Interesting. My measurements showed much smaller differences (around 1-2% and smaller than the stdev). But I also saw that this difference was significantly bigger on older/less performant machines (which is not very surprising). Anyway, this series in itself won't solve the issues we currently have with deletion in nested ptrlist walking loops. Thanks for the numbers. -- Luc -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
