Nack:
Vincent is correct, rq->avg is supposed to be the average time that an
rq is runnable; this includes (for example) SCHED_RT.
It's intended to be more useful as a hint towards something like a
power governor which wants to know how busy the CPU is in general.

Vincent is correct, rq-avg is supposed to be the average time that an
rq is runnable; this includes (for example) SCHED_RT.
It's intended to be more useful as a hint towards something like a
power governor which wants to know how busy the CPU is in general.

Old function count the runnable avg on rq's nr_running even there is
only rt task in rq. That is incorrect, so correct it to cfs_rq's
nr_running.

Old function count the runnable avg on rq's nr_running even there is
only rt task in rq. That is incorrect, so correct it to cfs_rq's
nr_running.
