*I will send out a properly formatted patch shortly.*

So before you do that, can you explain in what cases fuse just wants
to pass through the IO?

Why aren't such cases just using unionfs or something?

In other words, I think that patch needs an explanation for the
*reason* for the new functionality.

Also, clarifying the functionality would be nice.  What is the
"underlying" fs you speak of?  What f_cred gets used?  Who opens the
underlying file, whatever that is?

Is the intent overlay-style stacking or is it something else entirely?
