This was fletcher4 earlier, and still is in opensolaris/openindiana. Given a
combination with verify (which I would use anyway, since there are always tiny

fletcher4 was only an option for snv_128, which was quickly pulled and
replaced with snv_128b which removed fletcher4 as an option.

It looks like fletcher4 is still an option in snv_151a for non-dedup
datasets, and is in fact the default.
As an aside: Erik, any idea when the 159 bits will make it to the public?

Yup, fletcher4 is still the default for any fileset not using dedup.
It's "good enough", and I can't see any reason to change it for those
purposes (since it's collision problems aren't much of an issue when
just doing data integrity checks).
Sorry, no idea on release date stuff. I'm completely out of the loop on
release info. I'm lucky if I can get a heads up before it actually gets
published internally.

I'm just a lowly Java Platform Group dude. Solaris ain't my silo.
