Basically, ZoL and FreeBSD had Illumos as our upstream. ZoL has added a
bunch in a way that could be upstreamed, but weren't due to the extreme
slow pace of Illumos taking changes, as well as viability issues with
Illumos. FreeBSD is rebasing from Illumos to ZoL because the official
upstream of OpenZFS is moving from Illumos to ZoL because the efforts of
adding the missing bits since the fork to ZoL was much smaller than vice
versa. ZoL is an unfortunate name because it has the trigger word Linux in
it. The ZoL folks are not the LKM folks, but quite reasonable people
without the GPL politics getting in the way that caused Linux to be such a
trigger word.
