    Description

      ReplicaInfo#unlinkBlock() is effectively disabled by the following code, because isUnlinked() always returns true.

      if (isUnlinked()) {
        return false;
      }
      

      Several test cases, e.g., TestFileAppend#testCopyOnWrite and TestDatanodeRestart#testRecoverReplicas are testing against the unlink
      Lets remove the relevant code to eliminate the confusions.
