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.
