I know that IORING_SETUP_COOP_TASKRUN actually schedules any system calls as they occur.

IORING_SETUP_ATTACH_WQ is for some io_uring to share the asynchronous thread backend.

io_uring_register_iowq_aff is to register the affinity of the asynchronous threads.

So am I right in guessing that IORING_SETUP_ATTACH_WQ and io_uring_register_iowq_aff have no effect on IORING_SETUP_COOP_TASKRUN?
