     - Fix regression in 'xino' feature detection

       I clumsily introduced this regression myself when working on another
       subsystem (fsnotify). Both the regression and the fix have almost no
       visible impact on users except for some kmsg prints.

     - Fix to performance regression in v6.12.

       This regression was reported by Google COS developers.

       It is not uncommon these days for the year-old mature LTS to get
       adopted by distros and get exposed to many new workloads. We made a
       sub-smart move of making a behavior change in v6.12 which could
       impact performance, without making it opt-in. Fixing this mistake
       retroactively, to be picked by LTS.
