Specifically, I don't see a Fingerprint256() function in FarmHash, so no 256-bit fingerprints (unless I am missing something?). Also, it seems that FarmHash's Fingerprint128() hash is just CityHash128(). Unless I am misreading it, I think FarmHash is mostly useful for 32-bit and 64-bit hashes. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
