One bad fixes tag here, but good enough.
Hopefully the big RCU-ifying patch won't blow up :)

Weird, I'd run verify-fixes and it didn't show up anything. As for the
RCU changes, yeah I was considering pulling it out but since it is a
single commit with no other dependencies we can always just revert it
if it causes problems.

I think it works by checking the git database. If the commit exists 
in your git it will not complain. So you need a somewhat pristine
repo instance to avoid false negatives.
