Is there a tool which will allow me to track io by process? I can do it 
by putting a printk in the kernel, rebuilding, and wading through MB of 
logs, but what I want is a way to find out which process or kthread is 
writing to my disk when the system is dead idle.

Of course the logging operation causes disk i/o... so it's kind of ugly 
to use.
