How many times does it take? No, and I'm not looking for you. You have the burden of proof. You yourself claimed you hadn't audited the things. The question this raised was rather obvious: If you didn't even look at them, how do you have any idea it's going to work for them? All that needs to be supplied is sufficient evidence, collected from 20 spots around the VM (arch code), and for that matter, in summary form ("I audited all architectures"). This should not be in the form of a lie, not to imply you would do that. The sparc64 analysis you gave is actually somewhat off but it doesn't really matter so long as there's actual diligence instead of simultaneous claims of sufficiency and non-diligence. I am not even looking at the code. I have my own work to do. I respectfully ask that when you do your own, you exercise the kind of diligence I described above as opposed to the kind of affiar you described in your announcement. -- wli -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
