Title:
  scsi disk emulation doesn't enforce FUA (Force Unit Access) in write-
  back mode

Status in QEMU:
  Won't Fix

Bug description:
  Microsoft NTFS utilizes the FUA bit in SCSI WRITE CDBs to insure
  integrity when a device advertises that it has write caching enabled.
  The FUA bit is meant to ensure a write is written to non-volatile
  storage before returning.  This seems to not be enforced by QEMU's
  SCSI emulation code.
