If you scan from the root subvolume you're guanteed to traverse every file on the filesystem (which is all that can be deduped) without crossing any filesystem boundaries. Even if you have btrfs on non-btrfs on btrfs there must be some other path that reaches the same files when scanning from subvolid 0. -- Rich -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
