struct. This is used for keeping the payload of the interrupts. Multiple different interrupts can be pending and most of them have payload - we want to keep everything.
Now, looking at that code again, as I/O is floating and emergency is also handled via a separate bitmap we could get rid of these two in a follow-up patch. Jens, can you have a look and prepare a followup-cleanup if appropriate?
