It looks like this backport is pretty old. I am a bit confused why this happens till now.
I can reproduce this even with linux_4.4.0-210: apt-get source --download-only linux-modules-4.4.0-210-generic dpkg-source -x linux*dsc linux cd linux/tools/testing/selftests/ make TARGETS=timers But when I looking s2024.12.02, x/linux with 4.4.0-263.297 does not have this timer-build task. We don't have any change in autotest-client-test for this. -- You received this bug notification because you are a member of Canonical Platform QA Team, which is subscribed to ubuntu-kernel-tests. https://bugs.launchpad.net/bugs/2098848 Title: raw_skew test in kernel selftests for timers fails to build Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Invalid Status in linux source package in Xenial: Triaged Bug description: timers/raw_skew subtest from kernel selftests fails to build on xenial: 17:30:43 DEBUG| [stdout] make[1]: Entering directory '/home/ubuntu/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/timers' 17:30:43 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread posix_timers.c -o posix_timers 17:30:44 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread nanosleep.c -o nanosleep 17:30:44 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread nsleep-lat.c -o nsleep-lat 17:30:44 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread set-timer-lat.c -o set-timer-lat 17:30:45 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread mqueue-lat.c -o mqueue-lat 17:30:45 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread inconsistency-check.c -o inconsistency-check 17:30:45 DEBUG| [stdout] gcc -O3 -Wl,-no-as-needed -Wall -DKTEST -lrt -lpthread raw_skew.c -o raw_skew 17:30:45 ERROR| [stderr] raw_skew.c: In function ‘main’: 17:30:45 ERROR| [stderr] raw_skew.c:152:11: error: too many arguments to function ‘ksft_exit_skip’ 17:30:45 ERROR| [stderr] return ksft_exit_skip("The clock was adjusted externally.

We picked up the faulty backport with a stable update for xenial: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798587 In 4.19, as opposed to 4.4 where ksft_exit_skip() does not take any arguments, the function is defined as static inline int ksft_exit_skip(const char *msg, ...) The backport of the patch should not pass a string to the function.
