https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=159251 Xin LI <delphij@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|In Discussion |Issue Resolved CC| |delphij@FreeBSD.org Resolution|--- |Feature Proposal Rejected --- Comment #4 from Xin LI <delphij@FreeBSD.org> --- This feature is intentionally removed in OpenSolaris build 128 because fletcher4 is not endianness safe and caused problems for cross-endianness. On the other hand the collision rate is fairly high, making it not suitable as a dedup checksum. We may add some other faster checksum algorithms in the future but it's unlikely that fletcher4 will ever be added back as a dedup checksum. -- You are receiving this mail because: You are the assignee for the bug.
