    usbfs could copy the user buffer to a bunch of non-contiguous pages, and
    then fire those off in an urb using the scatter-gather stuff. [Rather than,
    as now, allocating a bunch of contiguous pages using kmalloc]. That would
    probably make it possible to use much much bigger user-space buffers. Plus
    the code looks rather easy to write.
