Florian Westphal says:

====================
netfilter updates for net-next

First 4 Patches, from Yue Haibing, remove unused prototypes in
various netfilter headers.

Last patch makes nfnetlink_log to always include a packet timestamp,
up to now it was only included if the skb had assigned previously.
From Maciej Żenczykowski.
