Not a matter of procedure, but it would have been easy to avoid.
I take at least part of the blame here because I did not follow up
with you to make sure that you merge the infrastructure into your tree.

That was the original idea, but the restart handler was way more successful
that I thought it would or could be, so things got pulled in a bit.

Anyway, I tend to agree - there are now several other build failures in
Linus' tree which it inherited from linux-next. I consider those worse,
especially since the majority if not all of those problems were known
from -next but ignored. Wonder what the value of -next is if people
don't care if it builds or not :-(.

But then Linus ignored my pull request (so far), so maybe I did manage to
upset him ;-).
