Can we keep Darshak's authorship? We usually change the author if we feel that
we made a significant change to what was originally published.

If it's just about cosmetics, cleaning or rebase, you can specify what you did
after the author's S-o-b tag and then add your S-o-b, as you did above.

The patch looks good.

Cheers,
