Worked on the linux-test-project/ltp repository, focusing on enhancing the reliability of kernel testing through targeted bug fixes in C. Addressed a critical issue in the io_control01 test by updating the device selection logic to require an exact match of both major and minor device numbers, thereby preventing incorrect device matches and improving test accuracy. Applied a patch to ensure correct rbyte handling in io.read, further strengthening the test suite’s correctness. Emphasized code quality and validation throughout the process, leveraging expertise in C programming and kernel testing to deliver more robust and dependable continuous integration for the project.
