C++ (Cpp) blk_mq_end_io Examples

Example #1

File: virtio_blk.c Project: 24hours/linux

static inline void virtblk_request_done(struct request *req)
{
	struct virtblk_req *vbr = blk_mq_rq_to_pdu(req);
	int error = virtblk_result(vbr);

		req->errors = vbr->in_hdr.errors;
	} else if (req->cmd_type == REQ_TYPE_SPECIAL) {
		req->errors = (error != 0);
	}

	blk_mq_end_io(req, error);
}

Example #2

	if (queue_mode != NULL_Q_MQ)
		free_cmd(cmd);
}
