Subject: [PATCH v2 net-next] net: sock: do not set sk_cookie in sk_clone_lock()
Date: Fri, 18 Jan 2019 13:00:51 +0800	[thread overview]
Message-ID: <1547787651-5119-1-git-send-email-laoar.shao@gmail.com> (raw)

The only call site of sk_clone_lock is in inet_csk_clone_lock,
and sk_cookie will be set there.
So we don't need to set sk_cookie in sk_clone_lock().
