	// If a volume has 'Filesystem' volumeMode, MountVolume mounts the
	// volume to the pod specified in volumeToMount.
	// Specifically it will:
	// * Wait for the device to finish attaching (for attachable volumes only).
	// * Mount device to global mount path (for attachable volumes only).
	// * Update actual state of world to reflect volume is globally mounted (for
	//   attachable volumes only).
	// * Mount the volume to the pod specific path.

  // RecursiveReadOnly specifies whether read-only mounts should be handled
  // recursively.
  //
  // If ReadOnly is false, this field has no meaning and must be unspecified.
  //
  // If ReadOnly is true, and this field is set to Disabled, the mount is not made
  // recursively read-only.  If this field is set to IfPossible, the mount is made

- Fixed an issue where mount points could become local without calling `NodePublishVolume` after node rebooting.
   ([#119923](https://github.com/kubernetes/kubernetes/pull/119923), [@cvvz](https://github.com/cvvz))
- Fixed cleanup of Pod volume mounts when a file was used as a subpath.
