Subject: [PATCH net-next 4/7] mptcp: remove redundant initialization in pm_nl_init_net()
Date: Thu, 27 May 2021 16:54:27 -0700 [thread overview]
Message-ID: <20210527235430.183465-5-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20210527235430.183465-1-mathew.j.martineau@linux.intel.com>
From: Jianguo Wu <wujianguo@chinatelecom.cn>
Memory of struct pm_nl_pernet{} is allocated by kzalloc()
in setup_net()->ops_init(), so it's no need to reset counters
and zero bitmap in pm_nl_init_net().
