So please stop increasing the size of cpu scheduler's code. Users
can't benefit anything from that. Also the interactivity problem of
scheduler is still exist though it improves a lot already.

It is better to stop bloating. Isn't ?

Also I m quite agree with Linus. The model of the scheduler now is
complex and there are many *UNNECESSARY* code. I CAN'T REALLY BENEFIT
ANYTHING. I just make my kernel with -j2 and the music is already
sucking![Intel E7500, 2.9GHZ, two core]. It can show that how the
interactivity problem is serious with mainline cpu scheduler. I know
it is not all the fault of mainline cpu scheduler but it is still a
big interactivity problem with it. [me think that Peter is proud of
his insane-box-supporting stuff]
