[PATCH] s390: enable write barriers in the dasd driver
The DASD device driver never reorders the I/O requests and relies on the
hardware to write all data to nonvolatile storage before signaling a
successful write. Hence, the only thing we have to do to support write
barriers is to set the queue ordered flag.
