I would have expected this in the previous patch that introduced that lot. Including a few words on how/why the cpu_capacity is a 'good' approximation etc.. > Finally, the sched_group->sched_group_capacity->capacity_orig has been removed > because it's more used during load balance. That sentence is a contradiction, I expect there's a negative gone missing someplace. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
