sigaction provides the irq# -- so if you want that information, use the
sigaction interface. I'd rather make the RTLinux environment
look like Posix threads than like the interior of the Linux kernel.
The interior Linux kernel is much more complex, much less familiar, and
guaranteed to be not stable. I think it is a fundamental error to use
Linux internal operations as an API.
But I don't see the problem even with the rtl_request_irq interface.
After all, it is a one line function to provide the functionality
you want. Am I missing something? Maybe you can give me an example.
