Hui Su f5741d2b34 sched/core: Call wq_worker_tick() for the execution context ... wq_worker_tick() accounts CPU time and detects CPU-intensive work for the kworker that is actually running. With proxy execution, rq->donor is the scheduling context while rq->curr is the execution context. Calling the hook with rq->donor can skip workqueue accounting when a kworker is executing on behalf of a donor task. It can also account a blocked kworker when the donor is a worker but rq->curr is the task actually executing. The former can delay WORKER_CPU_INTENSIVE handling and pool concurrency management, which can delay pending kernel work and userspace operations depending on it. Use rq->curr for the workqueue tick hook while retaining rq->donor for scheduler accounting.
