Rewrite the whole driver and drop the own code to calculate load average, disk and LAN load. Switch instead to use the in-kernel LED subsystem, which gives us quite some advantages, e.g. - existing triggers for heartbeat and disk/lan activity can be used - users can configre the LEDs at will to any existing trigger via /sys/class/leds - less overhead since we don't need to run own timers - fully integrated in Linux and as such cleaner code. Note that the driver now depends on CONFIG_LEDS_CLASS which has to be built-in and not as module. Signed-off-by: Helge Deller <deller@gmx.de>
