* [Description]
|
||
|
|
* This testcases checks that quotactl(2) on ext4 filesystem succeeds to:
|
||
|
|
*
|
||
|
|
* - turn on quota with Q_QUOTAON flag for user
|
||
|
|
* - set disk quota limits with Q_SETQUOTA flag for user
|
||
|
|
* - get disk quota limits with Q_GETQUOTA flag for user
|
||
|
|
* - set information about quotafile with Q_SETINFO flag for user
|
||
|
|
* - get information about quotafile with Q_GETINFO flag for user
|
||
|
|
* - get quota format with Q_GETFMT flag for user
|
||
|
|
* - update quota usages with Q_SYNC flag for user
|
||
|
|
* - get disk quota limit greater than or equal to ID with Q_GETNEXTQUOTA flag for user
|
||
|
|
* - turn off quota with Q_QUOTAOFF flag for user
|
||
|
|
* - turn on quota with Q_QUOTAON flag for group
|
||
|
|
* - set disk quota limits with Q_SETQUOTA flag for group
|
||
|
|
* - get disk quota limits with Q_GETQUOTA flag for group
|
||
|
|
* - set information about quotafile with Q_SETINFO flag for group
|
||
|
|
* - get information about quotafile with Q_GETINFO flag for group
|
||
|
|
* - get quota format with Q_GETFMT flag for group
|
||
|
|
* - update quota usages with Q_SYNC flag for group
|
||
|
|
* - get disk quota limit greater than or equal to ID with Q_GETNEXTQUOTA flag for group
|
||
|
|
* - turn off quota with Q_QUOTAOFF flag for group
|
||
|
|
*
|
||
|
|
* It is similar to quotactl01.c, only two difference
|
||
|
|
* - use new quotactl_fd syscalls if supports
|
||
|
|
* - quota file hidden in filesystem
|
||
|
|
*
|
||
|
|
* Minimum e2fsprogs version required is 1.43.
