We have enough cases where "exit" is used that way starting with
module_exit() and all the accompanying __exit annotations and there
are quite a few others.  I think it's enough to establish "exit" as
the counterpart of "init" but I do agree that it felt a bit alien to
me at the beginning too.

In general, I've been sticking with create/destroy if the object
itself is being created or destroyed and init/exit if the object
itself stays put across init/exit which is the case here.  This isn't
quite universal but I think there exists enough of a pattern to make
it worthwhile to stick to it.  As such, I'd like to stick to the
current names if it isn't a big deal.

Thanks.
