[PATCH] kjournald keeps reference to namespace

In daemonize() a new thread gets cleaned up and 'merged' with init_task.
The current fs_struct is handled there, but not the current namespace.

This adds the namespace part.

[ Eric Biederman pointed out the namespace wrappers, and also notes that
  we can't ever count on using our parents namespace because we already
  have called exit_fs(), which is the only way to the namespace from a
  process. ]
