alloc_workqueue replaces deprecated create_workqueue(). create_workqueue has been replaced with alloc_workqueue with max_active as 0 since there is no need for throttling the number of active work items. WQ_MEM_RECLAIM has not been set to because kfd_process_wq will not be used in memory reclaim path. kfd_process_wq is used for delay destruction. A work item embedded in kfd_process gets queued to kfd_process_wq and when it executes it destroys and frees the containing kfd_process and thus itself. This requires a dedicated workqueue because a work item once queued, may get freed at any point of time and any external entity cannot flush the work item. So, in order to wait for such a work item, it needs to be put on a dedicated workqueue. kfd_module_exit() calls kfd_process_destroy_wq which ensures that all pending work items are finished before the module is removed. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty. Hence flush_workqueue has been removed. Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Acked-by: Tejun Heo <tj@kernel.org> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> |
