But calling EJ0 on any of the devices that might fit the bay will eject whatever is in the bay, regardless of it being the "active device" in the bay or not. This is why bay can be used in a thinkpad to eject BAT1 (a battery), their EJ0 handlers do exactly the same thing. You don't get the bay request eject and bay ejected events since bay.c doesn't tie itself to the battery ACPI node, but you can eject it. -- "One disk to rule them all, One disk to find them.
