}
```

The following flags are defined:

```
const (
 FreeVersion = 1 << 0
 UsesDataDir = 1 << 1
 InlineData  = 1 << 2
)
```

The "Metadata" section contains a single version, encoded in similar fashion as each version in the `Versions` array
of the previous version.

## Inline Data

func (x xlMetaV2VersionHeader) FreeVersion() bool {
	return x.Flags&xlFlagFreeVersion != 0
}

// UsesDataDir returns true if this object version uses its data directory for
// its contents and false otherwise.
func (x xlMetaV2VersionHeader) UsesDataDir() bool {
	return x.Flags&xlFlagUsesDataDir != 0
}

// InlineData returns whether inline data has been set.

	trimmed[len(trimmed)-10] += 10
	if err := xl2.Load(trimmed); err == nil {
		t.Fatal("metadata corruption not detected")
	}
}

// TestUsesDataDir tests xlMetaV2.UsesDataDir
func TestUsesDataDir(t *testing.T) {
	vID := uuid.New()
	dataDir := uuid.New()
	transitioned := make(map[string][]byte)
	transitioned[ReservedMetadataPrefixLower+TransitionStatus] = []byte(lifecycle.TransitionComplete)
