good idea.

I'm glad you didn't removed the rv-b tags. The review process that
happened so far was very productive. Let's keep the right credits in place and
take extra care when merging to dinq. Let's only merge what we are confident
that review is still valid or ask for re-reviews and extra acks.

One idea that I heard this morning was to use on internal some custom tag
like "Internally-Reviewed-by:" but I don't like this idea of adding custom
tags and I trust our commiters to differentiate between valid internal reviews
and risky ones. Agree?

Thoughts?
