[Yaffs] yaffs_InitialiseTags symbol undefined

Hi,
I'm trying to compile the yaffs2 cvs tree for a linux 2.6.9 kernel on an arm xscale proc.
I'm working with a big samsunng nand flash (256 MB, 2K page size).
Up to now I can compile the obj file yaffs.o using the Makefile that comes from the cvs but when I try to compile the kernel module (yaffs.ko) within the kernel source tree (make modules) I get an unresolved symbol:

*** Warning: "yaffs_InitialiseTags" [fs/yaffs2/yaffs.ko] undefined!

I tryed to grep the function in the yaffs2 dir. but I've only found a dectaration in yaffs_guts.h but no definition.

Am I doing something wrong?

thanks.
