If anyone has any objections, please let me know. ------------------ From: majianpeng commit 73d9f7eef3d98c3920e144797cc1894c6b005a1e upstream. For nofail == false request, if __map_request failed, the caller does cleanup work, like releasing the relative pages. It doesn't make any sense to retry this request.
