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. -- Lee Jones [李琼斯]
