Subject: [Qemu-devel] [PULL v2 6/9] libqos/ahci: Support expected errors
Date: Mon, 14 Nov 2016 11:25:43 -0500	[thread overview]
Message-ID: <1479140746-22142-7-git-send-email-jsnow@redhat.com> (raw)
In-Reply-To: <1479140746-22142-1-git-send-email-jsnow@redhat.com>

Sometimes we know we'll get back an error, so let's have the
test framework understand that.
