From 222934faee20b22e77f711d6bc5d986c2e1fd297 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Mon, 2 Jul 2018 12:20:17 +0200 Subject: [PATCH 51/57] usb-storage: Add rerror/werror properties RH-Author: Kevin Wolf Message-id: <20180702122017.29664-2-kwolf@redhat.com> Patchwork-id: 81183 O-Subject: [RHV-7.6 qemu-kvm-rhev PATCH 1/1] usb-storage: Add rerror/werror properties Bugzilla: 1595180 RH-Acked-by: Paolo Bonzini RH-Acked-by: Max Reitz RH-Acked-by: John Snow The error handling policy was traditionally set with -drive, but with -blockdev it is no longer possible to set frontend options. scsi-disk (and other block devices) have long supported qdev properties to configure the error handling policy, so let's add these options to usb-storage as well and just forward them to the internal scsi-disk instance.
