## Changes by Kind

### Deprecation

- Ginkgo.Measure has been deprecated in Ginkgo V2, switch to use gomega/gmeasure instead ([#111065](https://github.com/kubernetes/kubernetes/pull/111065), [@chendave](https://github.com/chendave)) [SIG Autoscaling and Testing]

### API Change

		for i, disk := range disks {
			writers[i] = newBitrotWriter(disk, "", "testbucket", "testobject", erasure.ShardFileSize(test.size), test.algorithm, erasure.ShardSize())
		}
		_, err = erasure.Encode(t.Context(), bytes.NewReader(data), writers, buffer, erasure.dataBlocks+1)
		closeBitrotWriters(writers)
		if err != nil {
			t.Fatalf("Test %d: failed to create random test data: %v", i, err)
