Thanks for the reply Steinar.
The blktrace is a tool and I was wondering if there's something in / proc
itself that I can use
to get some info regarding the disk i/o per process.

Yes, there is.

echo 1 > /proc/sys/vm/block_dump

causes the kernel to log all I/O, so it all appears in your syslog. It's probably not something you want to leave switched on. :-)
