Add disk I/O stats for LVM/DM when
Submitted by Marius Gedminas
Please add disk I/O throughput statistics to libgtop. My primary reason for asking is to have a disk I/O graph in the multiload applet (see bug #157442).
On Linux systems, the data is available in /proc/stat (Linux 2.4) or /proc/diskstats (Linux 2.6).
