the function below causes compilation error in kernel configs with neither CONFIG_IPV6 nor
CONFIG_IPV6_MODULE defined.

should these functions be included between
#if defined(CONFIG_IPV6) || defined(CONFIG_IPV6_MODULE)

static inline struct ipv6_pinfo * inet6_sk(const struct sock *__sk)
{
return inet_sk(__sk)->pinet6;
}

static inline struct raw6_opt * raw6_sk(const struct sock *__sk)
{
return &((struct raw6_sock *)__sk)->raw6;
}
#endif


?? or should the #ifdef directive be removed from ipv6.h header file?

My fault, sorry... James Bottomley already pointed this out to me and I already
sent a fix to David Miller, CCed to netdev, here for convenience. It only
happens when you don't select IPV6.

I kindly suggest that such reports, related to networking development, at
least be CCed to netdev@xxxxxxxxxxxx
