Peter,
What's your opinion about this patchset? Are there sth missing? :)
The patchset git tree is here:
git@github.com:alexshi/power-scheduling.git runnablelb
> [patch v7 1/8] Revert "sched: Introduce temporary FAIR_GROUP_SCHED
> [patch v7 2/8] sched: move few runnable tg variables into CONFIG_SMP

Patch 2~5 are the bug fixing.
> [patch v7 6/8] sched: compute runnable load avg in cpu_load and
> [patch v7 7/8] sched: consider runnable load average in move_tasks
Only patch 6th/7th enable the runnable load in load balance.
> [patch v7 8/8] sched: remove blocked_load_avg in tg
According to test, the 8th patch has performance gain.
