@dakrone, this is currently targeted only for 7.9 as it does not appear to be failing in master. Do you think it should go in master, too? Or other 7.x release branches? |

@danhermann I think 7.9 and master |

We're seeing test failures in 7.x on debian8 (though I have not been able to reproduce them) with negative values for used memory which we compute as
total - free. We already coerce both total and free memory to zero if negative values are reported for either because @dakrone's work in #42725 demonstrated that negative values can be returned. That said, it does not appear that those occurrences necessarily coincide such that total may be reported as negative but free is reported as positive thus resulting in a potentialfree > totalsituation.Backport of #56435
