There’s been some Friday night kernel drama on the Linux kernel mailing list… Linus Torvalds has expressed regrets for merging the Bcachefs file-system and an ensuing back-and-forth between the file-system maintainer.
License incompatibility is one big reason OpenZFS is not in-tree for Linux, there is plenty of public discussion about this online.
Like this that states there is no issue https://opensource.stackexchange.com/questions/2094/are-cddl-and-gpl-really-incompatible
Yes, but note that neither the Linux foundation nor OpenZFS are going to put themselves in legal risk on the word of a stack exchange comment, no matter who it’s from. Even if their legal teams all have no issue, Oracle has a reputation for being litigious and the fact that they haven’t resolved the issue once and for all despite the fact they could suggest they’re keeping the possibility of litigation in their back pocket (regardless of if such a case would have merit).
Canonical has said they don’t think there is an issue and put their money where their mouth was, but they are one of very few to do so.
