* crypto: qat - Remove deprecated create_workqueueBhaktipriya Shridhar2016-06-133-3/+4
| | | | | | | | | | | | | | | | | | | | | | alloc_workqueue replaces deprecated create_workqueue(). The workqueue device_reset_wq has workitem &reset_data->reset_work per adf_reset_dev_data. The workqueue pf2vf_resp_wq is a workqueue for PF2VF responses has workitem &pf2vf_resp->pf2vf_resp_work per pf2vf_resp. The workqueue adf_vf_stop_wq is used to call adf_dev_stop() asynchronously. Dedicated workqueues have been used in all cases since the workitems on the workqueues are involved in operation of crypto which can be used in the IO path which is depended upon during memory reclaim. Hence, WQ_MEM_RECLAIM has been set to gurantee forward progress under memory pressure. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | VFs call adf_dev_stop() from a PF to VF interrupt bottom half. This causes an oops "scheduling while atomic", because it tries to acquire a mutex to un-register crypto algorithms. This patch fixes the issue by calling adf_dev_stop() asynchronously.
