iirc we ended up deciding that the futex problems around that time were due to userspace problems (a version of libc). But then, there's no discussion around Seto's patch and it didn't get applied. So I don't know what happened to that work - it's all a bit mysterious. Is this a 100% repeatable hang, or is it some occasional race? - 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/
