      Pull md updates from Neil Brown:
      
       - an assortment of little fixes, several for minor races only likely to
         be hit during testing
      
       - further cluster-md-raid1 development, not ready for real use yet.
      
       - new RAID6 syndrome code for ARM NEON
      
       - fix a race where a write can return before failure of one device is
         properly recorded in metadata, so an immediate crash might result in
         that write being lost.

        md/raid5: ensure device failure recorded before write request returns.

      task_work: remove fifo ordering guarantee · c8219906
      Eric Dumazet authored
      In commit f341861f ("task_work: add a scheduling point in
      task_work_run()") I fixed a latency problem adding a cond_resched()
      call.
      
      Later, commit ac3d0da8 added yet another loop to reverse a list,
      bringing back the latency spike :
      
      I've seen in some cases this loop taking 275 ms, if for example a
      process with 2,000,000 files is killed.
      
      We could add yet another cond_resched() in the reverse loop, or we
      can simply remove the reversal, as I do not think anything
      would depend on order of task_work_add() submitted works.
      
      Fixes: ac3d0da8 ("task_work: Make task_work_add() lockless")
