[PATCH v2 net-next 1/7] socket: Un-export __sock_create().

Kuniyuki Iwashima
2025-05-23T18:22:13Z

Since commit eeb1bd5c40ed ("net: Add a struct net parameter to
sock_create_kern"), we no longer need to export __sock_create()
and can replace all non-core users with sock_create_kern().

Let's convert them and un-export __sock_create().
