Greg Kroah-Hartman b258964700 lightnvm: disable the subsystem
In commit 9ea9b9c48387 ("remove the lightnvm subsystem") the lightnvm
subsystem was removed as there is no hardware in the wild for it, and
the code is known to have problems.  This should also be disabled for
older LTS kernels as well to prevent anyone from accidentally using it.

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

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.

help
Enables debug support for pblk. This includes extra checks, more
vocal error messages, and extra tracking fields in the pblk sysfs
entries.
