I mean, it’s only a problem if your design is based on the Future having exclusive ownership of its read buffer, but io\_uring assumes a kind of shared ownership. The “obvious” solution is to encode that ownership model in the design, which implies some kind of cancellation mechanism. C and C++ programs have to do that too.
