Nope, the most visible thing are some new annoying warnings, that seem
absolutely broken.

At the very minimum, that WARN_ON(1) should be a WARN_ON_ONCE() or
something like that. Because showing it over an dover again is not
helpful.

Added the people who signed off on the changes to the affected files,
since they hopefully know why this happens and can fix it..
