Sorry... you're correct. That should have been "ls -F" or "ls --color", both
of which are, I believe, commonly used - _they_ definitely use stat() as well
as lstat().

You're right about follow_link() not recursing... it would have to recurse
itself, and so can avoid that. However, if it only ever follows to itself, how
does that help? That never actually gets you anywhere... It needs to trigger a
mount at some point.
Or do you mean it should follow to an arbitrary (disconnected, otherwise it
changes the topology from what the AFS admin required) dentry with a dummy
directory inode attached to it?
