Yeah, that's sad.

I think the '__free(kfree)' thing should *only* be used in the form

        struct obj *p __free(kfree) = kmalloc(...);

which is what our docs mention. Anything else is simply buggy.

But how do we *notice* this?

I do want to stress how I was unhappy about this conversion to begin with

    https://lore.kernel.org/lkml/CAHk-=wigZt6kVkY0HU1j_LJ5H1KzwPiYnwwk6CbqXqT=sGenjg@xxxxxxxxxxxxxx/

but I reacted to the wrong issue.

This stuff needs to be done *way* more carefully.
