original kernel 2.6 and Arjan's differences

[Michal Zeravik]

Hi,

what are difference between Arjan's 2.6 kernel
and original version from Linus?
Old 2.4 redhat kernels have been hardly patched
to get new drivers, more security, preemptive,
low latency, capabilities, nptl and so on.
What is the situation in 2.6 kernel?
I'm running several audio apps which need
low latency and caps on my desktop.
Preemptive is better to not use in 2.6 as I googled.
