27 queue is called workqueue and the thread is called worker.
29 While there are work items on the workqueue the worker executes the
31 there is no work item left on the workqueue the worker becomes idle.
32 When a new work item gets queued, the worker begins executing again.

66 * Use per-CPU unified worker pools shared by all wq to provide

92 which manages worker-pools and processes the queued work items.
94 There are two worker-pools, one for normal work items and the other
96 worker-pools to serve work items queued on unbound workqueues - the
107 When a work item is queued to a workqueue, the target worker-pool is
109 and appended on the shared worklist of the worker-pool.  For example,

114 For any worker pool implementation, managing the concurrency level
120 Each worker-pool bound to an actual CPU implements concurrency
121 management by hooking into the scheduler.  The worker-pool is notified
122 whenever an active worker wakes up or sleeps and keeps track of the
127 workers on the CPU, the worker-pool doesn't start execution of a new
128 work, but, when the last running worker goes to sleep, it immediately
129 schedules a new worker so that the CPU doesn't sit idle while there
