-/* This file contains the code for the internal structure of the
-   Journaling Flash File System, JFFS.  */
-
-/*
- * Todo list:
- *
- * memcpy_to_flash() and memcpy_from_flash() functions.
- *
- * Implementation of hard links.
- *
- * Organize the source code in a better way. Against the VFS we could
- * have jffs_ext.c, and against the block device jffs_int.c.
- * A better file-internal organization too.
- *
- * A better checksum algorithm.
- *
- * Consider endianness stuff. ntohl() etc.
- *
- * Are we handling the atime, mtime, ctime members of the inode right?
- *
- * Remove some duplicated code. Take a look at jffs_write_node() and
- * jffs_rewrite_data() for instance.
- *
- * Implement more meaning of the nlink member in various data structures.
- * nlink could be used in conjunction with hard links for instance.
- *
- * Better memory management. Allocate data structures in larger chunks
- * if possible.
- *
- * If too much meta data is stored, a garbage collect should be issued.
- * We have experienced problems with too much meta data with for instance
- * log files.
- *
- * Improve the calls to jffs_ioctl(). We would like to retrieve more
- * information to be able to debug (or to supervise) JFFS during run-time.

-   with zeroes so that the scan of the flash will work smoothly next
-   time.  (The data in the file could for instance be a JFFS image
-   which could cause enormous confusion during a scan of the flash
-   device if we didn't do this.)
-     There are two phases in this procedure: First, the clearing of
-   the name and data parts of the node. Second, possibly also clearing
-   a part of the raw inode as well.  If the box is power cycled during
-   the first phase, only the checksum of this node-to-be-cleared-at-
-   the-end will be wrong.  If the box is power cycled during, or after,
-   the clearing of the raw inode, the information like the length of
-   the name and data parts are zeroed.  The next time the box is
-   powered up, the scanning algorithm manages this faulty data too
-   because:
-
-   - The checksum is invalid and thus the raw inode must be discarded
-     in any case.
-   - If the lengths of the data part or the name part are zeroed, the
-     scanning just continues after the raw inode.  But after the inode
-     the scanning procedure just finds zeroes which is the same as
-     dirt.
-
-   So, in the end, this could never fail. :-)  Even if it does fail,
-   the scanning algorithm should manage that too.  */
