There was a discussion about that on Kernel Summit 2003 and general opinion was that
SCSI
does not need the WB stuff at all as it does the correct thing anyway.
But since the the barrier flags are visible in io requests, actual device drivers
are free to do something when met with barrier requests or to ignore it.
The only concern is probably raid cards that show bunch of IDE drives as a SCSI device.
