The kernel option means we can autodetect the nvdimms in kernel space with just that option set, no need for needing userspace setup. How does your script / patch work? I won't be back to my nvdimm enabled hardware until after LSF/MM, so any work from me in this area will have to wait a bit. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
