    SubjectRe: [PATCH v3 01/11] block: make generic_make_request handle arbitrarily sized bios
    This needs the patch below for the blk-mq case with multiple queues.

    Also I wonder why we really want to push this below ->make_request.
    Moving it just outside ->make_request would make the callchain more
    obvious and avoid the recursion into the driver.
