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.
