- "Lazy loading" defers loading file details until they are
- required. This saves mount time, but makes the first look-up
- a bit longer.
-
- Lazy loading will only happen if enabled by this option being 'n'
- and if the appropriate tags are available, else yaffs2 will
- automatically fall back to immediate loading and do the right
- thing.
-
- Lazy laoding will be required by checkpointing.
-
- Setting this to 'y' will disable lazy loading.
+ This defaults Yaffs to using its own ECC calculations on tags instead of
+ just relying on the MTD.
+ This behavior can also be overridden with tags_ecc_on and
+ tags_ecc_off mount options.
