Here is NandFS, a NAND Flash Filesystem.
NandFS is similar to YAFFS2 (in some ways), but the codebase is much more
cleaner and simpler. And we'll try to go mainline.
Development started at Adeneo (http://www.adeneo-embedded.com/srt/en/home) in
2007. After a long pause, I re-started to clean the code in october 2008.
With the new UBIFS, we might think than there is no room for another flash
filesystem. But another GPLed filesystem can't hurt anyone. Some of us may
have heard some words about UFFS, but this project is in no way related to
*IMPORTANT*: NandFS is under active development, and can't be considered safe
or stable !
NandFS aims to be:
- Write-Optimized (write-back + internal caches)
- writeback and "budgeting"
NandFS short term todo:
- (A lot of) Test
- Better locking (no more "Big NandFS Lock")
- checkpoint/summary support
- ram usage optimizations
- xattr support
- acl support
The code can be found at http://git.iksaif.net/
I'm currently working on kernel-doc, but the more important is done.
There is no whitepaper to explain how it works right now, but nandfs.h and
scan.c explains a lot and they are well commented.
It's all Licenced under GPLv2.
Please post your question/comments/bugs/patches.
