Subject: [PATCH 3/4] net/smc: Print net namespace in log
Date: Tue, 28 Dec 2021 21:06:11 +0800 [thread overview]
Message-ID: <20211228130611.19124-4-tonylu@linux.alibaba.com> (raw)
In-Reply-To: <20211228130611.19124-1-tonylu@linux.alibaba.com>
This adds net namespace ID to the kernel log, net_cookie is unique in
the whole system. It is useful in container environment.
