To clarify this, rename it to DECLARE_EVENT_CLASS, which follows the various 'DECLARE_*()' idioms we already have in the kernel: DECLARE_EVENT_CLASS(class) DEFINE_EVENT(class, event1) DEFINE_EVENT(class, event2) DEFINE_EVENT(class, event3) To complete this logic we should also rename TRACE_EVENT() to: DEFINE_SINGLE_EVENT(single_event) ... but in a more quiet moment of the kernel cycle.
