- * NAME
- *	rename05
- *
- * DESCRIPTION
- *	This test will verify that rename(2) fails with EISDIR
- *
- * ALGORITHM
- *	Setup:
- *		Setup signal handling.
- *		Create temporary directory.
- *		Pause for SIGUSR1 if option specified.
- *              create the "old" file and the "new" directory
- *              rename the "old" file to the "new" directory
- *
- *	Test:
- *		Loop if the proper options are given.
- *                  verify rename() failed and returned EISDIR
- *
- *	Cleanup:
- *		Print errno log and/or timing stats if options given
- *		Delete the temporary directory created.
- *
- * USAGE
- *	rename05 [-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.
- *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS
- *	None.
+/*\
+ * [Description]
+ * Verify that rename(2) fails with EISDIR when
+ * oldpath is not a directory and newpath is an existing directory.
