Level 4 is mean for debug operations.
The default level use to be level 2, on clusters with a lot of
Services this means that the kube-proxy will generate a lot of
noise on the logs, with the performance penalty associated to
it.
Device Plugins that wish to leverage the Topology Manager can send back a populated
TopologyInfo struct as part of the device registration, along with the device IDs
and the health of the device. TopologyInfo is converted to TopologyHints and
used by TopologyManager to find the optimal/desired resource allocation for a Pod.
If a plugin sends an empty but non-nil instance of TopologyInfo for a resource,
devicemanager passes it on as an empty instance of TopologyHint which is
currently interpreted as "Hint Provider has no possible NUMA affinities
for resource" which further means that pods requesting that resource will fail.
To not block device resources that pass TopologyInfo{Nodes:[]*NUMANode{}} from being
used, interprete that as nil set of hints and not a []TopologyHint{}.

Hi team, hope u all doing well.
I have checked TODO that to remove "retry" if feasible but it's important i think that it shouldn't be removed because it was used in every file on your repo.
Update idempotency.go

When Ginkgo shows a BeforeEach/AfterEach/DeferCleanup, then it can only show
the source code where the callback was registered because there is no
description parameter. This can be improved by passing a custom CodeLocation.
Because a description like "set up framework" might not be enough, the source
code is still shown, too.
SharedInformerFactory starts goroutines in Start and those can be stopped by
closing the stop channel. However, there was no API that waits for the
goroutines.
This is a problem for unit testing. A test has to return while the informers
are still running, which may get flagged by tools like
https://github.com/uber-go/goleak or by klog/ktesting when those informers
lead to log output.
While at it, more documentation gets added to address
https://github.com/kubernetes/kubernetes/issues/65036.
This `DeploymentSpec` struct is used internally; the ones used for
serialization do have a pointer and this text was most likely copied
from there and not corrected.

This is useful for running a driver on a subset of all ready nodes:
- use e2enode.GetBoundedReadySchedulableNodes with a suitable
maximum number of nodes to determine how much nodes are available
for a test
- define pod anti-affinity in the PodTemplate:
affinity:
podAntiAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchLabels:
app.kubernetes.io/instance: xxxxxxx
topologyKey: kubernetes.io/hostname
- set the ReplicaSetSpec.Replicas value to the number of nodes
