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 2~5 are the bug fixing.

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.
