The original test didn't produce any output results.
Use tst_macro to enable test to produce output results.

- *    DETAILED DESCRIPTION
- *     This is a Phase I test for the symlink(2) system call.  It is intended
- *     to provide a limited exposure of the system call, for now.  It
- *     should/will be extended when full functional tests are written for
- *     symlink(2).
- *
- *     Setup:
- *       Setup signal handling.
- *       Pause for SIGUSR1 if option specified.
- *
- *     Test:
- *      Loop if the proper options are given.
- *       Execute system call
- *       Check return code, if system call failed (return=-1)
- *             Log the errno and Issue a FAIL message.
- *       Otherwise, Issue a PASS message.
- *
- *     Cleanup:
- *       Print errno log and/or timing stats if options given

the fd is unnecessary in the test.
Yes.

Why do we need save the fd here, I didn't see any places make use of it.

Otherwise patchset looks good to me.

Yes, you are right. I overlooked this point.



-       TEST_PAUSE;
-
-       tst_tmpdir();
-
-       sprintf(fname, "tfile_%d", getpid());
-       if ((fd = open(fname, O_RDWR | O_CREAT, 0700)) == -1) {
-               tst_brkm(TBROK, cleanup,
-                        "open(%s, O_RDWR|O_CREAT,0700) Failed, errno=%d : %s",
-                        fname, errno, strerror(errno));
-       }
-
-       if (close(fd) == -1) {
-               tst_resm(TWARN, "close(%s) Failed, errno=%d : %s",
-                        fname, errno, strerror(errno));

remove the cleanup function.

OK.

 {
