I doubt that _any_ of the regressions that are user-visible are scheduler-related. They all tend to be disk IO issues (bad scheduling or just plain bad drivers), and then sometimes just VM misbehaviour. People are looking at all these RT patches, when the thing is that most nobody will ever be able to tell the difference between 10us and 1ms latencies unless it causes a skip in audio. Linus
