      IPVS: Use global mutex in ip_vs_app.c · 736561a0
      Simon Horman authored
      
      
      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.
