optimize adc.nodeUpdate(). Time complexity reduced from O(n) to O(1), where n is the number of nodes.
Data stored in nodeAttachedTo.mountedByNode is now at actualStateOfWorld.inUseVolumes.
This refactor also ensures that we can record the state update even if the volume is not present in ASW yet.
The added BenchmarkNodeUpdate result is reduced from 28076923 to 16030 ns/op.
The previous BenchmarkPopulateActualStateOfWorld result is also reduced from 13s to 8s.
- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value
The informer is not initialized, so no assertion performed before. Fixed this now.
Then fixed the test failure by using NewAttachDetachController to initialize adc.
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.
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.
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.

Add a new call to VolumePlugin interface and change all its
implementations.
Kubelet's VolumeManager will be interested whether a volume supports
mounting with -o conext=XYZ or not to hanle SetUp() / MountDevice()
accordingly.
