Patchset looks good to me now. Thanks!
I'll push it tonight.

As for your change in MAINTAINERS, the discussion is still
ongoing, so I'll push it with the condition that it's just
there to let submitters know who to ping, rather than
requesting push access. If you'd like push access, just
send a request on the ML.
