      2  * NAME
      3  *	rename07
      4  *
      5  * DESCRIPTION
      6  *	This test will verify that rename(2) failed in ENOTDIR
      7  *
      8  * CALLS
      9  *	stat,open,rename,mkdir,close
     10  *
     11  * ALGORITHM
     12  *	Setup:
     13  *		Setup signal handling.
     14  *		Create temporary directory.
     15  *		Pause for SIGUSR1 if option specified.
     16  *              create the "old" directory and the "new" file
     17  *              rename the "old" directory to the "new" file
     18  *
     19  *	Test:
     20  *		Loop if the proper options are given.
     21  *                  verify rename() failed and returned ENOTDIR
     22  *
     23  *	Cleanup:
     24  *		Print errno log and/or timing stats if options given
     25  *		Delete the temporary directory created.*
     26  * USAGE
     27  *	rename07 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
     28  *	where,  -c n : Run n copies concurrently.
     29  *		-e   : Turn on errno logging.
     30  *		-i n : Execute test n times.
     31  *		-I x : Execute test for x seconds.
     32  *		-P x : Pause for x seconds between iterations.
     33  *		-t   : Turn on syscall timing.
