Worked on the DragonOS-Community/DragonOS repository to enhance sysfs attribute group management, focusing on safety and reliability within the kernel’s filesystem layer. Developed and delivered a feature in Rust that introduced the group_remove_files function, enabling safe removal of attribute groups in sysfs. This approach ensured that group directories were properly deleted while preventing accidental removal of sibling directories, thereby maintaining filesystem integrity and reducing the risk of unintended data loss during device tree and attribute group updates. Emphasized clear commit messages and sign-offs to support maintainability and efficient code review, leveraging skills in Rust programming, filesystem, and kernel development.
