It gives us the opportunity to change the default behavior for most users at the point when we'll be sure that new behavior is better; but at the same time we'll save full compatibility on the kernel level. With growing popularity of memory cgroups, I don't think that hiding this functionality with a boot option makes any sense. It's just not this type of feature, that should be hidden. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
