Description

The method replaces an existing child with a new child. However, it does not take care the case the child also an INodeDirectory. In such case, the parent pointers of the children of the child have to be updated to the new child.

Only FSDirectory.unprotectedSetQuota(..) calls this method so that the child is always an INodeDirectory.
