6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej Wieczor-Retman <maciej.wieczor-retman@xxxxxxxxx>
[ 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.
Fixes: 2def297ec7fb ("pidfd: add tests for NSpid info in fdinfo")
