I didn't mark this for stable because I expect things to still change
- particularly the WARN_ON_ONCE() should be removed before final 5.4,
I just wanted to see if anybody could trigger it with testing etc.

(At least syzbot did trigger it).

If you do want to take it, take it without the WARN_ON_ONCE() calls
and note that in the commit message..
