I think that's inaccurate and there are plenty of folks that have that technical skill and background. The scheduler code isn't a deep mystery and there are plenty of good kernel hackers out here across many communities. Ingo isn't the only person on this planet to have deep scheduler knowledge. Priority heaps are not new and Solaris has had a pluggable scheduler framework for years. Con's characterization is something that I'm more prone to believe about how Linux kernel development works versus your view. I think it's a great shame to have folks like Bill Irwin and Con to have waste time trying to do something right only to have their ideas attack, then copied and held as the solution for this kind of technical problem as complete reversal of technical opinion as it suits a moment. This is just wrong in so many ways. It outlines the problems with Linux kernel development and questionable elistism regarding ownership of certain sections of the kernel code. I call it "churn squat" and instances like this only support that view which I would rather it be completely wrong and inaccurate instead. bill
