Subject: [PATCH V2 00/15] workqueue: enhance locking and lookup worker via ID
Date: Tue, 19 Feb 2013 00:12:01 +0800 [thread overview]
Message-ID: <1361203940-6300-1-git-send-email-laijs@cn.fujitsu.com> (raw)
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
workqueue: queue worker to busy list
