I notice in the acpi_bus_get_flags() function ejectable is defined as
anything that has either _EJ0 or _EJD.  However, the acpi pci hotplug
driver defines an ejectable slot as being one which must have (among
other things) _EJ0.  Is it legitimate to change the definition of an
ejectable slot to be one that has either _EJ0 or _EJD (in addition to
the other requirements for pci hotplug slots).

As the acpi_bus_get_flags() does, I think "ejectable device" is defined
as anything that has either _EJ0 or _EJD. But I don't think the device
is "ejectable slot" if it has _EJD but it doesn't have _EJ0. If an eject
request was notified to such devices, I don't know how to eject those.
I think one of the requirements for pci hotplug slots is having _EJ0.

Thanks,

I agree with Kenji's opinion.
I also worry about that if an eject request is raised on the
_EJD defined device.

Thank,
