Right, because otherwise people's systems would actually work.

But hey, as I said, following rules is more important, regardless of
what the rules are, and why they are there. The rules that actually
triggered this issue in v3.3.1, as this is not in v3.3.

You could just accept that the patch should have never landed in
v3.3.1 in the first place, but it's much easier to arbitrarily keep
stacking patches without thinking too much about them.

I guess I'll better use Linus's releases for now and go to v3.3.
