[PATCH 0/3] workqueue: offload the worker-management out from kworker

From: Lai Jiangshan
Date: Fri Jul 25 2014 - 23:04:25 EST

Current kworker prefer creating worker (if required) to processing work items,
we hope the processing should be the first priority.

The jobs in managers are serialized, it is just wasting if we have multiple
managers, only one worker-creater is enough.

It causes much complication and tricky when manager is implemented inside
worker, using dedicated creater will make things more flexible.

So we offload the worker-management out from kworker into a single
dedicated creater kthread. It is done in patch2. And the patch1 is
preparation and patch3 is cleanup patch.

Lai Jiangshan (3):
workqueue: migrate the new worker before add it to idle_list
workqueue: use dedicated creater kthread for all pools
workqueue: cleanup may_start_working()
