We need to update the below when do not need to enqueue entity because this is added for runnable_avg updating,

    update_load_avg(cfs_rq, se, UPDATE_TG);
    se_update_runnable(se);

Earlier version do not introduce the above to only update runnable_avg. Use one *for loop* is enough though. Please correct me if I am wrong.

Thanks a lot Tao! I'm not sure, I'm definitely not an expert in the scheduler. Will defer this one to Vincent / Peter / Phil / Ben. Cheers!
