Yeah, that hasn't been forgotten (nor have your comments about folding my special function into smp_call_function_single). The call function path is terribly unscalable at the moment on a lot of architectures, and also it isn't allowed to be used with interrupts off due to deadlock (which the queued version can allow, provided that wait=0). I will get around to sending that upstream soon. -- 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/
