Thanks Berny pointing me in this direction.

Clarification: This feature is not about the source device but the "device
number" reported by the filesystem in `stat()`. For xfs and probably many
other filesystems, this happens to be (major<<8)+minor of the source device
but btrfs, for example, allocates a new number for each subvolume.
