This version 4 patch series replace direct error handling methods with ksft macros, which provide better reporting.Currently, when the tmpfs test runs, it does not display any output if it passes,and if it fails (particularly when not run as root),it simply exits without any warning or message. This series of patch adds: 1. Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test outputs more effectively. 2. Skip if not run as root. 3. Replace direct error handling with 'ksft_test_result_*', 'ksft_print_msg' and KSFT_SKIP macros for better reporting. v3->v4: - Start a patchset - Split patch into smaller pathes to make it easy to review. Patch1 Replace 'ksft_test_result_skip' with 'KSFT_SKIP' during root run check. Patch2 Replace 'ksft_test_result_fail' with 'KSFT_SKIP' where fail does not make sense, or failure could be due to not unsupported APIs with appropriate warnings. v3: https://lore.kernel.org/all/20241028185756.111832-1-cvam0000@xxxxxxxxx/ v2->v3: - Remove extra ksft_set_plan() - Remove function for unshare() - Fix the comment style v2: https://lore.kernel.org/all/20241026191621.2860376-1-cvam0000@xxxxxxxxx/ v1->v2: - Make the commit message more clear. v1: https://lore.kernel.org/all/20241024200228.1075840-1-cvam0000@xxxxxxxxx/T/#u thanks Shivam Shivam Chaudhary (2): selftests:tmpfs: Add Skip test if not run as root selftests:tmpfs: Add kselftest support to tmpfs .../selftests/tmpfs/bug-link-o-tmpfile.c | 79 +++++++++++++++---- 1 file changed, 62 insertions(+), 17 deletions(-) -- 2.45.2
