Well, the minute you see a 'struct DeviceFactory' appear in the kernel source you can delete all the unit tests and come take away my keyboard. Until then can we please push probing platform resources to a device driver ->probe() method where it belongs? Also given the type-7 type-12 confusion I'm just waiting for some firmware to describe persistent memory with type-12 at the e820 level and expect an ACPI-NFIT to be able to sub-divide it. In that case you'd want to blacklist either 'nd_e820.ko' or 'nfit.ko' to resolve the conflict. I'm not grokking the argument against allowing this functionality to be modular. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
