31  * The objective of this program is to provide a DMU/ZAP/SPA stress test
38  *     we have a simple routine to test that functionality.  These
41  * (2) We turn these simple functionality tests into a stress test by
53  *     we run the entire test in a child of the main process.
56  *     The parent then runs the test again, using the existing
65  *     If you add a new test, please do this if applicable.
71  * To turn this into an overnight stress test, use -T to specify run time.

3878 	 * Iteration 0 test zcopy for DB_UNCACHED dbufs.
3879 	 * Iteration 1 test zcopy to already referenced dbufs.
3880 	 * Iteration 2 test zcopy to dirty dbuf in the same txg.
3881 	 * Iteration 3 test zcopy to dbuf dirty in previous txg.
3882 	 * Iteration 4 test zcopy when dbuf is no longer dirty.
3883 	 * Iteration 5 test zcopy when it can't be done.
