([#121720](https://github.com/kubernetes/kubernetes/pull/121720), [@aojea](https://github.com/aojea))
- A deprecated flag `--pod-max-in-unschedulable-pods-duration` was initially planned to be removed in v1.26, but we had to change this plan. We found [an issue](https://github.com/kubernetes/kubernetes/issues/110175) in which Pods can be stuck in the unschedulable pod pool for 5 min, and using this flag is the only workaround for this issue.
