Subject: [PATCH net-next 9/9] net: tcp: use LINUX_MIB_TCPABORTONLINGER in tcp_rcv_state_process()
Date: Sat, 29 Oct 2022 21:09:57 +0800 [thread overview]
Message-ID: <20221029130957.1292060-10-imagedong@tencent.com> (raw)
In-Reply-To: <20221029130957.1292060-1-imagedong@tencent.com>
From: Menglong Dong <imagedong@tencent.com>
The statistics for 'tp->linger2 < 0' in tcp_rcv_state_process() seems
more accurate to be LINUX_MIB_TCPABORTONLINGER.
