The uffd_test_start() is perhaps a little too elaborate about how it dispatches tests, leading to a clang warning that looks roughly like this:
"uffd-unit-tests.c:1198:20: warning: format string is not a string literal (potentially insecure) [-Wformat-security] ...note: treat the string as an argument to avoid this. uffd_test_start(test_name); "
However, it doesn't seem worth it to rewrite the way uffd_test_start() works, given that these tests are already deeply unsafe to begin with.
Fix this by just disabling the compiler warning, but only for uffd-unit-tests.
