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

32	Non-volatile memory media manager for Open-Channel SSDs that implements
33	physical media metadata management and block provisioning API.

35	This is the standard media manager for using Open-Channel SSDs, and
36	required for targets to be instantiated.

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