Tejun Heo c9178087ac workqueue: perform non-reentrancy test when queueing to unbound workqueues too ... Because per-cpu workqueues have multiple pwqs (pool_workqueues) to serve the CPUs, to guarantee that a single work item isn't queued on one pwq while still executing another, __queue_work() takes a look at the previous pool the target work item was on and if it's still executing there, queue the work item on that pool. To support changing workqueue_attrs on the fly, unbound workqueues too will have multiple pwqs and thus need non-reentrancy test when queueing. This patch modifies __queue_work() such that the reentrancy test is performed regardless of the workqueue type. per_cpu_ptr(wq->cpu_pwqs, cpu) used to be used to determine the matching pwq for the last pool. This can't be used for unbound workqueues and is replaced with worker->current_pwq which also happens to be simpler.
