That's pretty much a blanko argument for throwing everything into the
kernel. What's next, throwing your jvm into the kernel because you like
some kernel helpers?

We've been through this a few times - there is no reason why a tool
using the KVM ioctls should be considered close to the kernel - all
other users get away just fine staying out of tree, and that has
helped to keep the ABI stable.

This sounds more like you should create a libkernelutil with useful
data structures we use in the kernel for userspace programs. I'd love
to use that for a few projects, btw.
