Hello,

I have arm board with a Toshiba 128MB NAND flash which
is 528bytes/page. 
I downloaded the newest yaffs code and patch it to
linux kernel 2.6.11.10. I select yafss and mtd support
from muneconfig. After make, I got the error messages
at the end:

  CHK     include/linux/version.h

date.

yaffs_mtdif does compile which include the 4 undefined
functions.  But why does it complain about the 4
functions.
