Worked on improving the reliability of continuous integration pipelines for the linux-test-project/ltp repository by addressing test flakiness related to the ustat system call on Btrfs file systems. Developed a targeted mechanism in C that leverages the LTP library’s .skip_filesystems feature to conditionally bypass ustat tests when running on Btrfs, thereby preventing false negatives and ensuring accurate test results for other file systems. Focused on kernel development, system programming, and testing, the solution was validated through CI runs that confirmed the intended behavior. This work enhanced the stability and trustworthiness of automated testing environments for the project.
