This is as much an upstream compatibility as it's a bit of a performance gain. The illumos taskq implemention doesn't allow a TASKQ_THREADS_CPU_PCT type to be dynamic and in fact enforces as much with an ASSERT. As to performance, if this taskq is dynamic, it can cause excessive contention on tq_lock as the threads are created and destroyed because it can see bursts of many thousands of tasks in a short time, particularly in heavy high-concurrency zvol write workloads.
