Or to put it very bluntly: Could we make Arc<T> at least runtime enforce
(with the usual lockdep annotation trick like fs_reclaim) that and Drop is
the final one?

If that's the rust Arc<T> linux semantics then I think my worries are 100%
covered. And we'll sort out the trickier type based enforcement for
special cases when they hit us.

The downside is that this is substantially stricter than kref on the C
side, but I think that's a Good Thing :-)
