From 5194ee82b4aafc35b32c96db11bdacea9bf548be Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 7 May 2008 19:44:20 +0400 Subject: [PATCH] mac80211: Fix one more call to synchronize_rcu in atomic context. (This set applies OK without the previous one of 4 patches, but with some fuzz in the 7th one) The mesh_path_node_free() does so under hashwlock. But, this one is called 1. from mesh_path_add() after an old hash is hidden and synchronize_rcu() is calld 2. mesh_pathtbl_unregister(), when the module is being unloaded and no devices exist to mess with this hash. So, it seems to me, that simply removing the call is OK. Signed-off-by: Pavel Emelyanov Signed-off-by: John W.
