      Recently Lustre has moved to using work queue but the trade off is that the work queues can run on any core. This will introduce noise which on clients means it has an performance impact on users application runs. The linux kernel offers a way to make binding to specific core possible with the function apply_workqueue_attrs() which can be passed a cpumask.
