Hi, I think that it is exactly what holders/slaves do - displaying device hierarchy. So application can check which underlying device are related and ask them for more info if needed (=> with system specific call, it can be simple sysfs attribute, ioctl, whatever). So the only request here is to keep these symlinks correct, nothing more. Or am I missing anything? Milan -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
