Hi there, 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. Since I have been deal with those options on a daily basis for the last a few years and accumulated the knowledge of their pros and cons, I am thinking about to create an initial "make debugconfig" target, so that it could amplify the general debugging/testing efforts and help establish sensitive default values for those options across the broad. The idea is to have a debugconfig inside kernel/configs/ and update scripts/kconfig/Makefile and Documentation/admin-guide/README.rst accordingly. I am still trying to figure out a few implementation details like how to convert an existing .config to debugconfig, but want to gather some feedback before I dive in too deep.
