> Could you use this to deduplicate files in a filesystem?
Depends on what you mean and your constraints. Deduplicate file entries if you can live with a rare false positives, sure. A setup of 1million entrie limit with 1/1billion false positive chance will get ~80M mem usage.
If you want to check for duplicate files, probably not.
