Description

The InodeDiffList class contains a generic List to store snapshotDiffs. The generic List interface is bulky and to store and manage snapshotDiffs, we need only a few specific methods. 

This Jira proposes to define a new interface called DiffList interface which will be used to store and manage snapshotDiffs.
