If I recall correctly, I only offered review comments on this patch,
I wasn't directly involved in writing it, or in the submission
process, so you don't need to have my signed-off-by here.  It's also
generally considered impolite to add someone's signed-off-by without
asking for permission. I don't mind either way, but you don't need
my tag since you wrote the patch, I only provided feedback.

Thanks,
~Ryan
