Subject: xfstests failure generic/299

Hi Dmitry,

I've been noticing that the relatively new test #299 (which I didn't use
in the previous development cycle) is failing for me, both for the
current ext4 dev branch, as well as v3.9-rc5-1-g8cde7ad (the
origin/branch point from Linus's tree for the dev branch).

Is this test passing for you, and is there some patch whic I'm missing
which addresses this?

Thanks,

                                        - Ted
