But more importantly: once we introduce these rewrite into LTP, who's gonna maintain them? We already had an example of kselftests tests rewritten in memcontrol02/03 and (as you can see from the history of this ML) these are causing lots of issues and false positives. Mostly, unfixable. What I personally see, it's a duplication of code between projects and even if LTP core library has a "better" cgroup support than ksefltests, still, there's a risk we are going to maintain something that is breaking and someone has to figure our why/what needs a fix. kselftests almost come "for free" and many people are already using them all around the world to test cgroups. For this reason, I'm against adding these tests into LTP, unless there's a valid maintenance plan for the future.
