I have mixed feelings about that. One on side, I'd love to merge the scalability patches in mainline. We've had a significant number of bugs in this area in the past, and it seems a shame that we all have to fix them independently because we deviate from mainline. On the other hand, 2.4 is pretty much closed. There wont be a big number of new distro 2.4 kernels. Had you asked me 6 months ago I probably would have advocated merging them, but right now I think it's a waste of time. -- Jens Axboe
