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.
