Subject: [RFC PATCH 1/3] net: Remove unnecessary memset in __snmp6_fill_stats64
Date: Mon, 8 Aug 2016 18:22:20 +0800 [thread overview]
Message-ID: <1470651742-15195-2-git-send-email-hejianet@gmail.com> (raw)
In-Reply-To: <1470651742-15195-1-git-send-email-hejianet@gmail.com>
buff[] will be assigned later, so memset is not necessary.
