From 86d2a2f51fbada84e377665df06b5a479a1edc99 Mon Sep 17 00:00:00 2001 From: Bitao Hu Date: Thu, 11 Apr 2024 15:41:30 +0800 Subject: genirq: Convert kstat_irqs to a struct The irq_desc::kstat_irqs member is a per-CPU variable of type int, which is only capable of counting. A snapshot mechanism for interrupt statistics will be added soon, which requires an additional variable to store the snapshot. To facilitate expansion, convert kstat_irqs here to a struct containing only the count.
