FYI, we noticed the following commit (built with gcc-7):
commit: cd5bbb3047bf73353767d70a03db986600ca372a ("ptrace: add PTRACE_GET_SYSCALL_INFO request")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master
in testcase: kernel_selftests
with following parameters:
group: kselftests-02
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 8G
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag

The syscall entry/exit is now exposed via PTRACE_GETEVENTMSG,
update the test accordingly.
