Hi Johannes, We have observed memory leaks because of ampdu tx pending queue not being freed before destroying the station info. In '__sta_info_destroy' when we attempt the destroy the ampdu sessions in 'ieee80211_sta_tear_down_BA_sessions', the driver calls 'ieee80211_stop_tx_ba_cb_irqsafe' to delete the ampdu structures (tid_tx) and splice the pending queues and this job gets queued in sdata workqueue. However, the sta entry can get destroyed before the above work gets scheduled and hence the race. Purging the queues and freeing the tid_tx would avoid the leak, but I wanted to get your thoughts before attempting to fix this cleanly.
