One thing you could do is apply your patch and run your own workstation and other systems with it for a while, just to make sure no harm is done. Another thing is look through the archives on lkml and see which workloads benefit from the swap token and which workloads got harmed by it - then you can run both workloads on your system, and see whether your code switches the swap token on and off during the right workloads. -- "Debugging is twice as hard as writing the code in the first place.
