fs/namespace::do_add_mount() says:

...
/* Refuse the same filesystem on the same mount point */
...

However, it is still possible to mount the same NFS filesystem to the
same mountpoitn several times:

mme@feivel:/.autofs/nfs/home/mme$ sudo mount zwerg:/exports/usr.local
/mnt
Password:
mme@feivel:/.autofs/nfs/home/mme$ sudo mount zwerg:/exports/usr.local
/mnt
mme@feivel:/.autofs/nfs/home/mme$ df|grep mnt
8570480 5685768 2449352 70% /mnt
8570480 5685768 2449352 70% /mnt

I'm not sure if this really is a bug as technically it does not create a
problem, but I know a lot of users who are pretty confused.

Michael
