Look for the lm-profiler tool in the "laptop-mode" tools. It does
(almost) that :

That may or may not be what you want, however !

Thanks. That's a good start. Not what I was after but I'll see what it
gives me on my box. I'm looking for something like "Filemon" from
sysinternals.com (for Windows) - something that shows every operation
sent to the FS driver.
Thanks again.
