Subject: [Qemu-devel] [PATCH] virtio-blk: Respect werror option for flushes
Date: Wed, 20 Oct 2010 17:23:52 +0200	[thread overview]
Message-ID: <1287588232-8482-1-git-send-email-kwolf@redhat.com> (raw)

The werror option now affects not only write requests, but also flush requests.
Previously, it was not possible to stop a VM on a failed flush.
