On 32-bit architectures size_t is an unsigned int, and printing it with
%ld warns:
dmabuf-heap.c:215:43: warning: format '%ld' expects argument of type 'long
int', but argument 2 has type 'size_t' {aka 'unsigned int'} [-Wformat=]
Use %zu.

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.
