* fix mount unmount failure for a Windows pod ([#63272](https://github.com/kubernetes/kubernetes/pull/63272), [@andyzhangx](https://github.com/andyzhangx))
* Fix concurrent map access panic ([#65327](https://github.com/kubernetes/kubernetes/pull/65327), [@dashpole](https://github.com/dashpole))
    * Don't watch .mount cgroups to reduce number of inotify watches

* Local volume source paths that are directories and not mount points fail to unmount.  A fix is in process ([#48331](https://github.com/kubernetes/kubernetes/issues/48331)).

 - [Action Required] CSI drivers that call IsLikelyNotMountPoint should not assume false means that the path is a mount point. Each CSI driver needs to make sure correct usage of return value of IsLikelyNotMountPoint because if the file is an irregular file but not a mount point is acceptable ([#129370](https://github.com/kubernetes/kubernetes/pull/129370), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage and Windows]
