      iov_iter: Add I/O discard iterator · 9ea9ce04
      David Howells authored
      Add a new iterator, ITER_DISCARD, that can only be used in READ mode and
      just discards any data copied to it.
      
      This is useful in a network filesystem for discarding any unwanted data
      sent by a server.

      iov_iter: Separate type from direction and use accessor functions · aa563d7b
      David Howells authored
      In the iov_iter struct, separate the iterator type from the iterator
      direction and use accessor functions to access them in most places.
      
      Convert a bunch of places to use switch-statements to access them rather
      then chains of bitwise-AND statements.  This makes it easier to add further
      iterator types.  Also, this can be more efficient as to implement a switch
      of small contiguous integers, the compiler can use ~50% fewer compare
      instructions than it has to use bitwise-and instructions.
      
      Further, cease passing the iterator type into the iterator setup function.
      The iterator function can set that itself.  Only the direction is required.

      iov_iter: Use accessor function · 00e23707
      David Howells authored
      Use accessor functions to access an iterator's type and direction.  This
      allows for the possibility of using some other method of determining the
      type of iterator than if-chains with bitwise-AND conditions.

      amd-gpu: Don't undefine READ and WRITE · 1fcb748d
      David Howells authored
      Remove the undefinition of READ and WRITE because these constants may be
      used elsewhere in subsequently included header files, thus breaking them.
      
      These constants don't actually appear to be used in the driver, so the
      undefinition seems pointless.

      David S. Miller authored
      net/sched/cls_api.c has overlapping changes to a call to
      nlmsg_parse(), one (from 'net') added rtm_tca_policy instead of NULL
      to the 5th argument, and another (from 'net-next') added cb->extack
      instead of NULL to the 6th argument.
      
      net/ipv4/ipmr_base.c is a case of a bug fix in 'net' being done to
      code which moved (to mr_table_dump)) in 'net-next'.  Thanks to David
      Ahern for the heads up.

      This series provides misc updates to mlx5 core and netdevice driver.
      
      1) From Tariq Toukan: Refactor fragmented buffer struct fields and init flow.
      
      2) From Vlad Buslov, Flow counters cache improvements and fixes follow up.
      as a follow up work for the previous series of the mlx5 flow counters,
      Vlad provides two fixes:
        2.1) Take fs_counters dellist before addlist
      Fixes: 6e5e2283 ("net/mlx5: Add new list to store deleted flow counters")
        2.2) Remove counter from idr after removing it from list
      Fixes: 12d6066c ("net/mlx5: Add flow counters idr")
      
      From Shay Agroskin,
      3) Add FEC set/get FW commands and FEC ethtool callbacks support
      4) Add new ethtool statistics to cover errors on rx, such as FEC errors.
