I disagree - as I mentioned, not all laptops actually let you (userspace)
control the undock process because they don't lock. The dock driver
does notify user space of an undock, before it actually undocks:

/*
* here we need to generate the undock
* event prior to actually doing the undock
* so that the device struct still exists.
*/
dock_event(ds, event, UNDOCK_EVENT);
hotplug_dock_devices(ds, ACPI_NOTIFY_EJECT_REQUEST);
undock(ds);
eject_dock(ds);

We even notify other subsystems of our intent to undock prior to actually
doing it.
