I'm still not sold on this idea at all. I'm really betting that there is a lot of incorrect acpi slot information floating around in machines and odd things will show up in these slot entries. I say this because for a long time there was no "standard" acpi entries for hotplug slots and different companies did different things. Hence the "odd" IBM acpi hotplug implementation as one example. If this is going to go anywhere, you need to get IBM to agree that it works properly with all their machines... Also, some companies already provide userspace tools to get all of this information about the different slots in a system and what is where, from userspace, no kernel changes are needed. So, why add all this extra complexity to the kernel if it is not needed? thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
