> Currently INode#cleanSubtree is used to delete files/directories and collect
> corresponding blocks for future deletion. Its return value can be 0 even if
> file/dir has been deleted because we save snapshot copies. This breaks the
> original logic in FSDirectory#delete since FSDirectory#delete expects a
> positive value from a successful deletion.
