[zfs-devel] First review for externally compressed data (IPCC)

the work I'm doing  is for my bachelor thesis, which has a deadline
in mid January. Therefore it would be great to get some feedback,
ideally before Christmas.
Our idea is to create another pull request when the code is done
(hopefully in January next year). So, the sooner I get feedback (even if
it's superficial), the sooner I can work on potential bugs or improvements.
As I said, it would be really great to get some Feedback before the end
of the year.
