All ordered request related stuff delegated to HLD. Midlayer now doens't deal with ordered setting or prepare_flush callback. sd.c updated to deal with blk_queue_ordered setting. Currently, ordered tag isn't used as SCSI midlayer cannot guarantee request ordering. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>
