Jens Axboe	c92fcfc2ba	io_uring: avoid indirect function calls for the hottest task_work ... 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>	2023-06-02 08:55:37 -06:00
Pavel Begunkov	47b4c68660	io_uring/rw: don't lose partial IO result on fail ... 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.
