 * [Description]
 *
 * This testcases checks that quotactl(2) on xfs filesystem succeeds to:
 *
 * - turn off xfs quota and get xfs quota off status for user
 * - turn on xfs quota and get xfs quota on status for user
 * - set and use Q_XGETQUOTA to get xfs disk quota limits for user
 * - set and use Q_XGETNEXTQUOTA to get xfs disk quota limits greater than or
 *   equal to ID for user
 * - turn off xfs quota and get xfs quota off statv for user
 * - turn on xfs quota and get xfs quota on statv for user
 * - turn off xfs quota and get xfs quota off status for group
 * - turn on xfs quota and get xfs quota on status for group
 * - set and use Q_XGETQUOTA to get xfs disk quota limits for group
 * - set and use Q_XGETNEXTQUOTA to get xfs disk quota limits for group
 * - turn off xfs quota and get xfs quota off statv for group
 * - turn on xfs quota and get xfs quota on statv for gorup
