    Ok, so now yet another suggestion, which may sound a little strange:

    oprofilefs

    I believe you can use the oprofile infrastructure to record data
    about file accesses, even independent of the file system you
    are looking at.

    It's probably a lot of work to get it right, but I would be worth it.
