       "Just a few cleanups for 4.3 merge window for the 9p file system.  I've
        gotten several more over the past week, but this group has been in
        for-next for at least a couple of weeks so I figured I'd push them
        first while I test the rest.
      
        Most of the ones not in this set are bug-fixes anyways so I could hold
        them for rc1"

      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")
