     21  * NAME
     22  *	rename06
     23  *
     24  * DESCRIPTION
     25  *	This test will verify that rename(2) failed in EINVAL
     26  *
     27  * ALGORITHM
     28  *	Setup:
     29  *		Setup signal handling.
     30  *		Create temporary directory.
     31  *		Pause for SIGUSR1 if option specified.
     32  *              create the "old" directory
     33  *              create the "new" directory under the "old" directory
     34  *
     35  *	Test:
     36  *		Loop if the proper options are given.
     37  *                  rename the "old" to the "new" directory
     38  *                  verify rename() failed and returned EINVAL
     39  *
     40  *	Cleanup:
     41  *		Print errno log and/or timing stats if options given
     42  *		Delete the temporary directory created.
     43  *
     44  * USAGE
     45  *	rename06 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
     46  *	where,  -c n : Run n copies concurrently.
     47  *		-e   : Turn on errno logging.
     48  *		-i n : Execute test n times.
     49  *		-I x : Execute test for x seconds.
     50  *		-P x : Pause for x seconds between iterations.
     51  *		-t   : Turn on syscall timing.
