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. Linus
