    Jason suggested that too, offlist.
    I pretty much agreed, but wanted to get the 1st 17 sent.

    What gave me pause was this:
    pr_debug("Unknown argument: calling %p\n", handle_unknown);

    it made me think about a common handler to deal with it 1st,
    before the /* Find parameter */ loop, so that modules couldnt hijack
    the dyndbg param, defeating the common handler.
    OTOH, the BUILD_BUG_DECL prevents that hijack.

    Maybe the best answer is silence the print when param is properly handled.

    if (handle_unknown) {
    int rc = handle_unknown(param, val);
    if (rc)
    pr_debug("Unknown argument: calling %p\n",
    handle_unknown);
    return rc;
    }

    I'll do this shortly, see how it works out..
    thanks
