- Users can traverse all the pods that are in the scheduler and waiting in the permit stage through method `IterateOverWaitingPods`. In other words,  all waitingPods in scheduler can be obtained from any profiles. Before this commit, each profile could only obtain waitingPods within that profile.

### Failing Test

- Users can now traverse all the pods that are in the scheduler and waiting in the permit stage through method `IterateOverWaitingPods`. In other words,  all waitingPods in scheduler can be obtained from any profiles. Before this commit, each profile could only obtain `waitingPods` within that profile ([#122946](https://github.com/kubernetes/kubernetes/pull/122946), [@NoicFank](https://github.com/NoicFank))
