  - Added validation to enforce the hugepage aggregated container limits to be smaller than or equal to pod-level limits. This was already enforced with the defaulted requests from the specified limits, however it did not make it clear about both hugepage requests and limits.

* New alpha feature limits the number of processes running in a pod. Cluster administrators will be able to place limits by using the new kubelet command line parameter --pod-max-pids.

By default, we do not set any maximum limit, If an administrator wants to enable this, they should enable SupportPodPidsLimit=true in the --feature-gates=...
