Also, DIX is only the tip of the iceberg. Many other impending

The VM is already trying to do the right thing. We just need the
relevant filesystems to catch up.

	ocfs2 handles stable metadata for its checksums when feeding
things to the journal.  If we're doing pagecache-based I/O, is the
pagecache going to help here for data?
