    There's a minor bug in it. Syscalls are numbered from zero, so there's
    __NR_syscall_max + 1 of them. Patch attached.
    Nonetheless the latency tracing still doesn't work for me on x86_64. It
    compiles but hotplug starts to segfault in an infinite loop during
    booting up. When I disable CONFIG_LATENCY_TRACE, it works.
