Hi,
For the longest time, only the old PATA drivers supported barrier writes
with journalled file systems. This patch adds support for the same type
of cache flushing barriers that PATA uses for SCSI, to be utilized with
libata. It prepares to support barriers with 'real' SCSI hardware that
can

A few changes:
- Cleanup up the driver additions even more, blk_complete_barrier_rq()
does all the work now.
