If there is now an assumption that util_avg may be used directly as a capacity value, should it be changed to SCHED_CAPACITY_SHIFT? These are equal right now, not sure if they will always be or if they can be combined. > + * capacity_orig is the cpu_capacity available at * the highest frequency spurious * thanks, Steve -- 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/
