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.
Cheers, Andreas
