From: "chenhx.fnst@fujitsu.com" <chenhx.fnst@fujitsu.com>

Removed MS_SYNCHRONOUS test as the test was bogus (see issue #960).
Renamed child file to be obvious it's a fork.

Changes v3->v4:
* remove commit which created TST_EXP_EQ_STR
* remove MS_SYNCHRONOUS test as being bogus, see
https://github.com/linux-test-project/ltp/issues/960
* fix license
* check child test result with tst_reinit()
* put back more verbose docparse
* remove TST_RESOURCE_COPY(), copy file to MNTPOINT, so that it's used
  for all filesystems. This somehow requires to use
  TST_RETRY_FN_EXP_BACKOFF() to make sure file is written (randomly
  problem for at least ext[34])
* rename child file

- * DESCRIPTION
- *	Check for basic mount(2) system call flags.
+/*\
+ * [Description]
  *
- *	Verify that mount(2) syscall passes for each flag setting and validate
- *	the flags
- *	1) MS_RDONLY - mount read-only.
- *	2) MS_NODEV - disallow access to device special files.
- *	3) MS_NOEXEC - disallow program execution.
- *	4) MS_SYNCHRONOUS - writes are synced at once.
- *	5) MS_REMOUNT - alter flags of a mounted FS.
- *	6) MS_NOSUID - ignore suid and sgid bits.
- *	7) MS_NOATIME - do not update access times.
+ * Check mount(2) system call with various flags.
+ *
+ * Verify that mount(2) syscall passes for each flag setting and validate
+ * the flags:
+ *
+ * - MS_RDONLY - mount read-only
+ * - MS_NODEV - disallow access to device special files
+ * - MS_NOEXEC - disallow program execution
+ * - MS_REMOUNT - alter flags of a mounted FS
+ * - MS_NOSUID - ignore suid and sgid bits
+ * - MS_NOATIME - do not update access times
