Several patches landed and will land soon that collide with this patch. I have a local port and will start testing now that I have Ubuntu18 setup.</p> <p>Wow. Setting up my Ubuntu 18 test system I discovered zfs is installed by default.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="https://review.whamcloud.com/31789/"
