This PR condenses the FDT dedup log syncing into a single sync pass. This reduces the overhead of modifying indirect blocks for the dedup table multiple times per txg. In addition, changes were made to the formula for how much to sync per txg. We now also consider the backlog we have to clear, to prevent it from growing too large, or remaining large on an idle system. Sponsored-by: Klara, Inc. Sponsored-by: iXsystems, Inc.
