You can't check if it's been handled, yes; but you can certainly check if you delivered it. I guess Javier wants to exclude the cases where userspace didn't have any chance to handle it. Javier: Do you have an idea how common the case "we broadcasted, but nobody listened so we got a timeout" is? If the usual reason for the timeout is that firmware was requested before a listener showed up, I'm not sure whether that check is worth it... - 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/
