I think setting HZ much lower than 100 might break some drivers that do things like: timeout = jiffies + (HZ / 50); Not sure if any of the common drivers have this problem but be on the lookout for it if you want to try running w/ really low HZ. I suppose there should really be a "FRACTION_OF_SECOND()" macro or something that always returns >0 for specifying these really short delays. -Mitch - 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/ | ||||||||||||
