I like the option, but 0 is not a good default. Make it 1 or something. Perhaps a better heuristic would be percent < threshold || samples < sample-threshold with sample-threshold being several hundred at least. A very small number of hits on something is usually quite much useless, unless your original event was extremly rare in the beginning (but then it's unclear if the profile is any useful) -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
