The V2 seems stable, but sometimes tests might produce false positives, mostly related to system configurations or system overload. We digged quite a lot into it in the past years and we ended up with a solution which "good enough" for regression testing, supporting both v1 and v2. Also, kselftests already cover many cgroup testing scenarios and we are not actively investing time on it. But you and others are welcome to try implementing something, if you think this can be helpful. My biggest concern is the code quality. cgroups can be a complex beast to handle with LTP API, which are made supporting v1 and v2. If you are willing to implement new tests, please consider test cases scenarios that are not implemented in LTP and kselftests. Those are the most valuable at the moment.
