During August 2025, Darwi focused on streamlining header management in the geerlingguy/linux repository by consolidating CPUID-related headers. He removed the transitional <asm/cpuid.h> wrapper and migrated all relevant code to the new <asm/cpuid/api.h> interface, reducing redundant code paths and aligning with the project’s header hygiene objectives. This work, implemented in C and centered on kernel development and system headers management, aimed to simplify ongoing maintenance and improve code clarity. While the scope was limited to a single feature and did not involve bug fixes, the changes demonstrated careful attention to maintainability and consistency within the kernel codebase.
