The dmesg on 4.20 rc6 still contains a lot of call traces. I don't know if they are the same ones or of the same origin though. When comparing files i initially thought the 4.20rc6 has less call traces, but actually at the end of the diff there are more. So i would say both 4.18 and 4.20rc6 roughly have the same amount of call traces.
