I've got a bug I'm having trouble identifying. It seems like it could be related to my work_struct usage. I essentially have this: struct my_worker { work_struct work; /* some other data */ }; void worker_fn(struct work_struct *work) { struct my_worker *worker = container_of(work, struct my_worker, work); /* ... do some stuff ... */ kfree(worker); } void worker_caller() { struct my_worker *worker = kmalloc(sizeof(*worker), GFP_KERNEL); INIT_WORK(&worker->work, worker_fn); /* ... add some other stuff to *worker ... */ schedule_work(&worker->work); } I frequently get a kernel panic with a specific test, but the stack trace is rarely the same, which seems to indicate to me that I'm corrupting data somewhere. So my question is: Can I free the memory for "struct my_worker *worker" inside worker_fn? Or does the work_queue stuff need to continue to use the "struct work_struct work" member after the end of worker_fn? -Kai Meyer
