      Freeing ->s_{inode,dentry}_lru in deactivate_locked_super() is wrong;
      the right place is destroy_super().  As it is, we leak them if sget()
      decides that new superblock it has allocated (and never shown to
      anybody) isn't needed and should be freed.

      pkt_sched: fq: rate limiting improvements · 0eab5eb7
      Eric Dumazet authored
      
      
      FQ rate limiting suffers from two problems, reported
      by Steinar :
      
      1) FQ enforces a delay when flow quantum is exhausted in order
      to reduce cpu overhead. But if packets are small, current
      delay computation is slightly wrong, and observed rates can
      be too high.
      
      Steinar had this problem because he disabled TSO and GSO,
      and default FQ quantum is 2*1514.
      
      (Of course, I wish recent TSO auto sizing changes will help
      to not having to disable TSO in the first place)
      
      2) maxrate was not used for forwarded flows (skbs not attached
      to a socket)
      
      Tested:
      
      tc qdisc add dev eth0 root est 1sec 4sec fq maxrate 8Mbit
      netperf -H lpq84 -l 1000 &

      ip6tnl: allow to use rtnl ops on fb tunnel · bb814094

      Now that it is done, we must remove the explicit call to

      in ip6_tnl_destroy_tunnels() when checking rtnl_link_ops of all netdevices (this

      ip_tunnel: Remove double unregister of the fallback device · cfe4a536
      Steffen Klassert authored
      When queueing the netdevices for removal, we queue the
      fallback device twice in ip_tunnel_destroy(). The first
      time when we queue all netdevices in the namespace and
      then again explicitly. Fix this by removing the explicit
      queueing of the fallback device.
      
      Bug was introduced when network namespace support was added
      with commit 6c742e71
      
       ("ipip: add x-netns support").
