small_imbalance would cause load change.
V2: fix scale usage for update_sg_lb_stats
V3: fix scale problem in comparing sds->busiest_load_per_task
and sds->avg_load when there is not balanced group inside the domain
Lei Wen (3):
sched: reduce calculation effort in fix_small_imbalance
sched: scale the busy and this queue's per-task load before compare
sched: scale cpu load for judgment of group imbalance
