What are the top ten most interesting vfs calls for statistics purposes? 2. How important is it to *not* change the statfs structure? (I know this breaks a lot of tools, I've tried it already) 3. Is it ok for me to use the f_spare[10] slot in statfs for this? 4. If 4 is OK, then is 10 enough for storing the most important calls? If it isn't, then I'm stuck breaking the statfs struct, right? Thanks!
