dduper is an offline dedupe tool. It works by fetching checksum from BTRFS
csum tree, instead of reading whole file blocks and computing checksum.
This tool relies on output from 'btrfs inspect-internal dump-csum' command.

Good time of day.
I have several questions about data deduplication on btrfs.
Sorry if i ask stupid questions or waste you time %)
What about implementation of offline data deduplication? I don't see
any activity on this place, may be i need

I do think however that having the option of a background thread doing
deduplication asynchronously is a good idea, but then you would have to
have some way to trigger it on individual files/trees, and triggering on
writes

Why does this have to be kernel side? There's userspace software already to
dedupe that can be run on a regular basis. Exporting checksums is a
differnet story (you can do that via ioctl) but running the dedupe software
