Subject: [PATCH 1/8] can: fix memory leak in initial namespace support
Date: Tue, 25 Apr 2017 08:19:38 +0200 [thread overview]
Message-ID: <20170425061945.28722-2-socketcan@hartkopp.net> (raw)
In-Reply-To: <20170425061945.28722-1-socketcan@hartkopp.net>
The can_rx_alldev_list is a per-net data structure now and allocated in
can_pernet_init(). Make sure the memory is free'd in can_pernet_exit() too.
