best nand flash fs for 2.0.38 kernel?

[luoxiao]

Hi, all

I'm currently trying to add nand flash file system support for the linux 
2.0.38 porting on my company's product. I choosed the JFFS but the JFFS2 
because it fits the old 2.0.x kernel. In the processing of porting I met a 
lot of troubles and I thought some of them are caused by bugs of JFFS code 
rather by my porting. So a question is: is the JFFS stable enough for product 
usage? I saw it is still in the fs/ directory of the brand-new 2.6.0 kernel. 
Does this fact mean that the version of JFFS in the 2.6.0 kernel is stable 
enough to use? I've searched the docs and mail archive but it seems that no 
one is using JFFS now. So the question is: what is the best nand flash file 
system for the 2.0.x kernel? 

Any hints are appreciated, thanks!

AFAIK JFFS does not support NAND, but JFFS2 does, so does YAFFS.

"Best" is hard to define and mileage will vary. Both YAFFS and JFFS2 have 
there place in the world.

I can't speak for porting JFFS2, but I can for YAFFS.

YAFFS currently works with 2.4 and 2.6. YAFFS does not use many kernel 
features (threads etc), so I would expect porting to other Linux variants to 
be not too bad.
