8 * [Description]
9 * This testcases checks that quotactl(2) on ext4 filesystem succeeds to:
10 *
11 * - turn on quota with Q_QUOTAON flag for user
12 * - set disk quota limits with Q_SETQUOTA flag for user
13 * - get disk quota limits with Q_GETQUOTA flag for user
14 * - set information about quotafile with Q_SETINFO flag for user
15 * - get information about quotafile with Q_GETINFO flag for user
16 * - get quota format with Q_GETFMT flag for user
17 * - update quota usages with Q_SYNC flag for user
18 * - get disk quota limit greater than or equal to ID with Q_GETNEXTQUOTA flag for user
19 * - turn off quota with Q_QUOTAOFF flag for user
20 * - turn on quota with Q_QUOTAON flag for group
21 * - set disk quota limits with Q_SETQUOTA flag for group
22 * - get disk quota limits with Q_GETQUOTA flag for group
23 * - set information about quotafile with Q_SETINFO flag for group
24 * - get information about quotafile with Q_GETINFO flag for group
25 * - get quota format with Q_GETFMT flag for group
26 * - update quota usages with Q_SYNC flag for group
27 * - get disk quota limit greater than or equal to ID with Q_GETNEXTQUOTA flag for group
28 * - turn off quota with Q_QUOTAOFF flag for group
29 *
30 * It is similar to quotactl01.c, only two difference
31 *
32 * - use new quotactl_fd syscalls if supports
33 * - quota file hidden in filesystem
34 *
35 * Minimum e2fsprogs version required is 1.43.
