[RFC 38/60] cosched: Skip updates on non-CPU runqueues in cfs_rq_util_change()

2018-09-07 Thread Jan H . Schönherr
The function cfs_rq_util_change() notifies frequency governors of utilization changes, so that they can be scheduler driven. This is coupled to per CPU runqueue statistics. So, don't do anything when called for non-CPU runqueues. Signed-off-by: Jan H. Schönherr --- kernel/sched/fair.c | 11
