We don't use module refcounts at all anymore for netdev objects. That's the whole key. Module refcounts are spurious when a subsystem does it's own sane accounting and uses strictly dynamically allocated objects. - 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/
