    smattering of others for the other patches. Given the review and
    feedback, I don't have a huge number of acked/reviewed-bys. I tried
    not to lose any after the first couple of revs, but I know I did some
    things wrong early on.

    I can prod some others who've contributed to add their tags, unless
    there is a good reason for them not too. I suspect it was just
    because of partial/drive-by reviewing, but I don't know.
