0011 addition to storage devices this also enables libnvdimm to pass

0021 Some NVDIMM devices and controllers support encryption and
0022 other security features. The payloads for the commands that
0023 enable those features may contain sensitive clear-text
0024 security material. Disable debug of those command payloads
0025 by default. If you are a kernel developer actively working
0026 on NVDIMM security enabling say Y, otherwise say N.
