io_uring: batch reap of dead file registrations 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. Signed-off-by: Jens Axboe <axboe@kernel.dk>
