Johannes Berg 43ba7e958f mac80211: atomically check whether STA exists already ... When a STA structure is added, it is often checked whether it already exists before adding it. This, however, isn't done atomically so there is a race condition that could lead to two STA structures being added with the same MAC address. This patch changes sta_info_add() to return an ERR_PTR in case of failure and adds the failure mode -EEXIST when the STA already exists.
