Subject: [RFC PATCH 08/13] vsock: move vsock_insert_unbound() in the vsock_create()
Date: Fri, 27 Sep 2019 13:26:58 +0200
Message-ID: <20190927112703.17745-9-sgarzare@redhat.com> (raw)
In-Reply-To: <20190927112703.17745-1-sgarzare@redhat.com>

vsock_insert_unbound() was called only when 'sock' parameter of
__vsock_create() was not null. This only happened when
__vsock_create() was called by vsock_create().

In order to simplify the multi-transports support, this patch
moves vsock_insert_unbound() at the end of vsock_create().
