Subject: [PATCH v4 net 2/4] dccp/tcp: Remove NULL check for prev_saddr in inet_bhash2_update_saddr().
Date: Sat, 19 Nov 2022 01:49:12 +0000	[thread overview]
Message-ID: <20221119014914.31792-3-kuniyu@amazon.com> (raw)

When we call inet_bhash2_update_saddr(), prev_saddr is always non-NULL.
Let's remove the unnecessary test.
