Tracking flash IO activity?

[valent.turkovic at gmail.com]

I have used iostat but it is not showing any changes on /dev/mtdblock5
which is mounted as /overlay jffs2 partition on this device I'm using.
I have also checked stats in /proc/diskstat, and they also only change
for /dev/mmcblk0p1 which is usb device, but not for any of
/dev/mtdblockX partitions.
