I am trying to establish a re-port of yaffs2 to 2.4.25-vrs2-tcl1 using 
2k nand and have come across an unexpected issue.

The port is the current cvs with several modifications.

- #define __user is needed in yaffs_fs.c for 2.4 kernels

- An update to yaffs_mtdif2.c to extract the tags according to the 
current oobinfo for raw oob reads as per Wookeys recent efforts.

- A patch to mtdpart.c to copy the master mtd oobinfo to a slave mtd as 
per later 2.6 kernels without which the slave oobinfo is empty and 
causes grief when mounting a yaffs2 partition. This may be the first 
report of this for the 2.4.25-vrs2-tcl1 kernel.

I compile the kernel with either a Dec 2005 or the latest cvs. The older 
one fails to boot corrctly due to oob alignment but is otherwise ok. The 
new version however seems to corrupt devfs so that when mounting devfs 
(just after yaffs2 is successfully mounted as root) error -2 is returned 
from mount_devfs_fs(). This is *new* behaviour as far as I can see.

Removing the third patch makes no difference.

Has anyone a similar experience?
