     21  * NAME
     22  *	rename10
     23  *
     24  * DESCRIPTION
     25  *	This test will verify that rename(2) syscall fails with ENAMETOOLONG
     26  *      and ENOENT
     27  *
     28  * ALGORITHM
     29  *	Setup:
     30  *		Setup signal handling.
     31  *		Create temporary directory.
     32  *		Pause for SIGUSR1 if option specified.
     33  *              create the "old" file
     34  *
     35  *	Test:
     36  *		Loop if the proper options are given.
     37  *              1.  rename the "old" to the "new" file
     38  *                  verify rename() failed with error ENAMETOOLONG
     39  *
     40  *              2.  "new" path contains a directory that does not exist
     41  *                  rename the "old" to the "new"
     42  *                  verify rename() failed with error ENOENT
     43  *	Cleanup:
     44  *		Print errno log and/or timing stats if options given
     45  *		Delete the temporary directory created.*
     46  *
     47  * USAGE
     48  *	rename10 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
     49  *	where,  -c n : Run n copies concurrently.
     50  *		-e   : Turn on errno logging.
     51  *		-i n : Execute test n times.
     52  *		-I x : Execute test for x seconds.
     53  *		-P x : Pause for x seconds between iterations.
     54  *		-t   : Turn on syscall timing.
