Jens, not sure if you saw the whole thread. This has triggered bad page
state errors, and also corrupted a btrfs list. It hurts me to say, but it
might not actually be your fault.

Where is that thread, and what is the "this" that triggers problems?

Looking at the "->mq_list" users, I'm not seeing any changes there in
the last year or so. So I don't think it's the list itself.

Seems to be the whole thing:

My guess is xattr, but I don't have a good reason for that.
