Yes, and also that sleeping in the sysfs read function is not desirable. Personally, I was fine with that, but Mr. de Goede was concerned about it, so I decided to try to fix it. I admit, the dual-delayed-workqueue method is a bit strange, but it solves the reading problem at a slight cost of waking up the CPU even if nobody's watching the sensors. > Hmm...

I was trying to use as little resources as possible, and a kernel thread seemed like overkill for a hwmon device. --D -------------- next part -------------- A non-text attachment was scrubbed...
