Is this fix needed in 2.6.26.x?  2.6.25.x?

whoa, what's all that about?

Patches can only have one Author: in git, and we indicate that in
emails by putting a From: line right at the top of the changelog. 
(Additional credits can and should be mentioned in the changelog text
of course).  When that From: line is missing we take the authorship
info from the email headers.

So according to the above, this patch has three authors.  Geeze, even I
can type faster than that!

Who wrote it?
