Bugfixes are *early* -rc candidates. Regression fixes are *late* -rc
candidates, at least that seems to be the policy Linus currently
implements. -stable seems to use slightly less strict criteria (the
whole point is that -final needs to be a stabilization point, backported
fixes/drivers can then come onto a stable base) which is why you seem
some patches which are "straight to .1".

OK. You can check with -stable if they want to take the backport post-.33.
