No beef: I just simply don't run out of tree kernel code, I've been burned too many times. Linux ZFS is mostly used by hobbyists and tinkerers, it doesn't get anything close to the amount of real world production testing and follow up bugfixing with linux that a real upstream filesystem like btrfs does today.
If ZFS ever goes upstream, I will certainly enjoy tinkering with it. But until it does, I just don't see the point, I build my own kernels and dealing with the external code isn't worth the trouble. There's already more than enough to tinker with :)

All my FreeBSD machines run ZFS, FWIW.
