I hate to go all bureaucratic, but there's quite a lot missing here, and it's rather important, to some. It's all about taking care of people who are using kernels prior to 7.2 (or 7.1). - Link: to Brian's reports? - Description of user-visible runtime effects of the bugs? - Fixes: targets? - Decision on whether we should backport the fixes into earlier kernels? Anyway, I'll queue these in mm-new, but please give some thought to the above? Also, AI review didn't find anything to complain about with these changes, but it might have found a pre-existing issue: https://sashiko.dev/#/patchset/20260525044639.1888561-1-senozhatsky@chromium.org Thanks.
