> Currently rename entries are never reclaimed and these entries can be
> reclaimed on snapshot deep cleaning by just peeking into the previous
> snapshot if the object exists either in the
> directoryTable/FileTable/KeyTable. While performing this operation we should
> ensure read locks are taken on the previous snapshot and the previous
> snapshot is not deleted. As part of this patch we implement
> ReclaimableRenameEntryFilter which extends abstract class ReclaimableFilter
> and check whether this rename entry corresponding to the object exists in the
> previous snapshot.
