I guess i see why we did not understand each other: these are calls to ieee80211_stop_queues, not directly to ieee80211_stop_queue (even though stop_queues ultimately calls stop_queue). The difference is relevant because, if some kind of locking (for example) was needed in the special contexts stop_queues only might be called from, these locks would be held inside stop_queues, around its stop_queue calls. :) Is there any way to tell mac80211 the device is in a [temporary] "non-functional" state (reset, association loss...) ? - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
