60 * Use per-CPU unified worker pools shared by all wq to provide
83 called worker-pools.
85 The cmwq design differentiates between the user-facing workqueues that
87 which manages worker-pools and processes the queued work items.
89 There are two worker-pools, one for normal work items and the other
91 worker-pools to serve work items queued on unbound workqueues - the
102 When a work item is queued to a workqueue, the target worker-pool is
104 and appended on the shared worklist of the worker-pool.  For example,
106 be queued on the worklist of either normal or highpri worker-pool that
115 Each worker-pool bound to an actual CPU implements concurrency
116 management by hooking into the scheduler.  The worker-pool is notified
122 workers on the CPU, the worker-pool doesn't start execution of a new
144 wq's that have a rescue-worker reserved for execution under memory
145 pressure.  Else it is possible that the worker-pool deadlocks waiting
