2d9d84dc64 Merge pull request #32888 from deads2k/client-10-fixup-remaining-listers 
Automatic merge from submit-queue

simplify RC and SVC listers

Make the RC and SVC listers use the common list functions that more closely match client APIs, are consistent with other listers, and avoid unnecessary copies.

821ff657f9 Merge pull request #27199 from derekwaynecarr/disk_eviction 
Automatic merge from submit-queue

Initial support for pod eviction based on disk

This PR adds the following:

1. node reports disk pressure condition based on configured thresholds
1. scheduler does not place pods on nodes reporting disk pressure
1. kubelet will not admit any pod when it reports disk pressure
1. kubelet ranks pods for eviction when low on disk
1. kubelet evicts greediest pod

Follow-on PRs will need to handle:

1. integrate with new image gc PR (https://github.com/kubernetes/kubernetes/pull/27199)
1. container gc policy should always run (will not be launched from eviction, tbd who does that)
  1. this means kill pod is fine for all eviction code paths since container gc will remove dead container
1. min reclaim support will just poll summary provider (derek will do follow-on)
1. need to know if imagefs is same device as rootfs from summary (derek follow-on)

Check nil pointer in predicates.go

Should check if the pointer is nil in func filterVolumes as is done in [func predicate](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/algorithm/predicates/predicates.go#L279).

No need to log empty string in predicates.go

If `pvcName` is empty, we don't need to log it.

c9a60e2d2c Rephrase 'pv not found in cache' warnings. 
When kubelet starts a pod that refers to non-existing PV, PVC or Node, it
should clearly show that the requested element does not exist.

Previous "PersistentVolumeClaim 'default/ceph-claim-wm' is not in cache"
looks like random kubelet hiccup, while "PersistentVolumeClaim
'default/ceph-claim-wm' not found" suggests that the object may not exist at
all and it might be an user error.

Fixes #27523
