* Differentiate between bay devices in dock stations and others: - When an ACPI_NOTIFY_EJECT_REQUEST appears, just signal uevent to userspace (that is when the optional eject button on a bay device is pressed/pulled) giving the possibility to unmount file systems and to clean up. Also, only send uevent in case we get an EJECT_REQUEST without doing anything else. In other cases, you'll get an add/remove event because libata attaches/detaches the device. - In case of a dock event, which in turn signals an ACPI_NOTIFY_EJECT_REQUEST, immediately detach the device, because it may already have been gone * In case of an ACPI_NOTIFY_DEVICE/BUS_CHECK, evaluate _STA to check if the device has been plugged or unplugged. If plugged, hotplug it, if unplugged, just signal event to userspace (initial patch by Matthew Garrett <mjg59@srcf.ucam.org>) * Call ACPI _EJ0 for detached devices Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
