No probs, I added a note against this series. > Hope is all I got ;) There's also "tell Andrew stuff". It's very helpful! In the ordinary course of things I expect I'd have judged this series to be adequately tested and sufficiently well reviewed by sufficiently familiar names so I'd have moved it into mm-stable. But after learning of your concerns I've added a note and I moved the series to tail of mm-unstable where it will be easier to drop or defer should the need arise. If drop-or-defer is to be the decision then please let's make that as early as possible - we don't want non-merge-window material in there perturbing testing or causing integration issues.
