Alexander Motin 41878d57ea Add BRT support to zpool prefetch command ... Implement BRT (Block Reference Table) prefetch functionality similar to existing DDT prefetch. This allows preloading BRT metadata into ARC to improve performance for block cloning operations and frees of earlier cloned blocks. Make -t parameter optional. When omitted, prefetch all supported metadata types (both DDT and BRT now).
