Signed-off-by: Sasha Levin --- Found with a 32-bit build of the selftests with a 64-bit time_t (gcc 16 and clang 21 with -m32 -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64); KernelCI's 32-bit arm builds show the same warnings. The changed files build without format warnings there now, and the x86_64 builds don't change. The other selftests get the same kind of fix in separate patches. tools/testing/selftests/dmabuf-heaps/dmabuf-heap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/dmabuf-heaps/dmabuf-heap.c b/tools/testing/selftests/dmabuf-heaps/dmabuf-heap.c index 1d49df6719198..c65efc088e88d 100644 --- a/tools/testing/selftests/dmabuf-heaps/dmabuf-heap.c +++ b/tools/testing/selftests/dmabuf-heaps/dmabuf-heap.c @@ -212,7 +212,7 @@ static void test_alloc_zeroed(char *heap_name, size_t size) void *p = NULL; char *c; - ksft_print_msg("Testing alloced %ldk buffers are zeroed:\n", size / 1024); + ksft_print_msg("Testing alloced %zuk buffers are zeroed:\n", size / 1024); heap_fd = dmabuf_heap_open(heap_name); /* Allocate and fill a bunch of buffers */ -- 2.53.0
