To clarify: "incorrect" here means in the stable kernel, i.e. not the
backported patch.

Andrew: in the past, I was quite conservative in what I would mark as
Cc: stable for Rust, but after discussing a few past cases with the
current stable kernel team and/or being requested to add the tag, I am
nowadays way more optimistic in tagging. Some backports would not pass
the stated rules in principle, but they still wanted them.

For instance, I tag even Clippy cleanups (so far, since it seems
doable to keep it clean with the amount of code we have).
Nevertheless, I still skip the tag when I really feel there is no
point, and let their scripts pick them up if they really, really want
them.

For this particular case, since we support several compiler versions
nowadays, I would have just tagged it if it had went through my
branch. There is also little risk whether it gets backported or not.

I hope that gives some context.

Cheers,
Miguel
