Question about vfsmount test in __do_follow_link

[Ian Kent <raven@themaw.net>]

In __do_follow_link I see

if (path->mnt == nd->mnt)
	mntget(path->mnt);

immediately before

cookie = dentry->d_inode->i_op->follow_link(dentry, nd);

I can't see the case where the vfsmount is ever different. This would have 
to mean a mount was followed but this shouldn't be possible for a 
symlink?

Can someone enlighten me?

Ian
