Subject: [PATCH 1.1 3/4] xen_disk: remove syncwrite option
Date: Wed, 9 May 2012 13:44:15 +0100	[thread overview]
Message-ID: <1336567456-20202-3-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.00.1205091230380.26786@kaball-desktop>

This patch removes a dead option.

The same can be achieved removing BDRV_O_NOCACHE and BDRV_O_CACHE_WB
from the flags passed to bdrv_open.
