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, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
