A Dirqflags-tracing.rst3 :Original: Documentation/core-api/irq/irqflags-tracing.rst
9 .. _cn_irqflags-tracing.rst:
17 “irq-flags tracing”（中断标志追踪）功能可以 “追踪” hardirq和softirq的状态，它让
27 的状态变化。但是一个架构可以以一种相当直接且无风险的方式启用irq-flags-tracing。
33 然后还需要做一些功能上的改变来实现对irq-flags-tracing的支持:
45 一般来说，在一个架构中，不完整的irq-flags-tracing实现是没有风险的：lockdep
46 会检测到这一点，并将自己关闭。即锁验证器仍然可靠。应该不会因为irq-tracing的错
