- Fixed a bug where pv recycler failed to scrub volume with too many files in the directory due to hitting ARG_MAX limit with rm command (#117189). ([#117283](https://github.com/kubernetes/kubernetes/pull/117283), [@defo89](https://github.com/defo89)) [SIG Cloud Provider and Storage]...

* Fixed potential infinite loop that can occur when NFS PVs are recycled. ([#62572](https://github.com/kubernetes/kubernetes/pull/62572), [@joelsmith](https://github.com/joelsmith))

    *   AWS EBS volumes are detached if attached to a different node than expected. ([#55491](https://github.com/kubernetes/kubernetes/pull/55491),[ @gnufied](https://github.com/gnufied))
    *   PV Recycle now works in environments that use architectures other than x86. ([#53958](https://github.com/kubernetes/kubernetes/pull/53958),[ @dixudx](https://github.com/dixudx))

- Added warning for `PV` on reclaim policy when it is `Recycle`. ([#122339](https://github.com/kubernetes/kubernetes/pull/122339), [@carlory](https://github.com/carlory))

container, and uses `oom_scores` to recommend an order for killing container processes if an out-of-memory event occurs. This implementation has shortcomings: for `Guaranteed` pods, memory can not be fully reserved, and the page cache is at risk of being recycled. For `Burstable` pods, overcommitting memory (setting `request` less than `limit` ) could increase the risk of a container being killed when the Linux kernel detects an out of memory condition.

As an alpha feature, Kubernetes v1.22 can...
