      io_uring: batch reap of dead file registrations · 4a38aed2
      Jens Axboe authored
      We currently embed and queue a work item per fixed_file_ref_node that
      we update, but if the workload does a lot of these, then the associated
      kworker-events overhead can become quite noticeable.
      
      Since we rarely need to wait on these, batch them at 1 second intervals
      instead. If we do need to wait for them, we just flush the pending
      delayed work.
