Worked on the geerlingguy/linux repository to enhance CIFS client reliability and cache management within the Linux kernel. Addressed dynamic network environments by refining channel management, ensuring interface weights reset properly to support retries and correct channel allocation after server interface changes. Improved cache eviction logic by introducing a last_access_time field to cached file identifiers, allowing the system to prioritize recently accessed directories and prevent premature cleanup of active data. These changes, implemented in C with a focus on kernel development, caching, and networking, contributed to greater stability, reduced user-facing errors, and more efficient file system operations in complex network scenarios.
