I am trying to understand your issue.

Do you mean you encountered a case in which there were two
dentries for the same directory entry (/path/to/fileA) but one had
a correct parent inode and the other had no parent inode.

Note that a dentry points to a parent dentry that points to the inode.
So are you claiming that the two dentries pointed to two different parent
dentries one of which had the correct inode the other null inode?
