I don't much care. 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.
