    Hi Manik

    and sorry that I read only half of your initial post.
    I had a quick look at fs/read_write.c.

    I don't see any hook in the functions here, to perform such a task. And
    here this should belong to -- shouldn't it?

    the functions could add ``count'' to the procfs entry of ``current''.
    (just a thought) This info could be valuable - I think - if it wouldn't
    make a large performance issue.

    Regards
    Frank
