Worked on the geerlingguy/linux repository to enhance the stability and correctness of the Linux kernel scheduler by addressing a critical integer overflow issue. Focused on kernel development and system programming using C, the work involved widening the nr_uninterruptible variable from unsigned int to unsigned long, preventing load average miscalculations when handling large numbers of uninterruptible tasks. This targeted change improved the reliability of system monitoring and autoscaling under heavy I/O and blocking conditions. The solution was tightly scoped, adhering to Linux kernel coding standards, and demonstrated careful debugging and disciplined commit practices to ensure long-term maintainability and minimal regression risk.
