io-wq: optimise out *next_work() double lock When executing non-linked hashed work, io_worker_handle_work() will lock-unlock wqe->lock to update hash, and then immediately lock-unlock to get next work. Optimise this case and do lock/unlock only once. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
