Subject: [PATCH 07/27] netfilter: xt_connlimit: use rb_entry()
Date: Fri, 3 Feb 2017 13:25:18 +0100 [thread overview]
Message-ID: <1486124738-3013-8-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1486124738-3013-1-git-send-email-pablo@netfilter.org>
From: Geliang Tang <geliangtang@gmail.com>
To make the code clearer, use rb_entry() instead of container_of() to
deal with rbtree.
