Hi all,
Has anyone tried to patch CKRM to linux-2.6.20 ?
I need it so that I can run CKRM in UML mode, which is very stable in
linux-2.6.20, and very unstable in linux-2.6.18 :-(

I tried to port CKRM in linux-2.6.20 vanilla kernel, by doing similar
modification's as there were in linux-2.6.18 CKRM patched kernel.

I had some problems in doing modifications in "kernel/sched.c" as
quite a few things are changed there.

Unfortunately, after modifications, kernel-2.6.20 is not compiling,
and giving error's at unexpected places where I have not done any
modifications.
I am getting compilation errors in "arch/i386/kernel/asm-offsets.c"

Please, let me know if it is possible to patch 2.6.20 with CKRM patch,
and all steps that I need to take in order to do so.

I got following errors, from which I was not able to make any sense.
