It's easy enough to test. Just run usb.c in async mode (with test 15 or 16, ISO), a couple of times. Try it with and without the patch. Without the patch, when I exit usb.c the first time I get a cache-corruption error. Re-running it and exiting causes a hard lock-up. But with the patch everything works okay.
