Oracle Solaris 11 Express - ZFS

[grarpamp]

Is this release the first example of their stated[?] plan in action
to be releasing source code only in step with releases for things
like ZFS to the community (IllumOS, BSD's, etc)?
Particularly regarding diff and crypto (and maybe some
dedup and compression stuff) as now present in this release.
Not a request, just is this what we're seeing?
Or about to see released?
