The reason not checking errno is that `chattr +i` is a very basic operation,<br>
if it fails, most probably it's not supported. NFS returning ENOTTY<br>
makes checking errno more tricky. So I did not check it and made it as<br>
simple as the checking in xfstests.<br>
<br>
Thanks very much for reviewing!<br>
