This patchset can be used, but causes burst waking benchmark aim9 drop 5~7% on my 2 sockets machine. The reason is too light runnable load in early stage of waked tasks cause imbalance in balancing.
So, it is immature and just a reference for guys who want to go gurther.
Thanks! Alex
[PATCH 1/4] sched: update cpu load after task_tick. [PATCH 2/4] sched: compute runnable load avg in cpu_load and cpu_avg_load_per_task [PATCH 3/4] sched: consider runnable load average in move_tasks [PATCH 4/4] sched: consider runnable load average in effective_load
