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().

This series is based on Michael Tsirkin's vhost branch (v4.5-rc6). I'm about to process Claudio Imbrenda's locking fixes for virtio-vsock but first I want to share the latest version of the code. Several people are playing with vsock now so sharing the latest code should avoid duplicate work. v5: * Transport reset event for live migration support * Reorder virtqueues, drop unused
