Worked on the geerlingguy/linux repository to address a critical kernel stability issue by fixing a memory allocation bug in the EDMA driver. Focused on correcting the allocation size for the queue_priority_map on ARM platforms, the solution prevented out-of-bounds writes that previously led to kernel crashes and memory corruption. Applied strong debugging and code review skills to identify the root cause and implement a targeted patch, enhancing DMA reliability in production environments. Utilized C programming and kernel development expertise, with a particular emphasis on memory management, to deliver a robust fix that improved overall system stability without introducing new features.
