If anyone has any objections, please let me know. ------------------ From: Maciej Wieczor-Retman [ Upstream commit 4d7f4e8158b62f63031510cdc24acc520956c091 ] Compiling pidfd selftest after adding a __printf() attribute to ksft_print_msg() and ksft_test_result_pass() exposes -Wformat warnings in error_report(), test_pidfd_poll_exec_thread(), child_poll_exec_test(), test_pidfd_poll_leader_exit_thread(), child_poll_leader_exit_test(). The ksft_test_result_pass() in error_report() expects a string but doesn't provide any argument after the format string. All the other calls to ksft_print_msg() in the functions mentioned above have format strings that don't match with other passed arguments. Fix format specifiers so they match the passed variables. Add a missing variable to ksft_test_result_pass() inside error_report() so it matches other cases in the switch statement.
