- Kubeadm: fixed an etcd learner-mode bug by preparing an etcd static pod manifest before promoting ([#115038](https://github.com/kubernetes/kubernetes/pull/115038), [@tobiasgiese](https://github.com/tobiasgiese))

    dispatcher.maxRequests = 1
    client.newCall(request1).enqueue(callback)
    executor.shutdown()
    client.newCall(request2).enqueue(callback)
    dispatcher.maxRequests = 2 // Trigger promotion.
    callback.await(request2.url).assertFailure(InterruptedIOException::class.java)
    assertThat(listener.recordedEventTypes())
      .containsExactly("CallStart", "CallStart", "CallFailed")
  }
