Cover letter [PATCH v1 0/2] genirq: support multiple IRQ notifier.
Each irq_desc only supports one IRQ affinity notifier at current implementation so when we try to register another notifier, it silently unregister previous entry and register new one.
However the problem is that if CONFIG_RFS_ACCEL is set, at current implementation no way to set additional IRQ affinity notifier for some NIC cards RFS enabled because it already used for RFS. With this patch we can register multiple IRQ affinity notifiers.
