This enables kernel callers (io_uring, bpf, etc.) to invoke getsockopt directly. The setsockopt() conversion previously used sockptr, but Linus objected to that approach and suggested iov_iter instead. For full context, see: https://lore.kernel.org/all/[email protected]/ > It does add a lot more complexity and makes the code less obvious. I agree this adds complexity. Unfortunately, I don't see a simpler way to enable getsockopt to work with non-__user addresses.
