- Scheduler's CycleState now embeds internal read/write locking inside its `Read()` and `Write()` functions. Meanwhile, `Lock()` and `Unlock()` function are removed. Scheduler plugin developers are now required to remove `CycleState#Lock()` and `CycleState#Unlock()`. Just simply use `Read()` and `Write()` as they're natively thread-safe now.

    * nonexistent.  This patch adds an anonymous function call inside
    * the loop to correctly handle acquiring the write lock with deferred
    * unlock to run at that function's completion, following the normal
    * golang lock/deferred-unlock pattern.
* Avoid creating new controller revisions for statefulsets when cache is stale ([#67039](https://github.com/kubernetes/kubernetes/pull/67039), [@mortent](https://github.com/mortent))

Additionally, these Kubernetes snapshot primitives act as basic building blocks that unlock the ability to develop advanced, enterprise-grade, storage administration features for Kubernetes: including application or cluster level backup solutions.
