As pointed out by Toshi Kani, the above changes would make acpi_eject_store()
fail for containers and it is the only way to eject them currently, so patch
[2/2] is an improved version of this (with Toshi's changes folded in).

Patch [1/2] is just a cleanup removing a useless #ifndef from acpi_eject_store().


I speak only for myself.
