      workqueue: factor out worker_pool from global_cwq · bd7bdd43
      Tejun Heo authored
      Move worklist and all worker management fields from global_cwq into
      the new struct worker_pool.  worker_pool points back to the containing
      gcwq.  worker and cpu_workqueue_struct are updated to point to
      worker_pool instead of gcwq too.
      
      This change is mechanical and doesn't introduce any functional
      difference other than rearranging of fields and an added level of
      indirection in some places.  This is to prepare for multiple pools per
      gcwq.
      
      v2: Comment typo fixes as suggested by Namhyung.

      workqueue: don't use WQ_HIGHPRI for unbound workqueues · 974271c4
      Tejun Heo authored
      Unbound wqs aren't concurrency-managed and try to execute work items
      as soon as possible.  This is currently achieved by implicitly setting
      %WQ_HIGHPRI on all unbound workqueues; however, WQ_HIGHPRI
      implementation is about to be restructured and this usage won't be
      valid anymore.
      
      Add an explicit chain-wakeup path for unbound workqueues in
      process_one_work() instead of piggy backing on %WQ_HIGHPRI.
