From 7edca33804f9b6948a65c04f969facf02a59e6fe Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Tue, 25 Oct 2016 15:11:31 +0200 Subject: [PATCH] block/nbd: Default port in nbd_refresh_filename() Instead of not emitting the port in nbd_refresh_filename(), just set it to the default if the user did not specify it. This makes the logic a bit simpler.
