I agree with Mike's point here, relax the restriction usually benefit one model but damage more. The whole wake_affine() stuff is somewhat blindly, we image that the cache will benefit the wakee but could not estimate how much it is, and the formula contain too many elements, I'd prefer to gamble only when I'm likely to win, that will win less money, but lose less too ;-) Regards, Michael Wang > > Thanks, > Namhyung > > > -- > 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/ > -- 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/
