Perhaps someone who knows CKRM better than I can explain why the CKRM
version in some SuSE releases based on 2.6.5 kernels has substantial
code and some large ifdef's in sched.c, but the CKRM in *-mm doesn't.
Or perhaps I'm confused.  There's a good chance that this represents
ongoing improvements that CKRM is making to reduce their footprint
in core kernel code.  Or perhaps there is a more sophisticated cpu
controller in the SuSE kernel.

As there is NO CKRM cpu controller in 2.6.13-rc3-mm1 (that I can see) the one in 2.6.5 is certainly more sophisticated :-). So the reason that the considerable mangling of sched.c evident in SuSE's 2.6.5 kernel source is not present is that the cpu controller is not included in these patches.

I imagine that the cpu controller is missing from this version of CKRM because the bugs introduced to the cpu controller during upgrading from 2.6.5 to 2.6.10 version have not yet been resolved.
