- This is the feature to add tracepoint for tracking down page reference
- manipulation. This tracking is useful to diagnosis functional failure
- due to migration failure caused by page reference mismatch. Be
- careful to turn on this feature because it could bloat some kernel
- text. In my configuration, it bloats 30 KB. Although kernel text will
- be bloated, there would be no runtime performance overhead if
- tracepoint isn't enabled thanks to jump label.
