workqueue has moved away from global_cwqs to worker_pools and with the scheduled custom worker pools, wforkqueues will be associated with pools which don't have anything to do with CPUs. The workqueue code went through significant amount of changes recently and mass renaming isn't likely to hurt much additionally. Let's replace 'cpu' with 'pool' so that it reflects the current design. * s/struct cpu_workqueue_struct/struct pool_workqueue/ * s/cpu_wq/pool_wq/ * s/cwq/pwq/ This patch is purely cosmetic.
