Went with the revert path on 6.12 as 137359b7 is a larger non-stable refactor that I'd rather not pull in just to satisfy a build prerequisite. 7cfcd01f33fc had two newer dependents (the duration_time fix and the python parse_events addition) that conflicted with reverting it alone, so I chained the reverts to keep the tree buildable. This re-introduces the perf cgroup UAF that c9ef786c0970 was fixing - if the perf folks would prefer to backport the missing prereqs (d2f3ecb0 + 137359b7) instead, happy to swap approaches. -- Thanks, Sasha
