Subject: [PATCH] memblock tests: fix unknown macro build error
Date: Mon, 22 Dec 2025 10:15:43 +0300	[thread overview]
Message-ID: <20251222071543.953823-1-dmantipov@yandex.ru> (raw)

Running 'make CC=clang' under tools/testing/memblock, I've
noticed the following:

clang -I. -I../../include -Wall -O2 -fsanitize=address -fsanitize=undefined \
      -D CONFIG_PHYS_ADDR_T_64BIT   -c -o memblock.o memblock.c
memblock.c:783:44: error: use of undeclared identifier 'SZ_1M'
  783 |                 mem_size_mb = memblock_phys_mem_size() / SZ_1M;
      |                                                          ^~~~~
memblock.c:785:37: error: use of undeclared identifier 'SZ_1M'
  785 |                        (nr_pages << PAGE_SHIFT) / SZ_1M, mem_size_mb);
      |                                                   ^~~~~

So just include linux/sizes.h from the linux/kernel.h stub.
