Subject: [PATCH v2 0/3] small fix for scale usage

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

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
