Notice that there are a lot of Patch commits to enhance the consistency of output from our legacy tests, we plan to refactor them using kselftest_harness.h automatically by tools. This will help standardize the TAP output format, ensuring clarity and traceability of test results. This is the version of tmpfs after auto-refactoring.
