Worked on the Samsung/TizenRT repository to address a critical bug in the ROMFS file system, focusing on hard-link path resolution. Using C programming and file system development expertise, implemented a targeted fix that corrected stale buffered information encountered when following hard links, ensuring accurate offset usage during directory traversal. This solution improved the reliability and predictability of path resolution across ROMFS-mounted directories, reducing random errors and maintaining consistent filesystem metadata after linking operations. The work involved thorough validation against typical ROMFS usage scenarios and demonstrated strong debugging skills, precise patching in a Git-based workflow, and effective cross-team communication.
