Actually, if you are looking for where interrupts were disabled last before triggering the "sleeping function called from invalid context", lockdep, not ftrace, would be your better bet. Enable lockdep with CONFIG_PROVE_LOCKING. It will give you better information about where the last irq was disabled. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
