Both, really. Last I heard when I poked at the subject was that Sun's license for ZFS was not compatible with GPL, and therefor excludes it from candidacy for inclusion in the Linux kernel.

Well, given the number of non-free modules that Linux already includes, I find it suspicious that they suddenly get that Old Time Religion(tm) with respect to ZFS.

Although, if those ZFS numbers are even with FUSE in the way, Linux really should be embarrassed.

Personally, I hope that Sun puts ZFS under the GPLv3 or later only. I would have a hearty laugh.

I thought the *BSDs were getting it/had got it.

Possible... I don't really follow the BSDs so I am unaware of this.

Ayup.  Status here:
http://wiki.freebsd.org/ZFS

One of the main differences between Linux and FreeBSD is GEOM. FreeBSD went through a huge hit in order to refactor the disk subsystems at around 5.0.

It paid off with porting ZFS, though.

Linux is going to have to suffer the same pain eventually. And, boy, is it pain. *Everybody* hates you during the changeover (just ask phk from FreeBSD land).
