    I suspect that the proper way to do this is to just make another gfp_flag,
    which is basically another hint to the mm layer that we're doing a multi-
    page allocation and that the MM layer should not try forever to handle it.

    In fact, that's independent of whether it is a multi-page allocation or
    not. It might be something like __GFP_SOFT - you could use it with single
    pages too.

    Thinking about it, we do have it already. It's called !__GFP_HIGH, and it
    used by all the GFP_USER allocations.
