fs/xfs/linux/xfs_buf.c already has

  #ifdef RQ_WRITE_ORDERED
          if (flush)
                 set_bit(BH_Ordered_Flush, &bufferlist[cnt-1]->b_state);
  #endif

in _pagebuf_page_io.

Is this all I need (I already have applied the ide write barrier patch)
to safely use disk write back caching?

Thanks,
  Michael
