Right -- but it's not your job to make sure the migration stuff is
properly addressed; it's Wei and Ian's job. Wei's R-b was a statement
from him that the code was good; when Andy questioned that, I think it
was then *Wei's* job to address the question, not yours or Andy's (or
even Olaf's). If Wei says, "I've considered Andy's objections and I
think the patch is fine as-is", then it can be checked in (given a
reasonable amount of time for Andy to respond); and Wei can own whatever
consequences there are.
