Commit e1aab161e013 ("socket: initial cgroup code.") causes a build error
when CONFIG_INET is disabled in Linus' tree:
net/built-in.o: In function `sk_update_clone':
net/core/sock.c:1336: undefined reference to `sock_update_memcg'
sock_update_memcg() is only defined when CONFIG_INET is enabled, so fix it
by defining the dummy function without this option.

Checking the logs, Randy reported this in an email to LKML on
September 24 and didn't get a response...
