Which reminds me... One spirited side discussion at Santa Fe involved RCU's rcu_node tree and CPU numbering. Several people insisted that RCU should remap CPU numbers to allow for interesting CPU-numbering schemes. I resisted this added complexity rather strenuously, but eventually said that I would consider adding such complexity if someone provided me with valid system-level performance data showing a need for this sort of remapping. I haven't heard anything since, so I figured that I should follow up. How are things going collecting this data? Thanx, Paul
