Add polled variants of the read and write commands. These act like their non-polled counterparts, except we expect to poll for completion of them.These aren't really need command variants, but a different type of context.

case IORING_OP_FSYNC: + if (ctx->flags & IORING_SETUP_IOPOLL) + break; ret = io_fsync(&req->fsync, iocb, false); break; case IORING_OP_FDSYNC: + if (ctx->flags & IORING_SETUP_IOPOLL) + break; ret = io_fsync(&req->fsync, iocb, true);I'd move this check into io_fsync to avoid a little duplication.
