For the first iteration of Open-Channel SSDs, it was anticipated that there could be various media managers on top of an open-channel SSD, such to allow vendors to plug in their own host-side FTLs, without the media manager in between. Now that an Open-Channel SSD is exposed as a traditional block device, there is no longer a need for this. Therefore lets merge the gennvm code with core and simplify the stack.

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

Allows an open-channel SSD to be exposed as a block device to the

host. The target is implemented using a linear mapping table and
|
|
cost-based garbage collection. It is optimized for 4K IO sizes.
