      This change isn't really necessary for correctness, but it prevents lockdep
      from getting upset and then disabling itself.

      Add parameter to add_partial to avoid having two functions · 7c2e132c
      Christoph Lameter 提交于
      Add a parameter to add_partial instead of having separate functions.  The
      parameter allows a more detailed control of where the slab pages is placed in
      the partial queues.
      
      If we put slabs back to the front then they are likely immediately used for
      allocations.  If they are put at the end then we can maximize the time that
      the partial slabs spent without being subject to allocations.
      
      When deactivating slab we can put the slabs that had remote objects freed (we
      can see that because objects were put on the freelist that requires locks) to
      them at the end of the list so that the cachelines of remote processors can
      cool down.  Slabs that had objects from the local cpu freed to them (objects
      exist in the lockless freelist) are put in the front of the list to be reused
      ASAP in order to exploit the cache hot state of the local cpu.
      
      Patch seems to slightly improve tbench speed (1-2%).
