Would you argue that memsw should be > per-root ? I'm fairly sure you can make about the same argument about use_hierarchy. There is a choice to make here and one is simpler than the other. I want the additional complexity justified by actual use cases which isn't too much to ask for especially when the complexity is something visible to userland. So let's please stop arguing semantics. If this is definitely necessary for some use cases, sure let's have it. If not, let's consider it later. I'll stop responding on "inherent differences." I don't think we'll get anywhere with that. Michal, Johannes, Kamezawa, what are your thoughts? Thanks. -- tejun -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
