From d29cecda036f251aee4947f47eea0fe9ed8cc931 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 4 Dec 2009 14:25:43 -0800 Subject: mac80211: fix reorder buffer release My patch "mac80211: correctly place aMPDU RX reorder code" uses an skb queue for MPDUs that were released from the buffer. I intentially didn't initialise and use the skb queue's spinlock, but in this place forgot that the code variant that doesn't touch the spinlock is needed. Thanks to Christian Lamparter for quickly spotting the bug in the backtrace Reinette reported.
