Description

When a chroot is called for a directory which was mounted with cephfs the kernel crashes.

The same happens (or at least similair) when a lxc-start is used.

This is on 64-bit Ubuntu 12.10 running under KVM on a Ubuntu 12.04.1 LTS both with a standard install and up to date (maybe the VM is a bit behind on updates as it is just a test VM).

I can test more, because I can reproduce it easily.
