> NFS readdir and readdirplus operations return a null directory attribute on some failure
paths. This causes clients to get a 'Stale file handle' error which can only be fixed by unmounting
and remounting the share.
> The issue can be reproduced by running 'ls' against a large directory which is being
actively modified, triggering the 'cookie mismatch' failure path.
> {code}
>         } else {
>           LOG.error("cookieverf mismatch. request cookieverf: " + cookieVerf
>               + " dir cookieverf: " + dirStatus.getModificationTime());
>           return new READDIRPLUS3Response(Nfs3Status.NFS3ERR_BAD_COOKIE);
>         }
> {code}
> Thanks to [~brandonli] for catching the issue.
