> Alvaro could you pls explain the use-case? Christoph has doubts that > it's useful. Do you have a device implementing this? Our HW exposes virtio devices, virtio block included. The block device backend can be a eMMC/uSD card. The HW can report health values (power, temp, current, voltage) and I thought that it would be nice to be able to report lifetime values as well. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/dm-devel
