Would you test this patch?
You need to re-build whole kernel.

Hi J. R.,
I applied your patch to the 3.13.0-29-generic kernel on Ubuntu 14.04. I
ran some tests with /usr/bin/fallocate in a Docker 1.0 container, using 1-5
GB files. Everything seems to work fine. In particular, when the Docker
storage is on an ext4 partition, fallocate works as expected, and when I run
with the Docker storage on an ext3 partition, fallocate returns "Operation
not supported" as expected. Thanks!
Jeremy
