Date: Wed Mar 5 14:03:34 2025 -0700 io_uring/rw: ensure reissue path is correctly handled for IOPOLL The IOPOLL path posts CQEs when the io_kiocb is marked as completed, so it cannot rely on the usual retry that non-IOPOLL requests do for read/write requests. If -EAGAIN is received and the request should be retried, go through the normal completion path and let the normal flush logic catch it and reissue it, like what is done for !IOPOLL reads or writes.
