Review request for kde-workspace and John Tapsell.

Repository: kde-workspace


IO-wait is included in the cpu usage. This is wrong since IO-wait is a part of the idle time. This goes for both total combines CPU-usage and the per CPU usage.


  ksysguard/ksysguardd/Linux/stat.c 534a465 



Fx. running a read from a slow USB-media like this will always end up showing 25% load on my system (I have 4 cores)

dd if=/dev/sdb of=/dev/null bs=1M 

This end up being around 0% with my patch.
