dc52b69ddc Only lock statuses map when status isn't successful 
Determine the status successful or not first, that will reduce the chance
of lock contention.

Merge pull request #92797 from ahg-g/ahg-prefilter 
Return a FitError when PreFilter fails with unschedulable status

ff3e5e06a7 GenericEphemeralVolume: initial implementation 
The implementation consists of
- identifying all places where VolumeSource.PersistentVolumeClaim has
  a special meaning and then ensuring that the same code path is taken
  for an ephemeral volume, with the ownership check
- adding a controller that produces the PVCs for each embedded
  VolumeSource.EphemeralVolume
- relaxing the PVC protection controller such that it removes
  the finalizer already before the pod is deleted (only
  if the GenericEphemeralVolume feature is enabled): this is
  needed to break a cycle where foreground deletion of the pod
  blocks on removing the PVC, which waits for deletion of the pod

The controller was derived from the endpointslices controller.
