- * @kstat_irqs: irq stats per cpu
- * @handle_irq: highlevel irq-events handler
- * @preflow_handler: handler called before the flow handler (currently used by sparc)
- * @action: the irq action chain
- * @status: status information
- * @core_internal_state__do_not_mess_with_it: core internal status information
- * @depth: disable-depth, for nested irq_disable() calls
- * @wake_depth: enable depth, for multiple irq_set_irq_wake() callers
- * @irq_count: stats field to detect stalled irqs
- * @last_unhandled: aging timer for unhandled count
- * @irqs_unhandled: stats field for spurious unhandled interrupts
- * @lock: locking for SMP
- * @affinity_hint: hint to user space for preferred irq affinity
- * @affinity_notify: context for notification of affinity changes
- * @pending_mask: pending rebalanced interrupts
- * @threads_oneshot: bitfield to handle shared oneshot threads
- * @threads_active: number of irqaction threads currently running
- * @wait_for_threads: wait queue for sync_irq to wait for threaded handlers
- * @dir: /proc/irq/ procfs entry
- * @name: flow handler name for /proc/interrupts output
