It needs a 1024, it might just have been the 1024 ns we use a period instead of the scale unit though. The LOAD_AVG_MAX is the number where adding a next element to the series doesn't change the result anymore, so scaling it up will allow more significant elements to the series before we bottom out, which is the _N thing. -- 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/
