+ Wide tnodes are only used for large NAND arrays (>=32MB for
+ 512-byte page devices and >=128MB for 2k page devices). They use
+ slightly more RAM but are faster since they eliminate chunk group
+ searching.
+
+ Setting this to 'y' will force tnode width to 16 bits and make
+ large arrays slower.
+
+ If unsure, say N.
