FWIW you are mixing up things. Linus does not handle the stable
kernels. He does the release candidates and the initial version of
every kernel release. The stable releases are handled by the stable
maintainers. Linus only said, that he does not want to get these
kind of fixes during late -rc phase. That makes sense considering
fixes also have a chance of introducing regressions.

But if patches end up in a pull request for an -rc kernel or in the
pull request for the next merge window depends on the maintainer
applying the patch (i.e. Heiko). The maintainer can queue a patch
with all those tags into the normal for-next queue targeting the
following merge window. This results in the patch being in
linux-next for a while, then being added to the master branch during
a merge window and then being added to the stable trees (as stable
only picks patches that are in mainline).

The maintainer can also merge a patch to the queue for -rc kernels
without the Cc stable. That is exactly what happens for a regression
from a normal patch in the merge window, since the affected patch
wouldn't be in any stable kernel.

TLDR: The Cc stable tag has nothing to do with Linus.
