Yes, sorry it wasn't clear.

I still have no idea what's the "best" allocation method that we'll be
able to use as either a vmalloc buffer or split into a scatterlist, but
there's little point in worrying too much about it, so please go ahead.

If it's restricted to trans_fd and there's a chance we can make use of
it with (at least) virtio later I think everyone will be happy :)
