Volume that failed Detach() should not be marked as attached, CSI
external-attacher is probably still trying to detach it.
Mark it uncertain instead and wait for Detach() to succeed.
The subpath could be passed a powershell subexpression which would be executed by kubelet with privilege. Switching to pass the arguments via environment variables means the subexpression won't be evaluated.

PVC and containers shared the same ResourceRequirements struct to define their
API. When resource claims were added, that struct got extended, which
accidentally also changed the PVC API. To avoid such a mistake from happening
again, PVC now uses its own VolumeResourceRequirements struct.
The `Claims` field gets removed because risk of breaking someone is low:
theoretically, YAML files which have a claims field for volumes now
get rejected when validating against the OpenAPI. Such files
have never made sense and should be fixed.
Code that uses the struct definitions needs to be updated.
This replaces deprecated ioutil variables and functions as follows:
* ioutil.ReadDir -> os.ReadDir
* ioutil.ReadFile -> os.ReadFile
* ioutil.TempDir -> os.MkdirTemp
* ioutil.TempFile -> os.CreateTemp
* ioutil.WriteFile -> os.WriteFile
The ReadDir conversion involves an API change, the replacement
function returns a slice of fs.DirEntry instead of fs.FileInfo.
Where appropriate, the surrounding code has been adjusted; mostly,
that means using DirEntry.Type() instead of FileInfo.Mode().
Applying this change to the IoUtil interface would mean changing its
API, so this is left for later.

GetFileType is meant to return the type of the given file by using os.Stat.
However, os.Stat doesn't work on Windows for Unix Sockets, causing an error to occur:
[2-Socket Test] unexpected error :
CreateFile C:\Users\Administrator\AppData\Local\Temp\test-get-filetype-2776877299\mt.sock:
The file cannot be accessed by the system.
This is a known issue and we're already using a workaround for this in
pkg/kubelet/util/util_windows.go.
This commit fixes this issue for GetFileType on Windows.
When size limit is specified subsequent invocations will fail because
ibytes is changed to -1 and stored internally in quotaSizeMap during the
first call. Later invocation will see that the requested size doesn't
match the actual stored value and it will fail.

The function does not necessarily choose class based on the creation
timestamp but can also pick alphabetically first if the timestamps are
equal. The info message should not say it's choosing the newest because
it is misleading.
Now KEP-127 relies on idmap mounts to do the ID translation and we won't
do any chowns in the kubelet.
This patch just removes the usage of GetHostIDsForPod() in
operationexecutor to do the chown, and also removes the
GetHostIDsForPod() method from the kubelet volume interface.

File system quota monitoring setup fails on subsequent invocations,
each time quota setup is invoked a new random UID is generated for
each pod and compared with the previously stored UID for the folder.
Fix it by keeping track of mapping between internal uid generated
for a pod and actual external pod uid.

When a block device, say /dev/sdc, is unexpectedly disconnected from a node,
the corresponding backing file path found at /sys/block/loop*/backing_file gets
a "(deleted)" suffix. This patch trims that suffix out, allowing the Kubelet to
unmount the volume correctly.
