Btrfs doesn't directly support bad blocks. But since the conversion is supposed to use only "free space" that's presumably excluding bad blocks (which are presumably counted as allocated).

Doesn't support bad blocks at all.

Bad blocks don't count as allocated unless they are newly discovered - data should be moved asap if it's still recoverable. An allocated block with nothing in it is an error.
