 used to indicate the whole sequence of performing barrier requests
 including draining and flushing.

-The only difference between the two functions is whether or not the

 @q			: the queue in question
 @ordered		: the ordered mode the driver/device supports
 @prepare_flush_fn	: this function should prepare @rq such that it
 			  flushes cache to physical medium when executed
-@gfp_mask		: gfp_mask used when allocating data structures
-			  for ordered processing
 
 For example, SCSI disk driver's prepare_flush_fn looks like the
 following.
 
-static void sd_prepare_flush(request_queue_t *q, struct request *rq)
+static void sd_prepare_flush(struct request_queue *q, struct request *rq)

 	memset(rq->cmd, 0, sizeof(rq->cmd));

 	rq->timeout = SD_TIMEOUT;
 	rq->cmd[0] = SYNCHRONIZE_CACHE;
+	rq->cmd_len = 10;
 }
 
 The following seven ordered modes are supported.  The following table
