Patch looks fine to me, just need to figure out where it goes WRT to the
global rename. I don't really think linville would take the rename (he
probably wouldn't have taken it at any point last week either) so
whenever the rename patch goes in this one is fine to go on top of it.
Or, if you like we can try to push the non-renamed version of this patch
now as a cleanup and you can rebase the rename patch on top of this one.
