From: Alastair D'Silva <redacted> Similar to the previous patch, this adds support for near storage commands. Signed-off-by: Alastair D'Silva <redacted> ---Is any of these new functions ever called?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.
It will be in the patch that implements overwrite. I moved that patch out of this series, as it needs more testing, so I guess I can submit this alongside it. -- Alastair D'Silva Open Source Developer Linux Technology Centre, IBM Australia mob: 0423 762 819
