| * Description: |
| * This tests basic flags of quotactl() syscall: |
| * 1) Q_XQUOTAOFF - Turn off quotas for an XFS file system. |
| * 2) Q_XQUOTAON - Turn on quotas for an XFS file system. |
| * 3) Q_XGETQUOTA - Get disk quota limits and current usage for user id. |
| * 4) Q_XSETQLIM - Set disk quota limits for user id. |
| * 5) Q_XGETQSTAT - Get XFS file system specific quota information. |
