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
