  are no technical obstacles preventing that, so it got enabled with a warning
  about potential dangers when the device will not do the duplicated copies. See
  mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.

  Note: due to backward compatibility, the range maximum for 'usage' is not
  inclusive as for the others, to keep the same behaviour as usage=N .
