+    archive/tar: don't treat multiple file system links as a tar hardlink
+    
+    Do not assume that if stat shows multiple links that we should mark the
+    file as a hardlink in the tar format.  If the hardlink link was not
+    referenced, this caused a link to "/".  On an overlay file system, all
+    files have multiple links.
+    
+    The caller must keep the inode references and set TypeLink, Size = 0,
+    and LinkName themselves.
