Its filename is lib-tests-convert-test_uuid-module-to-kunit.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/lib-tests-convert-test_uuid-module-to-kunit.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Ryota Sakamoto Subject: lib/tests: convert test_uuid module to KUnit Date: Mon, 15 Dec 2025 13:43:22 +0000 Move lib/test_uuid.c to lib/tests/uuid_kunit.c and convert it to use KUnit. This change switches the ad-hoc test code to standard KUnit test cases. The test data remains the same, but the verification logic is updated to use KUNIT_EXPECT_* macros. Also remove CONFIG_TEST_UUID from arch/*/configs/* because it is no longer used. The new CONFIG_UUID_KUNIT_TEST will be automatically enabled by CONFIG_KUNIT_ALL_TESTS.
