Re: [v2 PATCH 0/2] rhashtable: rhashtable with duplicate objects

The stack trace is useless, but my other annotation showed that the
table's nelems *underflowed* to -1, so now the worker will continue
to try to grow it forever.

And this *was* actually a case of duplication, afaict, since it was
multiple virtual interfaces on the same device all connecting to the
same AP.
