- Issue prescient prefetches for demand indirect blocks after the first one. It should be quite rare for reads/writes, but much more useful for cloning due to much bigger (up to 1022 blocks) accesses. It covers the gap during the first couple accesses when we can not speculate yet, but we know what is needed right now. It reduces dbuf_hold() sync read delays in dmu_buf_hold_array_by_dnode(). - Increase maximum prefetch distance for indirect blocks from 64 to 128MB. It should cover the maximum 1022 blocks of block cloning access size in case of default 128KB recordsize used. In case of bigger recordsize the above prescient prefetch should also help.
