now there are plenty of compiler-warnings when CONFIG_CGROUPS is not set:

In file included from include/linux/tcp.h:211:0,
                 from include/linux/ipv6.h:221,
                 from include/net/ip_vs.h:23,
                 from kernel/sysctl_binary.c:6:
include/net/sock.h:67:57: warning: ‘struct cgroup_subsys’ declared
inside parameter list [enabled by default]
include/net/sock.h:67:57: warning: its scope is only this definition or
declaration, which is probably not what you want [enabled by default]
include/net/sock.h:67:57: warning: ‘struct cgroup’ declared inside
parameter list [enabled by default]
include/net/sock.h:68:61: warning: ‘struct cgroup_subsys’ declared
inside parameter list [enabled by default]
include/net/sock.h:68:61: warning: ‘struct cgroup’ declared inside

Because struct cgroup is only declared if CONFIG_CGROUPS is enabled.
(cfr. linux/cgroup.h)
