+config OVERLAY_FS_REDIRECT_DIR
+        bool "Overlayfs: turn on redirect dir feature by default"
+        depends on OVERLAY_FS
+        help
+          If this config option is enabled then overlay filesystems will use
+          redirects when renaming directories by default.  In this case it is
+          still possible to turn off redirects globally with the
+          "redirect_dir=off" module option or on a filesystem instance basis
+          with the "redirect_dir=off" mount option.
+
+          Note, that redirects are not backward compatible.  That is, mounting
+          an overlay which has redirects on a kernel that doesn't support this
+          feature will have unexpected results.
