Pablo Neira Ayuso says:

====================
This is the first batch of Netfilter and IPVS updates for your
net-next tree. Mostly cleanups for the Netfilter side. They are:

* Remove unnecessary RTNL locking now that we have support
  for namespace in nf_conntrack, from Patrick McHardy.

* Cleanup to eliminate unnecessary goto in the initialization
  path of several Netfilter tables, from Jean Sacren.

* Another cleanup from Wu Fengguang, this time to PTR_RET instead
  of if IS_ERR then return PTR_ERR.

* Use list_for_each_entry_continue_rcu in nf_iterate, from
  Michael Wang.

* Add pmtu_disc sysctl option to disable PMTU in their tunneling
  transmitter, from Julian Anastasov.

* Generalize application protocol registration in IPVS and modify
  IPVS FTP helper to use it, from Julian Anastasov.

* update Kconfig. The IPVS FTP helper depends on the Netfilter FTP
  helper for NAT support, from Julian Anastasov.

* Add logic to update PMTU for IPIP packets in IPVS, again
  from Julian Anastasov.

* A couple of sparse warning fixes for IPVS and Netfilter from
  Claudiu Ghioc and Patrick McHardy respectively.

Patrick's IPv6 NAT changes will follow after this batch, I need
to flush this batch first before refreshing my tree.
