Subject: [PATCH net-next 1/8] net: use DEBUG_NET_WARN_ON_ONCE() in __release_sock()
Date: Tue, 7 Jun 2022 10:17:25 -0700 [thread overview]
Message-ID: <20220607171732.21191-2-eric.dumazet@gmail.com> (raw)
In-Reply-To: <20220607171732.21191-1-eric.dumazet@gmail.com>
From: Eric Dumazet <edumazet@google.com>
Check against skb dst in socket backlog has never triggered
in past years.
Keep the check only for CONFIG_DEBUG_NET=y builds.
