One other problem is that you need CONFIG_TRACE_IRQFLAGS (is that a lockdep or just trace feature?) to use any tracer since the tracing_cpumask file is always created for all tracer. This file has tracing_cpumask_write() as a write operation, and this func uses raw_local_funcs.... Perhaps we should disable the tracing_cpu_mask related things if TRACE_IRQFLAGS in not configured? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
