Subject: [Patch net 13/15] net_sched: add rtnl assertion to tcf_exts_destroy()
Date: Mon, 23 Oct 2017 15:03:02 -0700 [thread overview]
Message-ID: <20171023220304.2268-14-xiyou.wangcong@gmail.com> (raw)
In-Reply-To: <20171023220304.2268-1-xiyou.wangcong@gmail.com>
After previous patches, it is now safe to claim that
tcf_exts_destroy() is always called with RTNL lock.
