2023-06-02io_uring: avoid indirect function calls for the hottest task_workJens Axboe
We use task_work for a variety of reasons, but doing completions or triggering rety after poll are by far the hottest two. Use the indirect funtion call wrappers to avoid the indirect function call if CONFIG_RETPOLINE is set. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-09-21io_uring/rw: don't lose partial IO result on failPavel Begunkov
A partially done read/write may end up in io_req_complete_failed() and loose the result, make sure we return the number of bytes processed.
