I'm really having a hard time doing any fuzzing after applying this patch. I'm not sure it's related directly, but the ldisc hangup lockup happens quite quickly and every time, so I can't really get any good fuzzing done. I'm not saying that this patch series is causing it, just saying that I can't really test it at this point due to that other lockup.
