After the probe run finishes, the context will still exist until the deferred io_uring teardown. When running iou-zcrx the second time, io_uring_register_ifq() can return -EEXIST due to the existence of the old context. The fix is simple: wait for the context teardown using the new mp_clear_wait() utility before running the second instance of iou-zcrx.
