Dietmar Eggemann 7552240c84 sched/fair: Return early from update_tg_cfs_load() if delta == 0 ... In case the _avg delta is 0 there is no need to update se's _avg (level n) nor cfs_rq's _avg (level n-1). These values stay the same. Since cfs_rq's _avg isn't changed, i.e. no load is propagated down, cfs_rq's _sum should stay the same as well. So bail out after se's _sum has been updated.
