Darrick J. Wong 77ede5f44b xfs: walk directory parent pointers to determine backref count
If the filesystem has parent pointers enabled, walk the parent pointers
of subdirectories to determine the true backref count.  In theory each
subdir should have a single parent reachable via dotdot, but in the case
of (corrupt) subdirs with multiple parents, we need to keep the link
counts high enough that the directory loop detector will be able to
correct the multiple parents problems.
