I just built against the linux 2.6.32 kernel and had no problems.

Does it look like you're using the single or multi-version variant of
yaffs_vfs.c? You need to be using the multi-version variant since you are not
compiling against the latest kernel (2.6.36).

The single-version variant is kept current with Linus' 2.6 git and will not
compile against older kernelss.

The yaffs patch-ker.sh script changed. How did you call it?

Try doing this:

1. get latest yaffs2 git
2. cd yaffs2-dir
3. rm -rf kernel-dir/fs/yaffs2
4. ./patch-ker.sh l m kernel-dir
