The "with" here has been quite confusing, and I realized that you
mean the subject domain rather than the actor one only after
having gone through quite some parts of the patch. For a patch
this size, a little more of a description (and the original motivation)
would have helped.

Wrt motivation: Why does this need enforcing in the kernel at all?
Doesn't XSM_DM_PRIV mode deal specifically with what you're
trying to do here? Or else I guess I really need some better
explanation of what this is about.
