Review request for mesos, Benjamin Mahler and Michael Park. Bugs: MESOS-8604 https://issues.apache.org/jira/browse/MESOS-8604 Repository: mesos Description ------- When calculating the quota headroom, we failed to consider ancestor's reservation allocated to the child. This leads to under-estimation of available headroom and excessive resources being set aside for headroom. See MESOS-8604. This patches fixes this issue by counting ancestor's reservation allocated to the child as allocated-reservation even though the child itself has no reservation.
