Hello, Call statfs(2) against a directory with project quota setup, the vanilla kernel-3.3 will crashed if the underlaying XFS file system was mounted without pquota option. For detail, please take a look at the following link for the bug report: http://patchwork.xfs.org/patch/3477/ I'd like to introduce a new test to verify something like this, it is intended to run as a negative test collections for project quota. It only verify the above issue for now, maybe its better to wrap the steps in a individual function?
