> Currently after a rename operation within/from a snapshottable directory, a
> reference node is created in both src and dst subtree, pointing to the
> original renamed inode. With this change the original quota computation may
> count the quota usage of the renamed subtree multiple times. This jira tries
> to fix this issue.
