Good morning, I'm working on an offline deduplication script intended to
work around the copy-on-write functionality of BTRFS.
Simply put - is there any existing utility to compare two files (or
dirs) and output if the files share the same physical extents / data
blocks on disk?

Yes, this is useful, thanks. I'm thinking if it's ok to stop on
first error, ie. when the subvolume does n

div_factor{_fine} has been implemented for two times, and these two functions
are very similar, so cleanup the reduplicate implement and drop the original
div_factor(), and then rename div_factor_fine() to div_factor(). So the divisor
