Hi all, After merging the kunit-next tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from drivers/gpu/drm/tests/drm_buddy_test.c:7: drivers/gpu/drm/tests/drm_buddy_test.c: In function 'drm_test_buddy_alloc_range_bias': drivers/gpu/drm/tests/drm_buddy_test.c:191:40: error: format '%u' expects a matching 'unsigned int' argument [-Werror=format=] 191 | "buddy_alloc failed with bias(%x-%x), size=%u, ps=%u\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/kunit/test.h:597:37: note: in definition of macro '_KUNIT_FAILED' 597 | fmt, \ | ^~~ include/kunit/test.h:662:9: note: in expansion of macro 'KUNIT_UNARY_ASSERTION' 662 | KUNIT_UNARY_ASSERTION(test, \ | ^~~~~~~~~~~~~~~~~~~~~ include/kunit/test.h:1233:9: note: in expansion of macro 'KUNIT_FALSE_MSG_ASSERTION' 1233 | KUNIT_FALSE_MSG_ASSERTION(test, \ | ^~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/tests/drm_buddy_test.c:186:17: note: in expansion of macro 'KUNIT_ASSERT_FALSE_MSG' 186 | KUNIT_ASSERT_FALSE_MSG(test, | ^~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/tests/drm_buddy_test.c:191:91: note: format string is defined here 191 | "buddy_alloc failed with bias(%x-%x), size=%u, ps=%u\n", | ~^ | | | unsigned int cc1: all warnings being treated as errors Caused by commit 806cb2270237 ("kunit: Annotate _MSG assertion variants with gnu printf specifiers") interacting with commit c70703320e55 ("drm/tests/drm_buddy: add alloc_range_bias test") from the drm-misc-fixes tree. I have applied the following patch for today (this should probably actually be fixed in the drm-misc-fixes tree).
