Guys, can you explain what is the need for such a change in the first place?
Another round of confusion? Forcing everybody to upgrade their painfully
crafted kernels (your CVS version won't apply to e.g. 2.6.12 kernel that was
the last one before rather major change in ARM architecture, will it?)?
Why don't just fix YAFFS2 itself to make it work with a stock kernel? It's
easy to do and the appropriate patch is out for quite a long time, tested
and works for everyone. Patch for YAFFS2 it is, not for kernel.
