> AFAIU, "relaxed" means the statistics could become entirely wrong, e.g. they could diverge more and more from the actual values. "acq-rel" ensures they converge to the actual values if no allocation happens for a long enough period of time. I think `compare_exchange` would gurantee the "update" maximum would be right (rather than diverge more and more from the actual values). Other operations just mean a little ( not more and more) from the actual values? -- This is an automated message from the Apache Git Service.
