SCHED_LOAD_SCALE/SHIFT are the fixed point mult/shift, and NICE_0_LOAD is the load of a nice-0 task. They happen to be the same by the choice that nice-0 has a load of 1 (the only natural choice given proportional weight and hyperboles etc..). But for the fixed point math we use SCHED_LOAD_* and only when we want to explicitly use the unit load we use NICE_0_LOAD (its only used 4-5 times or so). -- 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/
