Core patches are patch 1, patch 9, patch 13

Patch 1: enhance locking
Patch 9: recorde worker id to work->data instead of pool id
	 lookup worker via worker ID if offq
Patch 13:also lookup worker via worker ID if running&&queued,
	 remove lookup via hashtable

Patch 6-8: ensure modification to worker->pool is under pool lock held
Patch 14: remove hashtable totally

other patch is preparing-patch or cleanup.


Lai Jiangshan (15):
  workqueue: add lock_work_pool()
  workqueue: allow more work_pool id space
  workqueue: remname worker->id to worker->id_in_pool
  workqueue: add worker's global worker ID
  workqueue: only set pool id when the work is running
  workqueue: use current instead of worker->task in
    worker_maybe_bind_and_lock()
  workqueue: change argument of worker_maybe_bind_and_lock() to pool
  workqueue: only change worker->pool with pool lock held
  workqueue: use worker id instead
  workqueue: avoid unneeded calls to get_work_cwq(work)
  workqueue: split work_flags to delayed_flags and color_flags in
    __queue_work()
  workqueue: add extra flags to set_work_worker_and_keep_pending()
  workqueue: also record worker in work->data if running&&queued
  workqueue: convert busy hash to busy list
