From c947f7e1e31a708f5a4ea8c1a627bec578cd9223 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Fri, 22 May 2015 17:43:54 +0200 Subject: mac802154: remove mib lock This patch removes the mib lock. The new locking mechanism is to protect the mib values with the rtnl lock. Note that this isn't always necessary if we have an interface up the most mib values are readonly (e.g. address settings). With this behaviour we can remove locking in hotpath like frame parsing completely. It depends on context if we need to hold the rtnl lock or not, this makes the callbacks of ieee802154_mlme_ops unnecessary because these callbacks hols always the locks.
