Functions definitions without any argument list produce a warning with -Wstrict-prototypes: vdso_test_correctness.c:111:13: warning: function declaration isn’t a prototype [-Wstrict-prototypes] 111 | static void fill_function_pointers() | ^~~~~~~~~~~~~~~~~~~~~~ Explicitly use an empty argument list.
