Subject: [PATCH 5/5] netfilter: fix error return value of nf_ct_l4proto_pernet_register_one()
Date: Wed, 5 Dec 2018 20:56:30 +0800 [thread overview]
Message-ID: <1544014590-14429-5-git-send-email-laoar.shao@gmail.com> (raw)
In-Reply-To: <1544014590-14429-1-git-send-email-laoar.shao@gmail.com>
If pn is NULL, it will return 0.
That's not proper. We should return an error.
