This is one of just 3 remaining "Test Module" kselftests (the others being bitmap and printf), the rest having been converted to KUnit. In addition to the enclosed patch, please consider this an RFC on the removal of the "Test Module" kselftest machinery.
I tested this using: $ tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 scanf Signed-off-by: Tamir Duberstein <tam...@gmail.com> --- Changes in v4: - Bake `test` into various macros, greatly reducing diff noise. - Revert control flow changes. - Link to v3: https://lore.kernel.org/r/20250204-scanf-kunit-convert-v3-0-386d7c3ee...@gmail.com Changes in v3: - Reduce diff noise in lib/Makefile. (Petr Mladek) - Split `scanf_test` into a few test cases.
