Kind of related to the previous question, but I think we should just add
a single REGISTER opcode for this, and define a struct with the delay
setting. Add necessary padding for that, check padding for non-zero and
EINVAL if set. Then patch 3 can just add that struct field.
The IORING_REGISTER_NAPI can then also return the current settings by
just copying it back. That makes it a get/set API as well.
Patch 1 would be unaffected, this just changes patch 2+3 for the
io_uring API.
