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 from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
