Without CRC32 support, this fails to link:
arm-linux-gnueabi-ld: drivers/lightnvm/pblk-init.o: in function `pblk_init':
pblk-init.c:(.text+0x2654): undefined reference to `crc32_le'
arm-linux-gnueabi-ld: drivers/lightnvm/pblk-init.o: in function `pblk_exit':
pblk-init.c:(.text+0x2a7c): undefined reference to `crc32_le'
Fixes: a4bd217b43 ("lightnvm: physical block device (pblk) target")

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

only do this if you know what you are doing.

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.

Enables debug support for pblk. This includes extra checks, more
