``binder-control`` device cannot be deleted since this would make the binderfs
instance unuseable. The ``binder-control`` device will be deleted when the
binderfs instance is unmounted and all references to it have been dropped.
Binder features
---------------
Assuming an instance of binderfs has been mounted at ``/dev/binderfs``, the
features supported by the binder driver can be located under
``/dev/binderfs/features/``. The presence of individual files can be tested
to determine whether a particular feature is supported by the driver.
