I've just realised that the message in domU is from the blkfront driver,
so you wouldn't expect to see it in dom0. Also since it is not from the
filesystem it will not necessarily coincide with the filesystems use of
barriers, it'll just reflect that the device *could* do barriers.

To know if the filesystem is using barriers I think you have to look
in /proc/mounts.
