mounter's Unmount implementation is changed to not return an error when the specified target can be detected as not a mount point. On Linux, the behavior of detecting a mount point depends on `umount` command is validated when the mounter is created. Additionally, mount point checks will be skipped in CleanupMountPoint/CleanupMountWithForce if the mounter's Unmount having the changed behavior of not returning error when target is not a mount point.

- Show a warning message to inform users that the debug container's capabilities granted by debugging profile may not work as expected if a non-root user is specified in target Pod's `.Spec.SecurityContext.RunAsUser` field.

- Limit number of instances in a single update to GCE target pool to 1000. ([#87881](https://github.com/kubernetes/kubernetes/pull/87881), [@wojtek-t](https://github.com/wojtek-t)) [SIG Cloud Provider, Network and Scalability]

- Volume attach or publish operation will not fail at `kubelet` if target path directory already exists on the node. ([#119735](https://github.com/kubernetes/kubernetes/pull/119735), [@akankshapanse](https://github.com/akankshapanse))

* A performance issue was identified in large-scale clusters when deleting thousands of pods simultaneously across hundreds of nodes. Kubelets in this scenario can encounter temporarily increased latency of `delete pod` API calls -- above the target service level objective of 1 second. If you run clusters with this usage pattern and if pod deletion latency could be an issue for you, you might want to wait until the issue is resolved before you upgrade.

*   Added a new --etcd-upgrade keyword to kubeadm upgrade apply. When this keyword is specified, etcd's static pod gets upgraded to the etcd version officially recommended for a target kubernetes release.

- Kubeadm: fixed a bug on 'kubeadm join' where using patches with a kubeletconfiguration target was not respected when performing the local kubelet healthz check. ([#126251](https://github.com/kubernetes/kubernetes/pull/126251), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

### Documentation

- The command`kubectl debug` will now print a warning message when using the `--target` option since many container runtimes do not support this yet. ([#101074](https://github.com/kubernetes/kubernetes/pull/101074), [@verb](https://github.com/verb))

### Failing Test

from the value obtained by executing and rounding the instructions individually.
An explicit <a href="#Numeric_types">floating-point type</a> <a href="#Conversions">conversion</a> rounds to
the precision of the target type, preventing fusion that would discard that rounding.

For instance, some architectures provide a "fused multiply and add" (FMA) instruction
