+There're some scenarios that the failure could be resolved, one example is an existing running pod gets a label update and becomes matching a Pod affinity.
+For this scenario, the `InterPodAffinity` plugin's `QueuingHint` callback function checks every Pod label update that occurs in the cluster.

 plugin's `QueuingHint` prompts the scheduling queue to move `pod-a` back into the ActiveQ or
 the BackoffQ component.
