atop and iotop are tools that do that...when the kernel has been appropriately patched or the kernel is of an appropriate version...
I did used these utilities, while it can help see what processes are generating IO, it doesn't show what files on the file system are being asked or waited for.
Basicly, what I'm searching is an equivalent for fs_usage on Mac OS X, or tcpdump, but on a bloc device...
Not sure what those do, but lsof should show what files are open, and 'strace -p process_id' would show the system calls issued by a process.
