So Linus' patch mostly fixes smp_call_function_single_async() which is not what you're using. It would be very good to see traces of other CPUs; if for some reason the target CPU doesn't get around to running your callback, then we'll forever wait on it. loaded_vmcs_clear() uses smp_call_function_single(.wait = 1), that should work as before. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
