System workqueue


–          binder_deferred_workqueue = create_singlethread_workqueue(“binder”);

–          queue_work(binder_deferred_workqueue, &binder_deferred_work);

+         schedule_work(&binder_deferred_work);

  • Binder is the RPC mechanism used on androids. The workqueue is being used to run deferred work for the android binder.
  • The “binder_deferred_workqueue” queues only a single work item and hence does not require ordering.
  • Also, this workqueue is not being used on a memory reclaim path.
  • Hence, it has been converted to use system_wq.



Used when the work items don’t take very long and can be run concurrently.

No special flags required..

BEST option in these cases!
