First of all, thanx Con for this nice piece of code.

I've been trying in the last few days to backport this new scheduler to
a 2.6.18 kernel.  After a lot of efforts I have finally been able to
compile and run a RSDL patched 2.6.18.8 kernel on a x86_64 arch and
actually my test PC booted 2-3 seconds faster with it compared to a
vanilla 2.6.18.8 kernel.

This patch includes a few other patches from 2.6.19+ kernel:

PATCH 1:

co

PATCH 2:

co
mmit;h=3D08c183f31bdbb709f177f6d3110d5f288ea33933

PATCH 3:
The patch to get you from 0.26 to 0.28:
http://ck.kolivas.org/patches/staircase-deadline/2.6.20/sched-rsdl-0.26-
0.28.patch

There might also be other small pieces of code comming from a 2.6.19+
kernel.

Due to the project I'm currently working on, this will, in the next few
weeks, help me out comparing heavy loads on a Debian Sarge/Etch 32/64
platform.  Suggestions on benchmark tools would greatly be appreciated.

Duno if this will be helpfull for anybody but I tought it would be nice
to give it back to the lkml community.
