It's not nicer to people reading the code and wondering why, or to people who use it as a module and execute less-well-tested code paths, and I doubt it's a significant addition to boot time to do things in the normal way. I'm not particularly worried about the code going on strike because we're not being "nice" to it. -Scott -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
