   1 [PATCH] mac80211: hoist sta->lock from reorder release timer
   2
   3 The patch "mac80211: AMPDU rx reorder timeout timer" clashes
   4 with "mac80211: use netif_receive_skb in ieee80211_rx callpath"
   5
   6 The timer itself is part of the station's private struct and
   7 it gets killed whenever the station is removed. Therefore
   8 the extra sta->lock protection (that can interferes with the
   9 tx path) is not necessary.
