Are there any plans to support coroutine for syscall?

non-blocking IO service with coroutine.

Describe the solution you'd like
For example, combine epoll/io_uring with libcopp via hooking syscalls, like Tencent/libco. Then we can call IO operateration without considering blocking api.

No, ther is no plan.
Hooks of IO APIs will limit the IO/Event system and the ways differ from platform. Many large project have it's own event system.
libco only support linux, and some other implementation of coroutine hooks are limited to specify IO libraries.

The better practice is implementing these hooks as a plugin or a module of some application framework and using it's own executors and coroutine libraries.
