While at it, could you also delete the incorrect comment? I don't know
how the above part is relevant
with failfast after the refactor.
/*
* When the device is faulty, it is not
necessary to
* handle write error.
- * For failfast, this is the only remaining device,
- * We need to retry the write without FailFast.
*/
Thanks,
