I'm still not sure what kind of special support you need. The only
guarantee you need to provide is that after a barrier all reads on all
nodes return the same data for those blocks affected by the flush.

The shared disk file system itself will take care of issueing
appropriate barrier and flushing the OS caches.

Am I missing something? ;-)
