  struct uts_namespace {
          struct kref kref;
          struct new_utsname name;
          struct user_namespace *user_ns;
          struct ucounts *ucounts;
          struct ns_common ns;
  } __randomize_layout;

Right -- that's a good example.  Run "gdb vmlinux" on both vmlinux files,
enter "ptype struct uts_namespace", and compare the two.
