I don't think we had h_nr_running back when I frobbed this last. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

The computation of avg_load and avg_load_per_task should only takes into account the number of cfs tasks. The non cfs task are already taken into account by decreasing the cpu's capacity (cpu_power) and they will be tracked in the CPU's utilization (group_activity) of the next patches Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org> --- kernel/sched/fair.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
