------------------------------------------------------ From: Wladislav Wiebe wladislav.kw@gmail.com Subject: tools/mm: -Werror fixes in page-types/slabinfo Date: Tue, 22 Oct 2024 19:21:13 +0200

Commit e6d2c436ff693 ("tools/mm: allow users to provide additional cflags/ldflags") passes now CFLAGS to Makefile. With this, build systems with default -Werror enabled found:

slabinfo.c:1300:25: error: ignoring return value of 'chdir' declared with attribute 'warn_unused_result' [-Werror=unused-result] ������������������������������������������������ chdir(".."); ������������������������������������������������ ^~~~~~~~~~~ page-types.c:397:35: error: format '%lu' expects argument of type 'long unsigned int', but argument 2 has type 'uint64_t' {aka 'long long unsigned int'} [-Werror=format=] ������������������������������������������������ printf("%lu\t", mapcnt0); ���������������������������������������������������������������� ~~^�������� ~~~~~~~ ..

Fix page-types by using PRIu64 for uint64_t prints and check in slabinfo for return code on chdir("..").
