lsblk is awesome for viewing a system's storage stack. However, it
would be great if it just spit out the list of devices sharing a
multipath name instead of repeating the full tree for each device.
lsblk -i from version 2.29.2, only one tree shown but the exact same
tree appears under sdai as well on my example host.
