The way we expect get_user_pages() to be used is that the kernel will use
get_user_pages() once per application I/O request.

Are you saying that the mapping obtained by get_user_pages() is valid only within the context of the IOCtl call? That once the driver returns from the IOCtl, the mapping should no longer be used?
