Subject: [PATCH net-next 1/2] mptcp: don't need to check SKB_EXT_MPTCP in mptcp_reset_option()
Date: Fri,  5 Apr 2024 10:39:13 +0800	[thread overview]
Message-ID: <20240405023914.54872-2-kerneljasonxing@gmail.com> (raw)
In-Reply-To: <20240405023914.54872-1-kerneljasonxing@gmail.com>

From: Jason Xing <kernelxing@tencent.com>

Before this, what mptcp_reset_option() checks is totally the same as
mptcp_get_ext() does, so we could skip it.
