[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.
