    There's no inherent reason why we cannot poison slab caches with a
    constructor. As a matter of fact SLAB does it which is probably why I
    got confused here. The only thing that needs to disable slab poisoning
    by design is SLAB_DESTROY_BY_RCU.

    But for SLUB, you're obviously right.

    Yeah, I know. Yet you're stuck with us. That's sad.
