staging: lustre: lnet: convert selftest to use workqueues
Instead of the cfs workitem library, use workqueues. As lnet wants to provide a cpu mask of allowed cpus, it needs to be a WQ_UNBOUND work queue so that tasks can run on cpus other than where they were submitted. This patch also exported apply_workqueue_attrs() which is a documented part of the workqueue API, that isn't currently exported. lustre needs it to allow workqueue thread to be limited to a subset of CPUs. Acked-by: Tejun Heo <tj@kernel.org> (for export of apply_workqueue_attrs) Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
