io_uring: add IOSQE_ASYNC io_uring defaults to always doing inline submissions, if at all possible. But for larger copies, even if the data is fully cached, that can take a long time. Add an IOSQE_ASYNC flag that the application can set on the SQE - if set, it'll ensure that we always go async for those kinds of requests. Use the io-wq IO_WQ_WORK_CONCURRENT flag to ensure we get the concurrency we desire for this case. Signed-off-by: Jens Axboe <axboe@kernel.dk>
