This is a collection of rather loosely coupled small changes to the cfs scheduler related to:
Comments (patch 1/7, 2/7):
Remove/fix some outdated comments related to 'power aware scheduling' and smpnice.
Load-balance (patch 3/7 - 5/7):
Change unit of load_above_capacity in calculate_imbalance() from [load] to [load/capacity]
Refactoring logic in fix_small_imbalance() and remove cpu_avg_load_per_task().
Misc (patch 6/7, 7/7):
Reorder update_sd_lb_stats() and use group_cfs_rq(se) throughout fair.c.
Test-results:
IVB-EP (2*10*2):
perf stat --null --repeat 10 -- perf bench sched messaging -g 50 -l 5000
Before: After: 4.784556741 ( +- 0.99% ) 4.760953662 ( +- 0.47% )
Juno (ARM64) (2B/4l*1):
perf stat --null --repeat 10 -- perf bench sched messaging -g 20 -l 500
Before: After: 7.227439638 ( +- 0.50% ) 7.151685712 ( +- 0.64% )
