I misread it here when i looked at this mail for the first time. :) I strongly believe that we need a full stop (.) before "Every sampling_rate", otherwise it looks like we check for down_factor while increasing freq :) > * > > Also checking the code before the commit > 8e677ce83bf41ba9c74e5b6d9ee60b07d4e5ed93 you may see that sampling down > factor works in this way. > So, I decided to keep the original functionality (also down_skip was already > there unused). I got that comment but i belive the code was never according to that comment and not even now. Check the initial patch for conservative governor: b9170836d1aa4ded7cc1ac1cb8fbc7867061c98c Even now we aren't checking this 80% thing, right? And so in your patch we can actually fix the patch too with the right logic of code.. And documentation too :) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
