It would be nice to express those dependencies in some clearer and less fragile manner than link order. I guess finer-grained initcall levels would do that, but it doesn't scale very well.
But whatever. I think multithreaded probing just doesn't pass the benefit-versus-hassle test, sorry. Make it dependent on CONFIG_GREGKH ;) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
