Description

This Jira will replace the existing ArrayList with DirectoryDiffList to store directory diffs for snapshots based on the config value of maxSkipLevels. If the config specified is set to greater than 0, SnapshotSkipList will be used to store DirectoryDiffs else ArrayList will be used. The config value is set to 0 by default.
