Reading the old thread, I think my main point was that we shouldn't output overcommit_ratio=0 when overcommit_bytes>0. We need to round up for numbers less than 1 so that folks don't think overcommit_ratio is _off_. I was really just trying to talk you in to cramming the extra precision in to the _existing_ sysctl. :) I don't think bytes vs. ratio is really that big of a deal. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
