This change adds a new `zpool prefetch -t ddt $pool` command which causes a pool's DDT to be loaded into the ARC. The primary goal is to remove the need to "warm" a pool's cache before deduplication stops slowing write performance. It may also provide a way to reload portions of a DDT if they have been flushed due to inactivity. Sponsored-by: iXsystems, Inc. Sponsored-by: Catalogics, Inc. Sponsored-by: Klara, Inc.
