I don't see this in v6.6.29.
The function that it adds is called, but doesn't exist however:
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't call gettimeofday()");
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't set timer");
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't call gettimeofday()");
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't create timer");
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't call gettimeofday()");
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't set timer");
stable/linux-6.6.y:tools/testing/selftests/timers/posix_timers.c: ksft_perror("Can't call gettimeofday()");
We should probably have this added to linux-6.6.y.
