It's not my job to do your work for you! I gave you hints on how you can do this with attaching to existing trace events and your response was "If you don't think it's hard, go ahead and show us." No! I'm too busy with my own work to do free work for you! https://lore.kernel.org/all/20220905235007.sc4uk6illlog62fl@kmo-framework/ I know it's easier to create something from scratch that you fully know, than to work with an existing infrastructure that you need to spend effort and learn to make it do what you want. But by recreating the work, you now pass the burden onto everyone else that needs to learn what you did. Not to mention, we would likely have multiple ways to do the same thing. Sorry, but that's not how an open source community is suppose to work. -- Steve
