Mmm... Where (hypervisor, dom0/domu kernel space, user space) and for
what reason you need that?

I'm asking because, at some point, I needed a _similar_ information, and
wrote this:


It's probably not exactly what you mean, but it has the capability of
showing who is using some MFNs.

The point is I only needed it for debugging/understanding purposes so,
if your aim is different, it may not fit.
