X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5194ee82b4aafc35b32c96db11bdacea9bf548be;p=openwrt%2Fstaging%2Fblogic.git 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.
