Because we are back to the solution used in Linux 1.2. I have to maintain the
table of devices assigned to interrupts. This is so general functionality,
that should be provided by the OS.
I agree that doing such lookup (irq->dev_id) uses some time. So what about
providing a macro which could be called in RT-ISR
get_device_id()
?
So, registration routine should save device_id and name somewhere. But
getting this information in RT-ISR would by optional - no performance
penalty if not used. What about such solution?

I do not understand relation of sigaction to interrupts.
