Title:
  Regression in overlayfs

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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.
