@calebamiles -- i had updated the description text last week but forgot to update the label for 1.8, updated now as this is being done via sig-node.

Automatic merge from submit-queue HugePages proposal A pod may request a number of huge pages. The `scheduler` is able to place the pod on a node that can satisfy that request. The `kubelet` advertises an allocatable number of huge pages to support scheduling decisions. A pod may consume hugepages via `hugetlbfs` or `shmget`. Planned as Alpha for Kubernetes 1.8 release. See feature: kubernetes/enhancements#275 @kubernetes/sig-scheduling-feature-requests @kubernetes/sig-scheduling-misc @kubernetes/sig-node-proposals @kubernetes/api-approvers @kubernetes/api-reviewers
