[Kernel-packages] [Bug 1928522] Re: seccomp_bpf from ubuntu_kernel_selftests.seccomp in linux ADT test failure with linux/4.15.0-144.148

So, s390x ptrace does allow to set the syscall and return code as long as it sets the return code at exit time. However, when using seccomp SECCOMP_RET_TRACE, there is no possibility to change it at exit time (by doing a ptrace after SECCOMP_RET_TRACE stops the process). It only happens at entry
