Have you looked at Patch 9 of this series:

https://lore.kernel.org/stable/2023070416-wow-phrasing-b92c@gregkh/T/#m12068530e846ac8b9668bd83941d82ec3f22ac15

Looks very much related, it also has a note on Backporting.
As I think it could be related, I am sharing this.(But haven't tested 
anything)

Thanks,
Harshit
