What are you trying to learn from the kernel?  I think it'd be handy
to have a monitor that would alert if a process started doing more
than a certain amount of block i/o operations.  Or perhaps a monitor
that alerted on disk i/o bandwidth utilization (iostat -x %util) could
use SystemTap to show you which processes would be likely culprits.
