  Kubernetes was previously detecting that the image filesystem was split, even when that was not really the case ([#128344](https://github.com/kubernetes/kubernetes/pull/128344), [@kannon92](https://github.com/kannon92)) [SIG Node]
- Fixed an issue in the kubelet that showed when writeable layers and read-only layers were at different paths within the same mount.

- Added `kubelet` stress test for pod cleanup when rejection due to `VolumeAttachmentLimitExceeded`. ([#133357](https://github.com/kubernetes/kubernetes/pull/133357), [@torredil](https://github.com/torredil)) [SIG Node and Storage]

- Removed a warning related to Linux user namespaces and kernel version. Previously, if the feature gate `UserNamespacesSupport` was enabled, the kubelet warned when detecting a Linux kernel version earlier than 6.3.0. While user namespace support generally requires kernel 6.3 or newer, it can also work on older kernels.
