+config SCHED_WORKQUEUE

+	---help---
+		Create a dedicated "worker" thread to handle delayed processing from interrupt
+		handlers.  This feature is required for some drivers but, if there are no
+		complaints, can be safely disabled.  The worker thread also performs
+		garbage collection -- completing any delayed memory deallocations from
+		interrupt handlers.  If the worker thread is disabled, then that clean up will
+		be performed by the IDLE thread instead (which runs at the lowest of priority
+		and may not be appropriate if memory reclamation is of high priority).
