    Thing is, lots of people are enabling CONFIG_DEBUG_VM, but a smaller
    number of people will enable CONFIG_DEBUG_VM_POISON. Less coverage.

    Defaulting to y if CONFIG_DEBUG_VM might help, but if people do `make
    oldconfig' when CONFIG_DEBUG_VM=n, their CONFIG_DEBUG_VM_POISON will
    get set to `n' and will remain that way when they set CONFIG_DEBUG_VM
    again.
