C++ (Cpp) blk_complete_request Examples

Example #1

File: null_blk.c Project: 0x000000FF/edison-linux

static inline void null_handle_cmd(struct nullb_cmd *cmd)
{
	/* Complete IO by inline, softirq or timer */

		switch (queue_mode)  {
		case NULL_Q_MQ:
			blk_mq_complete_request(cmd->rq);
			break;
		case NULL_Q_RQ:
			blk_complete_request(cmd->rq);
			break;
		case NULL_Q_BIO:
			/*
			 * XXX: no proper submitting cpu information available.
			 */
			end_cmd(cmd);
			break;
		}
		break;
	case NULL_IRQ_NONE:
		end_cmd(cmd);
		break;
	case NULL_IRQ_TIMER:
		null_cmd_end_timer(cmd);
		break;
	}
}

Example #2

File: dm-rq.c Project: ReneNyffenegger/linux

/*
 * Complete the clone and the original request with the error status
 * through softirq context.
 */
static void dm_complete_request(struct request *rq, blk_status_t error)

	tio->error = error;
	if (!rq->q->mq_ops)
		blk_complete_request(rq);
	else
		blk_mq_complete_request(rq);
}

Example #3

		  unsigned int reply_payload_rcv_len)
