You should have put that in the patch description.

Now I understand why there's been a sudden surge of irrelevant one
line changes from random people that have never touched XFS before.

<sigh>

Ok, lets churn the code just to shut the stupid checker up. This
doesn't fix a bug, it doesn't change behaviour, it just makes
coverity happy. Convert it to the for loop plus ASSERT I mentioned
in a previous message.

Cheers,

Dave.
