Bug#694624: /usr/sbin/xfs_freeze: freezes under lying (root)

OK, can you then fix the man page to describe the real behaviour of the
program so that users have a chance to intelligently decide what error
checking to do in their scripts.
I.E the argument isn't a mount point, it's a path, and perhaps use
'filesystem' rather than 'xfs' consistently.

It may also be a good idea to point out in the man page that you should be
extremely careful running this if you are not logged in interactively, 
even a
disconnected ssh session will prevent you running xfs_freeze -u to manually
unfreeze the root filesystem.
