Bug fix: handles disk device used multiple times There were issues in having the same underlying device being referenced multiple times (via different paths) when reporting storage I/O statistics. As an example: having two (or more) LVM2/DM volumes crafted out of the same MD array. This patch simply skips over any devices previously seen. Signed-off-by: Alan D.
