Subject: [PATCH net 0/2] rhashtable updates

As discussed, I'm sending out rhashtable fixups for -net.

I have a couple of more patches I was working on last week pending,
i.e. to get rid of ht->nelems and ht->shift atomic operations which
speed-up pure insertions/deletions, e.g. on my laptop I have 2 threads,
inserting 7M entries each, that will reduce insertion time from ~1,450 ms
to 865 ms (performance should even be better after removing the
grow/shrink indirections). I guess that however is rather something
for net-next.

Thanks,
Daniel

  rhashtable: unconditionally grow when max_shift is not specified
  rhashtable: remove indirection for grow/shrink decision functions
