      net: remove 'fallback' argument from dev->ndo_select_queue() · a350ecce
      Paolo Abeni 提交于
      After the previous patch, all the callers of ndo_select_queue()
      provide as a 'fallback' argument netdev_pick_tx.
      The only exceptions are nested calls to ndo_select_queue(),
      which pass down the 'fallback' available in the current scope
      - still netdev_pick_tx.
      
      We can drop such argument and replace fallback() invocation with
      netdev_pick_tx(). This avoids an indirect call per xmit packet
      in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
      with device drivers implementing such ndo. It also clean the code
      a bit.
      
      Tested with ixgbe and CONFIG_FCOE=m
      
      With pktgen using queue xmit:

      mm: replace all open encodings for NUMA_NO_NODE · 98fa15f3
      Anshuman Khandual 提交于
      Patch series "Replace all open encodings for NUMA_NO_NODE", v3.
      
      All these places for replacement were found by running the following
      grep patterns on the entire kernel code.  Please let me know if this
      might have missed some instances.  This might also have replaced some
      false positives.  I will appreciate suggestions, inputs and review.
      
      1. git grep "nid == -1"
      2. git grep "node == -1"
      3. git grep "nid = -1"
      4. git grep "node = -1"
      
      This patch (of 2):
      
      At present there are multiple places where invalid node number is
      encoded as -1.  Even though implicitly understood it is always better to
      have macros in there.  Replace these open encodings for an invalid node
      number with the global macro NUMA_NO_NODE.  This helps remove NUMA
      related assumptions like 'invalid node' from various places redirecting
      them to a common definition.
