My flags only make sense with HUGETLBFS. So they can never coexist anyways. So there is no reason to not overlap. So I think the original patch is ok and doesn't need any change at all. Sorry guys, if you really want to invent new syscalls please do it yourself. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
