-config YAFFS_DISABLE_WIDE_TNODES
- bool "Turn off wide tnodes"
- depends on YAFFS_FS
- default n
- help
- Wide tnodes are only used for 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 save
- memory but make large arrays slower.
