      Pull io_uring fixes from Jens Axboe:
       "A bit of a mix between fallout from the worker change, cleanups and
        reductions now possible from that change, and fixes in general. In
        detail:
      
         - Fully serialize manager and worker creation, fixing races due to
           that.
      
         - Clean up some naming that had gone stale.
      
         - SQPOLL fixes.
      
         - Fix race condition around task_work rework that went into this
           merge window.
      
         - Implement unshare. Used for when the original task does unshare(2)
           or setuid/seteuid and friends, drops the original workers and forks
           new ones.
      
         - Drop the only remaining piece of state shuffling we had left, which
           was cred. Move it into issue instead, and we can drop all of that
           code too.
      
         - Kill f_op->flush() usage. That was such a nasty hack that we had
           out of necessity, we no longer need it.
      
         - Following from ->flush() removal, we can also drop various bits of
           ctx state related to SQPOLL and cancelations.
      
         - Fix an issue with IOPOLL retry, which originally was fallout from a
           filemap change (removing iov_iter_revert()), but uncovered an issue
           with iovec re-import too late.
      
         - Fix an issue with system suspend.
      
         - Use xchg() for fallback work, instead of cmpxchg().
      
         - Properly destroy io-wq on exec.
      
         - Add create_io_thread() core helper, and use that in io-wq and
           io_uring. This allows us to remove various silly completion events
           related to thread setup.
      
         - A few error handling fixes.
      
        This should be the grunt of fixes necessary for the new workers, next
        week should be quieter. We've got a pending series from Pavel on
        cancelations, and how tasks and rings are indexed. Outside of that,
        should just be minor fixes. Even with these fixes, we're still killing
        a net ~80 lines"

      RDMA/rxe: Fix errant WARN_ONCE in rxe_completer() · 545c4ab4
      Bob Pearson authored
      In rxe_comp.c in rxe_completer() the function free_pkt() did not clear skb
      which triggered a warning at 'done:' and could possibly at 'exit:'. The
