From 661eb3811df568161399af0048f1ecb4ac073687 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 12 Jun 2013 22:47:56 +0200 Subject: [PATCH] mac80211: fix TX aggregation TID struct leak Ben reports that kmemleak is saying TX aggregation TID structs are leaked. Given his workload, I suspect that they're leaked because stations are destroyed before their aggregation sessions get a chance to start. Fix this by simply freeing structs that are not used yet.
