Subject: [Qemu-devel] [PATCH v2 19/21] qemu-iotests: Try setting cache mode for children
Date: Mon, 23 Nov 2015 16:59:58 +0100	[thread overview]
Message-ID: <1448294400-476-20-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1448294400-476-1-git-send-email-kwolf@redhat.com>

This is a basic test for specifying cache modes for child nodes on the
command line. It doesn't take much time and works without O_DIRECT
support.
