Subject: [PATCH v2 0/3] improvement of cpu burst

This patch set does a bit improvement for cpu burst feature including
1. Avoid burst associated statistic and calculation if the cpu.max.burst is
not set in the cgroup.
2. Limit the burst periods to 2 to avoid the quota 'stealing'

Changes in v2:
- Permitting 2 periods for burst.
- Add a separate patch to avoid burst stuff if the burst is not set at all.

Honglei Wang (3):
  sched/fair: avoid burst statistic if it's not set
  sched/fair: prevent cpu burst too many periods
