It looks like that commit only went back to 5.10. I also wonder why these commits were backported *at all*. On their own, they don't fix anything, but allowed further improvements that are not backport candidates either. Honestly, if I wanted these backported to stable, I'd have put a 'Cc: stable' tag. These patches don't even have a 'Fixes:' tag, for the same reason. M. -- Without deviation from the norm, progress is not possible.
