No objection. I have a patch prepared which allows the user to
provide ht->mutex himself so nfset can provide its own existing
mutex to rhashtable and lock out the resizes from inserts,
removals and dump iterations automatically That would restore the
old behaviour of the nfset API without major surgery.
I was just waiting on your walker as you requested a hold off.
