[LTP] [PATCH v1 07/11] syscalls/quotactl08: Test quoatctl01 but quota info hidden in filesystem

Mon Oct 18 15:14:44 CEST 2021
It uses two variants(quotactl and quotactl_fd). The difference for quotactl01
is that we don't use quotacheck command and quota info hidden in filesystem.

+ * 5) quotactl(2) succeeds to get information about quotafile with Q_GETINFO
