From 5c0c36412b2dc6b1e243c7e9115306fe286583b7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 12 May 2011 14:31:49 +0200 Subject: mac80211: make key locking clearer The code in ieee80211_del_key() doesn't acquire the key_mtx properly when it dereferences the keys. It turns out that isn't actually necessary since the key_mtx itself seems to be redundant since all key manipulations are done under the RTNL, but as long as we have the key_mtx we should use it the right way too.
