> Running any filesystem outside the mainline kernel is a bunch of extra effort and I’m sure as a ZFS user you’d know that zfs-dkms makes usage simple since openzfs backwards compatible down to 3.xx kernels. no need to mix match zfs with kernel versions anymore. the only drawback is that you may not get to use the lastest kernel until openzfs mantainers give it the thumbs up (no 6.xx compatible release yet), but that's not "a bunch of extra effort". and that's only a problem if you want to be in the bleeding edge. LTS kernel users wouldn't know about it. > I’m not sure how ZFS could be “hugely successful” after two decades and still not in the Linux kernel. "There is no way I can merge any of the ZFS efforts until I get an official letter from Oracle that is signed by their main legal counsel or preferably by Larry Ellison himself that says that yes, it's OK to do so and treat the end result as GPL'd" -Linus Torvalds sound like a legal issue more than technical.
