Comment 10 for bug 1702979

I've confirmed that the PPA provided by @mwhudson in #4 addresses the crash reported in the issue.

I've also identified a simple test Dockerfile that crashes on an unpatched system, and works properly on the new PPA.

https://gist.github.com/bdafb8e961f55b2533fee8fa5221d186 - rename as "Dockerfile", then run

$ docker build -t deep-files .

With the PPA, this runs to completion; without it, it crashes at build time with

Step 41 : RUN mkdir 40
error creating aufs mount to /var/lib/docker/aufs/mnt/787c80e88d99c4ed74305f16ce
30395e3346cfa4629c3d078f9fab3c6e4e52f0: invalid argument

The Dockerfile is very simple; it just creates 100 directories, one layer at a time.
