Subject: [PATCH nfs-utils v3 04/14] mount: present AF_VSOCK addresses
Date: Wed, 13 Sep 2017 11:26:40 +0100
Message-Id: <20170913102650.10377-5-stefanha@redhat.com>
In-Reply-To: <20170913102650.10377-1-stefanha@redhat.com>
References: <20170913102650.10377-1-stefanha@redhat.com>
Sender: linux-nfs-owner@vger.kernel.org
List-ID: <linux-nfs.vger.kernel.org>

Format vsock hosts as "vsock:<cid>" so the addresses can be easily
distinguished from IPv4 and IPv6 addresses.
