In lttng-tools-2.2.0\src\bin\lttng-sessiond\main.c, we have:

The lines:

    fprintf(stderr, "      --no-kernel                    Disable kernel tracer\n");

should thus become:

    fprintf(stderr, "  -C, --kconsumerd-cmd-sock PATH     Specify path for the kernel consumer command socket\n");

...
    fprintf(stderr, "  -Z, --verbose-consumer             Verbose mode for consumer. Activate DBG() macro.\n");
    fprintf(stderr, "  -N, --no-kernel                    Disable kernel tracer\n");
