If you're ok with the patch, I think it should go into 5.14 - and be
marked for stable.

The locking right now is very wrong, and causes syzbot warnings and
probably keeps people from finding other things.

And we can't just revert the incorrect locking change, because it was
a security issue.

So this should go in the current release cycle. I agree it's a bit
scary - not because I think the patch is all that complicated, but
because this area has clearly had issues and is subtle - but I'd
rather do it asap and get reports on it early than delay it further.
