Ok, didn't even get around to push it out before I dropped it again on
Ville's request. Please always Cc: everyone who discussed previous
versions of a patch series to get their attention. And please include all
such Cc: lines in the commit messages, so I know whom to ping on irc in
case of doubt first.
And a minor bikeshed: I prefer if there's a per-patch changelog somewhere,
not just in the cover letter. Although I guess doesn't apply here since
most patches are new/completely different.
Thanks, Daniel
