Yeah, the above actually looks really good to me - I like the naming
here, and the use looks very logical to me.

Of course, maybe once I see the patches that use this I go "uhh", but
at least for now I think you've hit on a rather legible syntax.

I'm still a bit unsure of the "no_free_ptr(p)" naming, but at least
it's pretty clear about what it does.

So my only worry is that it's not pretty and to the point like your
"__free(kfree)" syntax.

But it feels workable and not misleading, so unless somebody can come
up with a better name, I think it's ok.
