Nice work. However, I think we can simplify this a bit more, see comments.

Almost there. :-) Could you please comment or fix the one comment on logging dropped lines!

I have one more general question tough: Your PR adds dataset-collection to FreeBSD but it sould also work on e.g. Linux. What about those poor souls? Do you think you can make it also work on Linux? I'll be able to test it here...

@srebhan I added a log but I'm sorry but I have no experience with ZFS on linux.

Hey @zozoh94, I think linux behaves exactly the same as *BSD there. When calling zfs list -Hp -o name,avail,used,usedsnap,usedds on linux I get

mytestpool      7318564864      482809856       0       482642432
mytestpool/mydataset1   7318564864      24576   0       24576
mytestpool/mydataset2   7318564864      24576   0       24576
mytestpool/mydataset3   7318564864      24576   0       24576

as output. So I guess it's pretty much the same you're seeing on FreeBSD!? However, I realized the Linux code relies on directly reading /proc... So never mind.

FWIW, the freebsd-code also works with linux, see a crappy port at toelke@fae76e8
