There's one thing you're overlooking: the core kernel developers have
already stated that ZFS is a "rampant layering violation" and otherwise
indicated they do not want ZFS in the Linux kernel, whereas BtrFS has
gotten a much more positive response. It may well be that on the /Oracle/
side, the political and technical problems with porting ZFS are smaller than
those with finishing BtrFS, but if the kernel developers wouldn't accept it,
_any_ money and effort spent on it would be wasted money and effort.
