Saied Kazemi 490ca71866 Fix AUFS pathname handling when branch is not exposed 
The code that fixes up AUFS pathnames associated with vma entries (see
commit d8b41b6525) should handle cases where an entry does not expose
the branch pathname (e.g., pointing to a device like /dev/zero).

README 

criu
====

An utility to checkpoint/restore tasks. Using this tool, you can
freeze a running application (or part of it) and checkpoint it to
a hard drive as a collection of files. You can then use the files
to restore and run the application from the point it was frozen
at. The distinctive feature of the CRIU project is that it is
mainly implemented in user space.

The project home is at http://criu.org

* A simple example of usage: http://criu.org/Simple_loop
* More sophisticated example with graphical app: http://criu.org/VNC
