From 6d0de8eb21b7a581999ca89a9b447fd1c91e23db Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 27 Aug 2014 12:08:54 +0100 Subject: mirror: fix uninitialized variable delay_ns warnings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The gcc 4.1.2 compiler warns that delay_ns may be uninitialized in mirror_iteration(). There are two break statements in the do ... while loop that skip over the delay_ns assignment. These are probably the cause of the warning.
