Subject: xen_disk: remove syncwrite option
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=ba1dffed6342f900595b97435c05646f559b5ea7;p=qmiga%2Fqemu.git

xen_disk: remove syncwrite option

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.
