I also wonder why these commits were backported *at all*. On their
own, they don't fix anything, but allowed further improvements that
are not backport candidates either.

Honestly, if I wanted these backported to stable, I'd have put a 'Cc:
stable' tag. These patches don't even have a 'Fixes:' tag, for the
same reason.
