Merge branch 'for-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue changes from Tejun Heo: "A lot of reorganization is going on mostly to prepare for worker pools with custom attributes so that workqueue can replace custom pool implementations in places including writeback and btrfs and make CPU assignment in crypto more flexible. workqueue evolved from purely per-cpu design and implementation, so there are a lot of assumptions regarding being bound to CPUs and even unbound workqueues are implemented as an extension of the model - workqueues running on the special unbound CPU. Bulk of changes this round are about promoting worker_pools as the top level abstraction replacing global_cwq (global cpu workqueue). At this point, I'm fairly confident about getting custom worker pools working pretty soon and ready for the next merge window. Lai's patches are replacing the convoluted mb() dancing workqueue has been doing with much simpler mechanism which only depends on assignment atomicity of long. For details, please read the commit message of 0b3dae68ac ("workqueue: simplify is-work-item-queued-here test"). While the change ends up adding one pointer to struct delayed_work, the inflation in percentage is less than five percent and it decouples delayed_work logic a lot more cleaner from usual work handling, removes the unusual memory barrier dancing, and allows for further simplification, so I think the trade-off is acceptable. There will be two more workqueue related pull requests and there are some shared commits among them. I'll write further pull requests assuming this pull request is pulled first." * 'for-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (37 commits) workqueue: un-GPL function delayed_work_timer_fn() workqueue: rename cpu_workqueue to pool_workqueue workqueue: reimplement is_chained_work() using current_wq_worker() workqueue: fix is_chained_work() regression workqueue: pick cwq instead of pool in __queue_work() workqueue: make get_work_pool_id() cheaper workqueue: move nr_running into worker_pool workqueue: cosmetic update in try_to_grab_pending() workqueue: simplify is-work-item-queued-here test workqueue: make work->data point to pool after try_to_grab_pending() workqueue: add delayed_work->wq to simplify reentrancy handling workqueue: make work_busy() test WORK_STRUCT_PENDING first workqueue: replace WORK_CPU_NONE/LAST with WORK_CPU_END workqueue: post global_cwq removal cleanups workqueue: rename nr_running variables workqueue: remove global_cwq workqueue: remove worker_pool->gcwq workqueue: replace for_each_worker_pool() with for_each_std_worker_pool() workqueue: make freezing/thawing per-pool workqueue: make hotplug processing per-pool ...
