Hello people, I have a question regarding workqueues. I know it's possible to sleep in workqueue routines. Does that mean I can use: 1. "set_current_state(TASK_INTERRUPTIBLE);" get the the task with "current" and pass it to a other task and then call "schedule();" in a workqueue routine and at a different place (perhaps another workqueue routine) use wake_up_process(task)" ? 2. initialize completions in a workqueue routine and call complete() in a different workqueue routine? I tried it in a simple example setup and both worked. I just want to make sure that was not just by accident. As I understand it a work item is executed on a worker, which is a unique process, but I also know that there are exceptions, e.g. I can not copy to or from user space in a workqueue routine. Also I don't know if a worker "sticks" with the current work item until it is completed or can execute multiple work items at the "same" time. 3. In case completions and schedule()/wakeup() work, I would also like to know, which has the better performance. Thanks a lot already!
