I'm fully aware of this -> but it's useful for testing: if I'm running a
desktop that doesn't need to be secure, or else I'm testing a particular
pathway to see if it works with vserver period, that's when it's useful.

I'm currently running 2.6.6 with vs1.9.1. I assume this is what you
mean, unless you're talking about -mm?
I basically wanted to understand what new stuff is there exactly, and
grepping through the source code is difficult, as there's too many
different pathways, and I couldn't figure out what arguments to send to
vsched and the various other utilities to get them to use the new

So, not fully understanding the kernel scheduling mechanisms, what
parameters should I be using for cpu_mask, etc, to make sure that
particular vservers don't manage to hog the cpu?
