From ce167a76d729dc858379d024dfc0fd85a26f32e1 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 31 Mar 2010 13:24:39 -0300 Subject: [PATCH 24/66] error: Replace qemu_error() by error_report() RH-Author: Markus Armbruster Message-id: <1270041921-28969-25-git-send-email-armbru@redhat.com> Patchwork-id: 8266 O-Subject: [PATCH 24/66] error: Replace qemu_error() by error_report() Bugzilla: 579470 RH-Acked-by: Kevin Wolf RH-Acked-by: Juan Quintela RH-Acked-by: Luiz Capitulino From: Markus Armbruster error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.
