I see. I wasn't aware that you're doing pull requests, but it isn't a
problem. It just means that you should probably do a pull request for
this one as well instead of expecting that I pick it up. But you can
have my Acked-by, if you like.
Should I ignore xen_disk patches from now on for the block branch and
assume that you pick them up?
