please use BUILD_BUG_ON instead.

Can you reorder the code to avoid all these forward declarations please?

This looks very odd.

This is a very odd paramater interface. We really don't want drivers to use module_param_call directly. You probably want various module_param_array calls instead. - 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/
