I banged through nearly everything I could +2/+W this morning (mostly
stuff under the oslo or nova teams' remit). I saw very few issues and
no failing CIs so it was mostly a case of sanity checking and
approving.

If anyone is seeing issues with their "docs" target, feel free to give
me a shout (IRC: stephenfin) as we had to work through similar issues
in nova not too long ago. It's amazing where monkey patching will get
