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

  32         Allows an open-channel SSD to be exposed as a block device to the
  33         host. The target is implemented using a linear mapping table and
  34         cost-based garbage collection. It is optimized for 4K IO sizes.
