Thanks Stephen.  I had been forewarned about this by Selvin and I
instructed him to send me a fixup patch that would resolve the issue.  I
would apply it to my tree before merging with Linus.  He just hadn't
time to send it yet.  Your patch is sufficient as well, so I may just
pull it in.  Thanks again.
