This exposes a variety of per-taskq stats under /proc/spl/kstat/taskq, one file per taskq, named for the taskq name.instance. These include a small amount of info about the taskq config, the current state of the threads and queues, and various counters for thread and queue activity since the taskq was created. To assist with decrementing queue size counters, the list an entry is on is encoded in spare bits in the entry flags.
