Chunwei Chen da8f51e16a Use a dedicated taskq for vdev_file ... The introduction of parallel zvol prefetch causes deadlock when using vdev_file. spa_async->(spa_namespace_lock)->txg_wait_synced->(wait for txg_sync) txg_sync->zio_wait->(wait for vdev_file_io_fsync on system_taskq) zvol_prefetch_minors_impl (on system_taskq)->spa_open_common->(wait for spa_namespace_lock) We fix this by using dedicated taskq for vdev_file. This same change was originally made in commit bc25c93 but reverted in commit aa9af22 when dynamic taskqs were added.
