In fact, we can make it even simpler than dynamically changing family, just have ND_IOCTL_VENDOR always route to uuid ""4309ac30-0d11-11e4-9191-0800200c9a66" and function number 9. Then that becomes the de facto method for Linux to issue a vendor-specific command for any DIMM. _______________________________________________ Linux-nvdimm mailing list [email protected] https://lists.01.org/mailman/listinfo/linux-nvdimm
