> {{FSDirectory.getListingInt}} does a byte/string conversion for the byte[]
> startAfter just to determine if it should be resolved as an inode path. This
> is not the common case but rather for NFS support so it should be avoided.
> When the resolution is necessary the conversions may be reduced.
