This patchset enables sysfs eject for ACPI scan drivers and registers the ACPI container driver as an ACPI scan driver. This patchset is the one I mentioned in my following reply.

I think the container driver needs to be registered as an ACPI scan driver so that sysfs eject will continue to work for container devices, such as ACPI0004:XX/eject. Since the container driver does not support ACPI eject notification (and we have been discussing how system device hot-plug should work), this sysfs eject is the only way to eject a container device at this point. I will send an update patchset that applies on top of this patch. -- 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/
