Orlov is the name of the INODE allocator, not the block allocator. I'm not sure there is a name for the block allocator except "old" or "bitmap". In the future I suspect we won't want to keep this version at all, using the mballoc allocator even for block-mapped files, but it is useful for now for performance comparisons.
