@argv_minus_one i ran btrfs-scrub on a 128GB disk converted from reiserfs and it said it was scrubbing 16GB. panicked until i saw df output then remembered that btrfs grows the file system as needed.

Yeah, there's also an in-place conversion from ext2/3/4.
I seem to recall reading that btrfs is very flexible about where all the on-disk structures are located, which makes it unusually amenable to in-place conversion from other file systems.
