This patch series contains a few loosely related changes in mac80211 I did over the past few days: * clarify use of TX status/RX callbacks as per my previous mail, the irqsafe/non-irq-safe stuff * safely free beacon in ieee80211_if_reinit This is necessary for reentrancy reasons with ieee80211_beacon_get() * split ieee80211_key_alloc Preparation for RCU-ifying STA info, split key allocation into allocation and insertion * RCU-ify STA info structure access Remove STA refcount and instead protect them by RCU * split ieee80211_txrx_data Mostly unrelated, split up txrx_data and flags into one struct for TX and one for RX * split sta_info_add Split sta_info_add into _alloc and _link to resolve a few races and allow GFP_KERNEL allocations in many cases (which was removed by the RCU-ification patch) * remove STA info's last_ack stuff Remove some unused stats members * clean up sta_info and document locking Document and clean up the definition of struct sta_info and document the locking (deficiencies) I'd like to have somebody else look over these but I'm confident that the changes do not, at least, introduce regressions. johannes
