This is my concern as well. The libnvdimm command support is limited
to the commands that Linux will use. Other passthrough commands are
supported through a passthrough interface. However, that passthrough
interface is explicitly limited to publicly documented command sets so
that the kernel has an opportunity to constrain and consolidate
command implementations across vendors.
