The idea is to make them tunable so that interested parties can determine the best settings without having to rebuild the kernel. Once that's all done we can remove the tunable (because it's debugfs) and hard-wire the optimised constants. But I don't think anyone has done this tuning work yet. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
