JFFS2 for 2.0 kernel?
Hello!
As I understand JFFS2 is not publically available for the 2.0-kernel. Can anyone give some opinions of how much work a backport (from 2.4 to 2.0) effort would be?
Any pointers of where the big problems are?
Is it even possible?
Best regards,

It would be quite a lot of work; the file system layer in Linux changed dramatically between the 2.0 and 2.2 kernels. You'd have a better chance of porting to 2.2 -- in fact I think someone's already done so.
Why do you want 2.0?

I was afraid of that, but we need the 2.0 kernel (at least for now).

We are using using JFFS with MTD and the uClinux 2.0.38 kernel. I have some concerns re. JFFS and powercycling and as I understand the JFFS2 is more robust. Another option would be to make JFFS more robust but I assume that that might be an even bigger challenge.

True. JFFS2 _is_ the result of making JFFS more robust. :)
What chance of using 2.4 uClinux?
