From 0d4127aea2e8580c3020729a6a8efe48e90d1b22 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek <lersek@redhat.com> Date: Wed, 8 May 2013 17:31:35 +0200 Subject: [PATCH] qga: distinguish binary modes in "guest_file_open_modes" map MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In Windows guests this may make a difference. Since the original patch (commit c689b4f1) sought to be pedantic and to consider theoretical corner cases of portability, we should fix it up where it failed to come through in that pursuit.
