Originally, vdev_file used system_taskq. This would cause a deadlock, especially on system with few CPUs. The reason is that the prefetcher threads, which are on system_taskq, will sometimes be blocked waiting for I/O to finish. If the prefetcher threads consume all the tasks in system_taskq, the I/O cannot be served and thus results in a deadlock. We fix this by creating a dedicated vdev_file_taskq for vdev_file I/O.
