Yeah, that's the part that ends up being really painful to backport (with all the subsequent fixes too), so the 4.14 people would prefer to avoid it.
But I think that if it's a "requires dax pmem and ptrace on top", it may simply be a non-issue for those users. Although who knows - maybe that ends up being a real issue on Android..
