      tcp: Fix tcp_hybla zero congestion window growth with small rho and large cwnd. · 9d2c27e1
      Daniele Lacamera authored
      Because of rounding, in certain conditions, i.e. when in congestion
      avoidance state rho is smaller than 1/128 of the current cwnd, TCP
      Hybla congestion control starves and the cwnd is kept constant
      forever.
      
      This patch forces an increment by one segment after #send_cwnd calls
      without increments(newreno behavior).

      net: Fix netdev_run_todo dead-lock · 58ec3b4d
      Herbert Xu authored
      Benjamin Thery tracked down a bug that explains many instances
      of the error
      
      unregister_netdevice: waiting for %s to become free. Usage count = %d
      
      It turns out that netdev_run_todo can dead-lock with itself if
      a second instance of it is run in a thread that will then free
      a reference to the device waited on by the first instance.
      
      The problem is really quite silly.  We were trying to create
      parallelism where none was required.  As netdev_run_todo always
      follows a RTNL section, and that todo tasks can only be added
      with the RTNL held, by definition you should only need to wait
      for the very ones that you've added and be done with it.
      
      There is no need for a second mutex or spinlock.
      
      This is exactly what the following patch does.
