- * For a per-cpu workqueue, @max_active limits the number of in-flight work
- * items for each CPU. e.g. @max_active of 1 indicates that each CPU can be
- * executing at most one work item for the workqueue.
- *
- * For unbound workqueues, @max_active limits the number of in-flight work items
- * for the whole system. e.g. @max_active of 16 indicates that that there can be
- * at most 16 work items executing for the workqueue in the whole system.
- *
- * As sharing the same active counter for an unbound workqueue across multiple
- * NUMA nodes can be expensive, @max_active is distributed to each NUMA node
- * according to the proportion of the number of online CPUs and enforced
- * independently.
- *
- * Depending on online CPU distribution, a node may end up with per-node
- * max_active which is significantly lower than @max_active, which can lead to
- * deadlocks if the per-node concurrency limit is lower than the maximum number
- * of interdependent work items for the workqueue.
- *
- * To guarantee forward progress regardless of online CPU distribution, the
- * concurrency limit on every node is guaranteed to be equal to or greater than
- * min_active which is set to min(@max_active, %WQ_DFL_MIN_ACTIVE). This means
- * that the sum of per-node max_active's may be larger than @max_active.
