Description of problem:
Make sure that automount "symlinks" are followed regardless of LOOKUP_FOLLOW; it should have no effect on them.

For this vulnerability to work, you need the support for O_NOFOLLOW (predates 2.6.12), openat (2.6.16 onwards) and use by NFS of 'trapdoor mounts' (2.6.18 onwards).
