Subject: [PATCH v2 net-next 1/5] net_sched: constify qdisc_priv()
Date: Wed, 20 Sep 2023 20:17:11 +0000 [thread overview]
Message-ID: <20230920201715.418491-2-edumazet@google.com> (raw)
In-Reply-To: <20230920201715.418491-1-edumazet@google.com>
In order to propagate const qualifiers, we change qdisc_priv()
to accept a possibly const argument.
