Now I agree that it would be nice to support barriers in GFS2, but it
won't solve any problems relating to ordering of I/O unless all of the
underlying device supports them too. See also Alasdair's response to the

So although I'd like to see barrier support in GFS2, it won't solve any
problems for most people and really its a device/block layer issue at
the moment.
