Subject: [PATCH 01/42] net/can: single_open_net needs to be paired with single_release_net
Date:   Wed, 16 May 2018 11:43:05 +0200
Message-Id: <20180516094346.20506-2-hch@lst.de>
In-Reply-To: <20180516094346.20506-1-hch@lst.de>
References: <20180516094346.20506-1-hch@lst.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Otherwise we will leak a reference to the network namespace.
