Summary: Right now return codes by io_uring_submit_and_wait() and io_uring_wait_cqe() are not handled. It is not the good practice. Although these two functions are not supposed to return non-0 values in normal exeuction, people suspect that they might return non-0 value when an interruption happens, and the code might cause hanging. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8311 Test Plan: Make sure at least normal test cases still pass.
