when CONFIG_IPV6=n.

Aleksey added IPv6 function to it but not change the Kconfig file.
The following patch will temporarily fix this build failure.
But IMHO separating the IPv4/IPv6 parts or using #ifdef would be better.

that's not good enough yet:

Aleksey will fix it by adding #if defined(CONFIG_IPV6) || defined(CONFIG_IPV6_MODULE) now.
See another thread "linux-next: origin tree build failure" :)
