The first interrupt_status.fetch_or() operation already sets the appropriate bit; calling fetch_or() again with the same value is unnecessary. In addition, if the interrupt_status field has any bit set (not just the USED_RING bit), then the interrupt is already pending and we don't need to trigger it again.
