[Yaffs] Is it a bug of yaffs_ResizeFile() ?

Hello all !

I use "dd of=/mnt/yaffs2/vfat.img bs=1024 seek=1800000 count=0" to
create a large file in yaffs2 quickly, but I found when I
umount/remount it , the filesize of vfat.img reduce to zero. I
searched the source of yaffs2 and I found it's the problem of
yaffs_ResizeFile() , so I wrote a simple patch. I don't know if the
patch is right , but anyway it worked well in my board.
