Are you talking about the kobj in your new struct cma_stat? That seems
like circular logic if so. I'm guessing Greg just wanted kobj methods
to be used *if* you are dealing with kobjects. That's a narrower point.

I can't imagine that he would have insisted on having additional
allocations just so that kobj freeing methods could be used. :)
