Without using StopGetStore, get hits on the in-flight cache would propagate as puts to subsequent nodes in the hierarchy. Since the in-flight cache is only used as temporary storage while a put is in flight, this caused duplicates of the in-flight puts, which manifests as move collision log spam from the file system cache store.
