Out of curiosity, what effect would the following > have on top of 1b738f196e? I applied the patch upon 1b738f196e (as below fec356fd0c), but seems less useful. (I also rebuild and rerun 1b738f196e and its parent since we have some config updates, now 3 commits are built with same config, as attached. since rerun, you would see the data have some difference for 1b738f196e and its parent, but similar as before) for stress-ng (full comparison as below [1]): =========================================================================================
