Worked on the geerlingguy/linux repository to enhance kernel and bootloader reliability by addressing a bug in the kexec image loading process. Focused on kernel development and system programming using C, the work involved implementing support for the KEXEC_FILE_NO_CMA flag within the kexec_file_load function. 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 legality check for this flag, the update improved the robustness of kexec-based workflows and contributed to more reliable system updates in production environments.
