  12          Open-Channel SSDs implement a set of extension to SSDs, that
  13          exposes direct access to the underlying non-volatile memory.

  26          Allows an open-channel SSD to be exposed as a block device to the
  27          host. The target assumes the device exposes raw flash and must be
  28          explicitly managed by the host.
