sock: Introduce cred_to_ucred
To keep the coming code clear and to allow both the sock code and the scm code to share the logic introduce a fuction to translate from struct cred to struct ucred. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Acked-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
