| * This testcase checks the basic flag of quotactl(2) for non-XFS filesystems: |
| * 1) quotactl(2) succeeds to turn on quota with Q_QUOTAON flag for user. |
| * 2) quotactl(2) succeeds to set disk quota limits with Q_SETQUOTA flag |
| * for user. |
| * 3) quotactl(2) succeeds to get disk quota limits with Q_GETQUOTA flag |
| * for user. |
| * 4) quotactl(2) succeeds to set information about quotafile with Q_SETINFO |
| * flag for user. |
| * 5) quotactl(2) succeeds to get information about quotafile with Q_GETINFO |
| * flag for user. |
| * 6) quotactl(2) succeeds to get quota format with Q_GETFMT flag for user. |
| * 7) quotactl(2) succeeds to update quota usages with Q_SYNC flag for user. |
| * 8) quotactl(2) succeeds to get disk quota limit greater than or equal to |
| * ID with Q_GETNEXTQUOTA flag for user. |
| * 9) quotactl(2) succeeds to turn off quota with Q_QUOTAOFF flag for user. |
| * 10) quotactl(2) succeeds to turn on quota with Q_QUOTAON flag for group. |
| * 11) quotactl(2) succeeds to set disk quota limits with Q_SETQUOTA flag |
| * for group. |
| * 12) quotactl(2) succeeds to get disk quota limits with Q_GETQUOTA flag |
| * for group. |
| * 13) quotactl(2) succeeds to set information about quotafile with Q_SETINFO |
| * flag for group. |
| * 14) quotactl(2) succeeds to get information about quotafile with Q_GETINFO |
| * flag for group. |
| * 15) quotactl(2) succeeds to get quota format with Q_GETFMT flag for group. |
| * 16) quotactl(2) succeeds to update quota usages with Q_SYNC flag for group. |
| * 17) quotactl(2) succeeds to get disk quota limit greater than or equal to |
| * ID with Q_GETNEXTQUOTA flag for group. |
| * 18) quotactl(2) succeeds to turn off quota with Q_QUOTAOFF flag for group. |
