[Users] Problem checkpointing VE with AUFS root

[Josiney de Souza]

Hi,

Junjiro from AUFS solves my problem. He gave a patch to apply in my kernel
sources. After the compilation, I tested checkpointing and retore a VE with
AUFS root and everthing works.

Attached, the patch for who wants to use AUFS and OpenVZ.
