Actually, things aren't as simple as they seem. Without the patch applied:
[root@andromeda ~]# ls -l /proc/fs/afs/cells
-r--r--r--. 1 root root 0 Jan 31 00:04 /proc/fs/afs/cells
[root@andromeda ~]# echo add your-file-system.com 204.29.154.37
>/proc/fs/afs/cells
[root@andromeda ~]#
You'll observe there is no error reported on the echo command.
Further, looking in dmesg, I see:
kAFS: Added new cell 'your-file-system.com'
So the file *is* writable, *despite* i_mode.
