Hi stable mantainers,
[note I'm CC'ing here Guillaume, Yu and Christoph]
In Debian we were affected for a while by https://bugs.debian.org/1086175 which we found to be reported by Guillaume as https://lore.kernel.org/all/Z7Y0SURoA8xwg7vn@bender.morinfr.org/ .
The issue went in fact back to 6.0. The fix was applied upstream and then backported to 6.14.2 already. Can you backport it please as well down to the other stable series, at least back to 6.12.y it goes with applying (and unless I miss something fixes the issue, we cherry-picked the commit for Debian trixie and our 6.12.y kernel in advance already).
For going back to 6.1.y it seems it won't apply cleanly, You, Christoph might you be available to look into it to make this possible?
Regards, Salvatore
