[PATCH] selftest/futex: fix format-security warnings in futex_priv_hash
From: Nai-Chen Cheng
Date: Thu Jul 17 2025 - 08:08:17 EST
Fix format-security warnings by using proper format strings when
passing message variables to ksft_exit_fail_msg(),
ksft_test_result_pass(), and ksft_test_result_skip() function.
This prevents potential security issues and eliminates compiler warnings
when building with -Wformat-security.
