Careful, "direct I/O" is a term already used in fuse for a different
thing.  Let's call it "direct access" instead.

I'm not aware of such an implementation.  But for comparing the speed
of direct access vs. access throgh fuse, you don't actually need an
implementation.  Just run the benchmark on the lower FS directly, that
will be a good approximation of what may be achieved with direct
access.
