patch to flush data to disk
Description of problem:
The SCSI backend does not make sure data is actually written to disk before scsi_write_data() returns. Calling bdrv_flush will fix this, in the exact same way we fixed it in the IDE emulation around RHEL 5 GA time.
This patch is not needed for upstream, because the bdrv_aio_* framework takes care of IO completion issues automatically.
Fix built into xen-3.0.3-82.el5
