- * A workitems is deferred work with these semantics:
- * - a workitem always runs in thread context.
- * - a workitem can be concurrent with other workitems but is strictly
- * serialized with respect to itself.
- * - no CPU affinity, a workitem does not necessarily run on the same CPU
- * that schedules it. However, this might change in the future.
- * - if a workitem is scheduled again before it has a chance to run, it
- * runs only once.
- * - if a workitem is scheduled while it runs, it runs again after it
- * completes; this ensures that events occurring while other events are
- * being processed receive due attention. This behavior also allows a
- * workitem to reschedule itself.
- *
- * Usage notes:
- * - a workitem can sleep but it should be aware of how that sleep might
- * affect others.
- * - a workitem runs inside a kernel thread so there's no user space to access.
- * - do not use a workitem if the scheduling latency can't be tolerated.
- *
- * When wi_action returns non-zero, it means the workitem has either been
- * freed or reused and workitem scheduler won't touch it any more.
