> According to the data, the length of the most copies is >=128. Thanks for the data. Large is easier to optimize than small, that's good. Could you also measure how many memsets need the backwards copy? (should be easy to add) If the number is small that needs backwards then the easiest fix would be to simply call the normal memcpy in the forward case. That is for backward could also use a string instruction copy of course, just have to set the direction flag. That would be a very small code change. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
