[Yaffs] Filepermissions in Yaffs2

Hi,

It seems yaffs2 is not honoring file permissions. Below always works

# touch file
# ls -l file
-rw-r--r-- file
# chmod u-w x
# ls -l file
-r--r--r-- file
# echo 1 > file
# cat file
1
# echo2 > file
# cat file
2

Is there a way to set readonly permission on files ?
