   9          Say Y here to get to enable Open-channel SSDs.
  10
  11          Open-Channel SSDs implement a set of extension to SSDs, that
  12          exposes direct access to the underlying non-volatile memory.

  14          If you say N, all options in this submenu will be skipped and disabled
  15          only do this if you know what you are doing.

  25          /sys/module/lnvm/parameters/configure_debug

  27        It is required to create/remove targets without IOCTLs.

  31        ---help---
  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.

  36config NVM_PBLK
  37        tristate "Physical Block Device Open-Channel SSD target"
  38        ---help---
  39        Allows an open-channel SSD to be exposed as a block device to the
  40        host. The target assumes the device exposes raw flash and must be
  41        explicitly managed by the host.

  43        Please note the disk format is considered EXPERIMENTAL for now.
