If any unused fields got used, they had to be added to the exception list. Such changes caused too many false alarms. So, I have changed the comparison algorithm to compare a selected set of fields that are not expected to change. This new algorithm causes far fewer false hits and still does a good job of detecting problems when they have really occurred. In particular, this change should ease the transition to kernels supporting UFS2 which make some significant changes to the superblock. Sponsored by: DARPA, NAI Labs |
