+ * Tests basic error handling of the quotactl syscall without visible quota files
+ * (use quotactl and quotactl_fd syscall):

+ * 1) quotactl fails with EFAULT when addr or special is invalid.
+ *
+ * 2) quotactl fails with EINVAL when cmd or type is invalid.
+ *
+ * 3) quotactl fails with ENOTBLK when special is not a block device.
+ *
+ * 4) quotactl fails with ERANGE when cmd is Q_SETQUOTA, but the
+ * specified limits are out of the range allowed by the quota format.
+ *
+ * 5) quotactl fails with EPERM when the caller lacked the required
+ * privilege (CAP_SYS_ADMIN) for the specified operation.

This case is similar to quotactl06 but only two differences 1) use quotactl and quotactl_fd syscalls without visible quota file 2) remove some error for addr argument Signed-off-by: Yang Xu <xuyang2018.jy@fujitsu.com> --- runtest/syscalls | 1 + testcases/kernel/syscalls/quotactl/.gitignore | 1 + .../kernel/syscalls/quotactl/quotactl09.c | 179 ++++++++++++++++++ 3 files changed, 181 insertions(+) create mode 100644 testcases/kernel/syscalls/quotactl/quotactl09.c
