Sure, I'd be happy to do that for future stuff.  I don't see this email
address mentioned anywhere in the kernel tree.  It seems like this is
useful information that should go in either MAINTAINERS or better yet
Documentation/SubmittingPatches for it to be discoverable by future
patch-senders -- and somewhere that I can look it up easily later.  :)
