During August 2025, Makb worked on the geerlingguy/linux repository, focusing on kernel development and system programming using C. He addressed a reliability issue in the kexec image loading process by implementing support for the KEXEC_FILE_NO_CMA flag in kexec_file_load. This technical change allowed userspace to disable Contiguous Memory Allocator (CMA) allocations when loading kexec images, enabling CMA-free loading and reducing deployment errors during live updates. By fixing the flag legality and ensuring proper handling in the kernel, Makb improved the robustness of kexec-based workflows. The work demonstrated depth in low-level systems engineering and kernel interface design.
