two errors - what are they?

and my script is:

probe kernel.function("*@mm/swapfile.c").call {
        printf ("%s -> %s\n", thread_indent(1), probefunc())
        print_backtrace();
        printf("\n");
}
probe kernel.function("*@mm/swapfile.c").return {
        printf ("%s <- %s\n", thread_indent(-1), probefunc())
        printf("\n");
}

Command I used is just stap -vvvv xxxxx.stp
