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. 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. -- Dave Chinner david@fromorbit.com
