Worked on the linux-test-project/ltp repository to enhance the reliability of automated Linux testing by addressing a persistent issue in the cpuset_memory_spread_test environment. Using Shell scripting and system administration skills, implemented a cleanup mechanism that removes stale FIFO files before recreating them when a cgroup mount fails. This approach prevented blocked test runs and reduced setup failures, directly improving the stability of continuous integration pipelines. The solution was verified across multiple CI runs, demonstrating proficiency in testing and cgroup management. The work focused on robust error handling and cleanup logic, resulting in faster feedback cycles and more dependable test environments.
