Subject: [PATCH v2 net-next 5/9] mptcp: snmp: do not use SNMP_MIB_SENTINEL anymore
Date: Fri, 5 Sep 2025 16:58:09 +0000 [thread overview]
Message-ID: <20250905165813.1470708-6-edumazet@google.com> (raw)
In-Reply-To: <20250905165813.1470708-1-edumazet@google.com>
Use ARRAY_SIZE(), so that we know the limit at compile time.
