I'm not suggesting using io-uring cmd as a configuration alternative to configfd, I'm suggesting it can be an async *vehicle* for a bunch of configurations one might need to make in the kernel. If we want to reduce system call uses, we may want to allow something like configfd to accept a batch of configuration options as well, as a batcha, and a final commit to process them. Luis
