Subject: [PATCH net-next 10/14] hv_sock: set VMADDR_CID_HOST in the hvs_remote_addr_init()
Date: Wed, 23 Oct 2019 11:55:50 +0200
Message-ID: <20191023095554.11340-11-sgarzare@redhat.com> (raw)
In-Reply-To: <20191023095554.11340-1-sgarzare@redhat.com>

Remote peer is always the host, so we set VMADDR_CID_HOST as
remote CID instead of VMADDR_CID_ANY.
