  # According to the kernel docs[1], the major block numbers from 240 to 254 are allocated
  # dynamically by the kernel for devices which don't have official numbers assigned. It looks like
  # that "dm" (device mapper) and "zram" are such devices. To avoid issues when kernel config
  # changes, it's better to allow the whole range (240-254) instead of the single major numbers
  # visible in the /proc/devices file.
