> - *	This test will verify that rename(2) syscall failed in EFAULT
> - *
> - * ALGORITHM
> - *	Setup:
> - *		Setup signal handling.
> - *		Create temporary directory.
> - *		Pause for SIGUSR1 if option specified.
> - *		Create a valid file to use in the rename() call.
> - *
> - *	Test:
> - *		Loop if the proper options are given.
> - *              1.  "old" is a valid file, newpath points to address
> - *                   outside allocated address space
> - *                  rename the "old" to the "new" file
> - *                  verify rename() failed with error EFAULT
> - *
> - *              2.  "old" points to address outside allocated address space
> - *                  ,"new" is a valid file
> - *                  rename the "old" to the "new"
> - *                  verify rename() failed with error EFAULT
> - *
> - *              3.  oldpath and newpath are all NULL
> - *                  try to rename NULL to NULL
> - *                  verify rename() failed with error EFAULT
> - *	Cleanup:
> - *		Print errno log and/or timing stats if options given
> - *		Delete the temporary directory created.*
> - * USAGE
> - *	rename08 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
> - *	where,  -c n : Run n copies concurrently.
> - *		-e   : Turn on errno logging.
> - *		-i n : Execute test n times.
> - *		-I x : Execute test for x seconds.
> - *		-P x : Pause for x seconds between iterations.
> - *		-t   : Turn on syscall timing.
