Thomas, it appears that rhashtable as it stands cannot handle
changing the random seed because of the way it constructs the
new hash table without degrading into a linked list.  Is there
something I'm missing?

FWIW my hashtable in net/bridge/br_multicast.c handles rehashing
correctly.  Any objections to me converting rhashtable to use my
scheme instead?

Cheers,
