Porting JFFS II to 2.4.6

Porting JFFS II to 2.4.6

[Steve_Chen]

Hi all,
I like to get some expert advice.  We have frozen our development platform
at kernel version 2.4.6 for months now.   And we like to port the latest
JFFS II source code from 2.4.16 to 2.4.6.

I noticed that there are some structure changes in fs directory from 2.4.6
to 2.4.16.  What is the most effective way to do the porting ?

1) Do we just port the JFFS II code from 2.4.16 to 2.4.6 ??
2) Do we port the whole fs directory source tree from 2.4.16 to 2.4.6 ??
3) Is there a better way to port ??
4) What are the areas we should watch out ??

Thanks.

Yup, do that and see, what all breaks. Then fix those parts and you
did it.
The best way would be to create a patch from 2.4.6 to 2.4.16 for the
jffs2 stuff exclusively, read it and see, what might/will break. You
might want to upgrade the mtd code as well, for obvious reasons.
