As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.
