      NFSv4: Fix nfs4_init_uniform_client_string for net namespaces · 55b59293
      Trond Myklebust authored
      Commit 6f2ea7f2 (NFS: Add nfs4_unique_id boot parameter) introduces a
      boot parameter that allows client administrators to set a string
      identifier for use by the EXCHANGE_ID and SETCLIENTID arguments in order
      to make them more globally unique.
      
      Unfortunately, that uniquifier is no longer globally unique in the presence
      of net namespaces, since each container expects to be able to set up their
      own lease when mounting a new NFSv4/4.1 partition.
      The fix is to add back in the container-specific hostname in addition to
      the unique id.

      NFS: Fix return type of nfs4_end_drain_session() stub · b14b7979
      Chuck Lever authored
      Clean up: when NFSv4.1 support is compiled out,
      nfs4_end_drain_session() becomes a stub.  Make the synopsis of the
      stub match the synopsis of the real version of the function.

      NFSv4: encode_attrs should not backfill the bitmap and attribute length · d7067b2d
      Trond Myklebust authored
      The attribute length is already calculated in advance. There is no
      reason why we cannot calculate the bitmap in advance too so that
      we don't have to play pointer games.

      Pull thermal management fixes from Zhang Rui:
       "These are fixes collected over the last week, they fixes several
        problems caused by the x86_pkg_temp_thermal introduced in 3.11-rc1.
      
        Specifics:
      
         - the x86_pkg_temp_thermal driver causes crash on systems with no
           package MSR support as there is a bug in the logic to check
           presence of DTHERM and PTS feature together.  Added a change so
           that when there is no PTS support, module doesn't get loaded.
      
         - fix krealloc() misuse in pkg_temp_thermal_device_add().
      
           If krealloc() returns NULL, it doesn't free the original.  Thus if
           we want to exit because of the krealloc() failure, we must make
           sure the original one is freed.
      
         - The error code path of the x86 package temperature thermal driver's
           initialization routine makes an unbalanced call to
           get_online_cpus(), which causes subsequent CPU offline operations,
           and consequently system suspend, to permanently block in
           cpu_hotplug_begin() on systems where get_core_online() returns an
           error code.
      
           Remove the extra get_online_cpus() to fix the problem"

      Thermal: Fix lockup of cpu_down() · ace120dc
      Steven Rostedt authored
      Commit f1a18a10 "Thermal: CPU Package temperature thermal" had code
      that did a get_online_cpus(), run a loop and then do a
      put_online_cpus(). The problem is that the loop had an error exit that
      would skip the put_online_cpus() part.
      
      In the error exit part of the function, it also did a get_online_cpus(),
      run a loop and then put_online_cpus(). The only way to get to the error
      exit part is with get_online_cpus() already performed. If this error
      condition is hit, the system will be prevented from taking CPUs offline.
      The process taking the CPU offline will lock up hard.
      
      Removing the get_online_cpus() removes the lockup as the hotplug CPU
      refcount is back to zero.
      
      This was bisected with ktest.
