But we do have the infrastructure for it in the kernel and NFS uses it. And it seems like a nice way to preserve user space backwards compatibility, without making the code to nasty. If we don't mind that bit of change that would make it harder to upgrade a kernel I don't mind not doing it. It just looks like a elegant way to handle that implementation change.
