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/iommu/iommufd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/iommu/iommufd.c b/tools/testing/selftests/iommu/iommufd.c index ca2b35e9d443a..c4d4f3659626e 100644 --- a/tools/testing/selftests/iommu/iommufd.c +++ b/tools/testing/selftests/iommu/iommufd.c @@ -2154,7 +2154,7 @@ FIXTURE_SETUP(iommufd_dirty_tracking) rc = posix_memalign(&self->buffer, HUGEPAGE_SIZE, mmap_buffer_size); if (rc || !self->buffer) { - SKIP(return, "Skipping buffer_size=%lu due to errno=%d", + SKIP(return, "Skipping buffer_size=%zu due to errno=%d", mmap_buffer_size, rc); } assert((uintptr_t)self->buffer % HUGEPAGE_SIZE == 0); -- 2.53.0
