  	help
  	  Say Y here to get to enable Open-channel SSDs.
  
  	  Open-Channel SSDs implement a set of extension to SSDs, that
  	  exposes direct access to the underlying non-volatile memory.

  config NVM_GENNVM
  	tristate "Generic NVM manager for Open-Channel SSDs"
  	---help---
  	NVM media manager for Open-Channel SSDs that offload management
  	functionality to device, while keeping data placement and garbage
  	collection decisions on the host.
  
  config NVM_RRPC
  	tristate "Round-robin Hybrid Open-Channel SSD target"
  	---help---
  	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.
