The low latency (by Andrew Morton) and preemptible kernel patch (by Robert Love) enhancements mentioned in the article do not include the O(1) (realtime?) scheduler. I understand how the first 2 are supposed to work now (after 6-8 straight hours of reading up on the subject matter) in a high level way, but can someone point me to more info about the Ingo Molnar's O(1) scheduler or explain how it works? As I understand the low latency and preemptible kernel patches are supposed to be somehow combined. The O(1) scheduler is a separate matter though. _ Philippine Linux Users Group.
