Wed Dec 26 07:54:30 CET 2018
Testcase 1: AT_STATX_DONT_SYNC
With AT_STATX_DONT_SYNC server changes should not get sync with client.
Testcase 2: AT_STATX_FORCE_SYNC
With AT_STATX_FORCE_SYNC server changes should get sync with client.

+ * Test statx
+ *
+ * This code tests the following flags:
+ * 1) AT_STATX_FORCE_SYNC
+ * 2) AT_STATX_DONT_SYNC
+ *
+ * By exportfs cmd creating NFS setup.
+ *
+ * A test file is created in server folder and statx is being
+ * done in client folder.
+ *
+ * TESTCASE 1:
+ * BY AT_STATX_SYNC_AS_STAT getting predefined mode value.
+ * Then, by using AT_STATX_FORCE_SYNC getting new updated vaue
+ * from server file changes.
+ *
+ * TESTCASE 2:
+ * BY AT_STATX_SYNC_AS_STAT getting predefined mode value.
+ * AT_STATX_FORCE_SYNC is called to create cache data of the file.
+ * Then, by using DONT_SYNC_FILE getting old cached data in client folder,
+ * but mode has been chaged in server file.
