[dm-devel] In discovery.c, Sysfs attribute is not closed while collecting target node name...



Hi,

Here is the code snippet from scsi_sysfs_pathinfo function.
attr is not closed when target node name is collected successfully. The
function just returns 0 at the end. 
Shouldn't it be sysfs_close_attribute(attr); and then return 0; ???

	/*
	 * target node name
	 */
	if(safe_sprintf(attr_path,
	
"%s/class/fc_transport/target%i:%i:%i/node_name",
			sysfs_path,
			pp->sg_id.host_no,
			pp->sg_id.channel,
			pp->sg_id.scsi_id)) {
		condlog(0, "attr_path too small");
		return 1;
	}
	if (!(attr = sysfs_open_attribute(attr_path)))
		return 0;

	if (sysfs_read_attribute(attr))
		goto err;

	if (attr->len > 0)
		strncpy(pp->tgt_node_name, attr->value, attr->len - 1);

	condlog(3, "%s: tgt_node_name = %s",
		pp->dev, pp->tgt_node_name);

	return 0;
err:
	sysfs_close_attribute(attr);
	return 1;

Best Regards,
Rajashekhar M A
