Rather than use a new opcode for this, why don't we just add it to the existing NOP? I know we don't check for flags in currently, so you would not know if it worked, but we could add that and just backport that one-liner as well. And if we had such a flag, the fail res could be passed in as well. -- Jens Axboe
