The underlying reason is that stat()'ing a file on btrfs delivers a
bogus "0:17" device instead of the actual underlying device, presumably
because btrfs is actually an abstraction layer for multiple physical
devices, much like LVM. So it would require btrfs specific calls to
determine whether any of the underlying physical devices is on a
rotational drive.
