- * NAME
- * linkat01.c
- *
- * DESCRIPTION
- * This test case will verify basic function of linkat
- * added by kernel 2.6.16 or up.
- *
- * USAGE: <for command-line>
- * linkat01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
- * where:
- * -c n : Run n copies simultaneously.
- * -e : Turn on errno logging.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -p : Pause for SIGUSR1 before starting
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *
- * Author
