Hi guys,

I'm contemplating implementing a new fast hash algorithm in Illumos' ZFS
implementation to supplant the currently utilized sha256. On modern
64-bit CPUs SHA-256 is actually much slower than SHA-512 and indeed much
slower than many of the SHA-3 candidates, so I went out and did some
testing (details attached) on a possible new hash algorithm that might
improve on this situation.

Is the intent to store the 512 bit hash or truncate to 256 bit?
