| 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. |

| If you say N, all options in this submenu will be skipped and disabled |

| Exposes a debug management interface to create/remove targets at: |
| |
| /sys/module/lnvm/parameters/configure_debug |

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

| tristate "Physical Block Device Open-Channel SSD target" |
| ---help--- |
| Allows an open-channel SSD to be exposed as a block device to the |
| host. The target assumes the device exposes raw flash and must be |
| explicitly managed by the host. |
| |
| Please note the disk format is considered EXPERIMENTAL for now. |
