I've only shown the plain io_uring vs. linear systemcall here.

That is in principle a good idea. However, as Franz can tell you, for many uses cases predefining the followup actions does not work. For example, for reads, it can happen that you get a short read, whereby you cannot directly continue to the next action. chris -- Prof. Dr.-Ing.
