Nested checking @nxt for non-nullness in io_put_req_find_next() and friends is a nuisance. Make them accept only non-null @nxt obliging callers to io_queue_async_work() if they don't need @nxt. The patchset is a bit rusty (rebased), but still relevant. The part removing io_wq_current_is_worker() (PATCH 2/4) looks good, but would like someone to check the assumption. P.S. it depends on the patch with renaming __io_submit_sqe().
