> {{ReplicaInfo#unlinkBlock()}} is effectively disabled by the following code,
> because {{isUnlinked()}} always returns true.
> {code}
> if (isUnlinked()) {
> return false;
> }
> {code}
> Several test cases, e.g., {{TestFileAppend#testCopyOnWrite}} and
> {{TestDatanodeRestart#testRecoverReplicas}} are testing against the unlink
> Lets remove the relevant code to eliminate the confusions.
