Worked on the geerlingguy/linux repository to enhance the Linux kernel’s block layer, focusing on stability, performance, and deadlock prevention in I/O scheduling and block QoS management. Addressed module reference leaks and improved elevator context switching by centralizing scheduler tag management and refining memory handling. Optimized the block QoS path for multiplexed and multipath configurations, simplifying completion logic and ensuring correctness during topology changes. Used C programming and low-level concurrency control techniques to mitigate deadlock risks, including replacing static keys with per-queue flags. The work emphasized robust system programming practices and contributed to more reliable kernel-level block device management.
