Public bug reported:

When installing the linux-lts-vivid kernel in Ubuntu 14.04, there is a
regression with overlayfs and unprivileged containers: 'failed to
whiteout'

Below the system information:

- Kernel error: http://pastebin.com/iajXHbHZ
- Kernel version: 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
- Executed LXC command: lxc-clone -s -B overlayfs orig test (both unprivileged containers)
- LXC version: 1.0.7

We discussed this on the LXC user mailing list, and this is likely a bug
in one of the patches that add support for unprivileged use of
overlayfs.
