Some general debugging features like kmemleak, KASAN, lockdep, UBSAN etc help fix many viruses like a microscope. On the other hand, those features are scatter around and mixed up with more situational debugging options making them difficult to consume properly. This cold help amplify the general debugging/testing efforts and help establish sensitive default values for those options across the broad. This could also help different distros to collaborate on maintaining debug-flavored kernels. The config is based on years' experiences running daily CI inside the largest enterprise Linux distro company to seek regressions on linux-next builds on different bare-metal and virtual platforms. It can be used for example, $ make ARCH=arm64 defconfig debug.config Since KASAN and KCSAN can't be enabled together, we will need to create a separate one for KCSAN later as well.
