         need to move security_d_instantiate(); once that becomes safe, the
         rest will be a matter of rather short series local to fs/*.c

       "A small set of patches for audit this time; just three in total and
        one is a spelling fix.
      
        The two patches with actual content are designed to help prevent new
        instances of auditd from displacing an existing, functioning auditd
        and to generate a log of the attempt.  Not to worry, dead/stuck auditd
        instances can still be replaced by a new instance without problem.
      
        Nothing controversial, and everything passes our regression suite"

         3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
      
         4) Allow the use of SO_REUSEPORT in order to do per-thread processing
         of incoming TCP/UDP connections.  The muxing can be done using a
         BPF program which hashes the incoming packet.  From Craig Gallek.
      
         5) Add a multiplexer for TCP streams, to provide a messaged based
            interface.  BPF programs can be used to determine the message
            boundaries.  From Tom Herbert.
      
         6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
      
         7) Avoid factorial complexity when taking down an inetdev interface
            with lots of configured addresses.  We were doing things like
            traversing the entire address less for each address removed, and
            flushing the entire netfilter conntrack table for every address as
            well.
      
         8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
      
         9) Allow offloading u32 classifiers to hardware, and implement for
            ixgbe, from John Fastabend.
      
        10) Allow configuring IRQ coalescing parameters on a per-queue basis,
            from Kan Liang.
      
        11) Extend ethtool so that larger link mode masks can be supported.
            From David Decotigny.
      
        12) Introduce devlink, which can be used to configure port link types
            (ethernet vs Infiniband, etc.), port splitting, and switch device
            level attributes as a whole.  From Jiri Pirko.
      
        13) Hardware offload support for flower classifiers, from Amir Vadai.
      
        14) Add "Local Checksum Offload".  Basically, for a tunneled packet
            the checksum of the outer header is 'constant' (because with the
            checksum field filled into the inner protocol header, the payload
            of the outer frame checksums to 'zero'), and we can take advantage
            of that in various ways.  From Edward Cree"

      Pull cgroup updates from Tejun Heo:
       "cgroup changes for v4.6-rc1.  No userland visible behavior changes in
        this pull request.  I'll send out a separate pull request for the
        addition of cgroup namespace support.
      
         - The biggest change is the revamping of cgroup core task migration
           and controller handling logic.  There are quite a few places where
           controllers and tasks are manipulated.  Previously, many of those
           places implemented custom operations for each specific use case
           assuming specific starting conditions.  While this worked, it makes
           the code fragile and difficult to follow.
      
           The bulk of this pull request restructures these operations so that
           most related operations are performed through common helpers which
           implement recursive (subtrees are always processed consistently)
           and idempotent (they make cgroup hierarchy converge to the target
           state rather than performing operations assuming specific starting
           conditions).  This makes the code a lot easier to understand,
           verify and extend.
      
         - Implicit controller support is added.  This is primarily for using
           perf_event on the v2 hierarchy so that perf can match cgroup v2
           path without requiring the user to do anything special.  The kernel
           portion of perf_event changes is acked but userland changes are
           still pending review.
      
         - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
           certain environments.
      
         - There is a regression introduced during v4.4 devel cycle where
           attempts to migrate zombie tasks can mess up internal object
           management.  This was fixed earlier this week and included in this
           pull request w/ stable cc'd.
      
         - Misc non-critical fixes and improvements"

      bonding: fix bond_get_stats() · fe30937b
      Eric Dumazet authored
      bond_get_stats() can be called from rtnetlink (with RTNL held)
      or from /proc/net/dev seq handler (with RCU held)
      
      The logic added in commit 5f0c5f73 ("bonding: make global bonding
      stats more reliable") kind of assumed only one cpu could run there.
      
      If multiple threads are reading /proc/net/dev, stats can be really
      messed up after a while.
      
      A second problem is that some fields are 32bit, so we need to properly
      handle the wrap around problem.
      
      Given that RTNL is not always held, we need to use
      bond_for_each_slave_rcu().
      
      Fixes: 5f0c5f73 ("bonding: make global bonding stats more reliable")
